Changelog

* Thu Jun 23 2022 Detlef Steuer <detlef.steuer@gmx.de>
  - CHANGES IN R 4.2.1:
    NEW FEATURES:
    * New function utils::findCRANmirror() to find out if a CRAN mirror
      has been selected, otherwise fallback to the main site.  This
      behaves in the same way as tools::CRAN_package_db() and is
      intended for packages wishing to access CRAN for purposes other
      than installing packages.
      The need for this was shown by a day when the main CRAN website
      was offline and a dozen or so packages which had its URL
      hardcoded failed their checks.
    INSTALLATION on a UNIX-ALIKE:
    * The libraries searched for by --with-blas (without a value) now
      include BLIS (after OpenBLAS but before ATLAS).  And on macOS,
      the Accelerate framework (after ATLAS).  (This is patterned after
      the AX_BLAS macro from the Autoconf Archive.)
    * The included LAPACK sources have been updated to 3.10.1.
    UTILITIES:
    * The (full path to) the command tidy to be used for HTML
      validation can be set by environment variable R_TIDYCMD.
    * Setting environment variable _R_CHECK_RD_VALIDATE_RD2HTML_ to a
      false value will override R CMD check --as-cran and turn off HTML
      validation.  This provides a way to circumvent a problematic
      tidy.
      The 2006 version that ships with macOS is always skipped.
    C-LEVEL FACILITIES:
    * The undocumented legacy declarations of Sint, Sfloat, SINT_MAX
      and SINT_MIN in header R.h are deprecated.
    BUG FIXES:
    * fisher.test(d) no longer segfaults for "large" d; fixing PR#18336
      by preventing/detecting an integer overflow reliably.
    * tar(., files=*) now produces correctly the warning about invalid
      uid or gid of files, fixing PR#18344, reported by Martin Morgan.
    * tk_choose.files() with multi = FALSE misbehaved on paths
      containing spaces (PR#18334) (regression introduced in R 4.0.0).
    * sort(x, partial = ind, *) now works correctly notably for the
      non-default na.last = FALSE or TRUE, fixing PR#18335 reported by
      James Edwards.
    * Environment variable _R_CHECK_XREFS_REPOSITORIES_ is only used
      for checking .Rd cross-references in R CMD check (as documented)
      and not for other uses looking for a CRAN mirror.
    * The search for a CRAN mirror when checking packages now uses
      getOption("repos") if that specifies a CRAN mirror, even when it
      does not also specify all three Bioconductor repositories (as was
      previously required).
    * The HTML code generated by tools::Rd2HTML() has been improved to
      pass tidy 5.8.0.
* Fri Apr 22 2022 Detlef Steuer <detlef.steuer@gmx.de>
  - CHANGES IN R 4.2.0:
    SIGNIFICANT USER-VISIBLE CHANGES:
    * The formula method of aggregate() now matches the generic in
      naming its first argument x (resolving PR#18299 by Thomas
      Soeiro).
      This means that calling aggregate() with a formula as a named
      first argument requires name formula in earlier versions of R and
      name x now, so portable code should not name the argument (code
      in many packages did).
    * Calling && or || with either argument of length greater than one
      now gives a warning (which it is intended will become an error).
    * Calling if() or while() with a condition of length greater than
      one gives an error rather than a warning.  Consequently,
      environment variable _R_CHECK_LENGTH_1_CONDITION_ no longer has
      any effect.
    * Windows users should consult the WINDOWS section below for some
      profound changes including
    * Support for 32-bit builds has been dropped.
    * UTF-8 locales are used where available.
    * The default locations for the R installation and personal
      library folder have been changed.
      Thanks to Tomas Kalibera for months of work on the Windows port
      for this release.
    NEW FEATURES:
    * matrix(x, n, m) now warns in more cases where length(x) differs
      from n * m, as suggested by Abby Spurdle and Wolfgang Huber in
      Feb 2021 on the R-devel mailing list.
      This warning can be turned into an error by setting environment
      variable _R_CHECK_MATRIX_DATA_ to TRUE: R CMD check --as-cran
      does so unless it is already set.
    * Function file_test() in package utils gains tests for symlinks,
      readability and writability.
    * capabilities("libxml") is now false.
      The description of capabilities("http/ftp") now reflects that it
      refers to the default method, no longer the internal one.
    * simplify2array() gains an except argument for controlling the
      exceptions used by sapply().
    * Environment variables R_LIBS_USER and R_LIBS_SITE are both now
      set to the R system default if unset or empty, and can be set to
      NULL to indicate an empty list of user or site library
      directories.
    * The warning for axis()(-like) calls in cases of relatively small
      ranges (typically in log-scale situations) is slightly improved
      _and_ suppressed from explicit calls to .axisPars() as has always
      been the intention.
    * The contrasts setter function `contrasts<-` gains an explicit
      default how.many = NULL rather than just using missing(how.many).
    * grid.pretty() gains a new optional argument n = 5.
    * There is a new function .pretty() with option bounds as a
      technical-utility version of pretty().  It and pretty() gain a
      new argument f.min with a better than back-compatible default.
    * Function grDevices::axisTicks() and related functions such as
      graphics::axis() work better, notably for the log scale; partly
      because of the pretty() improvements, but also because care is
      taken e.g., when ylim is finite but diff(ylim) is infinite.
    * nclass.FD() gains a digits option.
    * The R Mathlib internal C function bd0() (called indirectly from a
      dozen probability density and distribution functions such as
      dpois(), dbinom(), dgamma(), pgamma() _etc_) has been
      complemented by a more sophisticated and (mostly) more accurate C
      function ebd0(), currently called only by internal dpois_raw()
      improving accuracy for R level dpois() and potentially others
      calling it such as dnbinom(), dgamma() or pgamma().  (Thanks to
      Morten Welinder's PR#15628.)
    * write.ftable() gains sep = " " argument as suggested by Thomas
      Soeiro.
    * The names of the locale categories supported by R's
      Sys.getlocale() and Sys.setlocale() are now provided by variable
      .LC.categories in the base namespace.
    * The Date and POSIXt methods for hist() and the histogram method
      for plot() now also use the new default col = "lightgray" in
      consistency with the corresponding change to hist()'s default for
      R 4.0.0.
    * hist.default() gains new fuzz argument, and the histogram plot
      method no longer uses fractional axis ticks when displaying
      counts ("Frequency").
    * mapply() and hence Map() now also obey the "max-or-0-if-any"
      recycling rule, such that, e.g., Map(`+`, 1:3, 1[0]) is valid
      now.
    * as.character(<obj>) for "hexmode" or "octmode" objects now
      fulfils the important basic rule as.character(x)[j] ===
      as.character(x[j]).
    * The set utility functions, notably intersect() have been tweaked
      to be more consistent and symmetric in their two set arguments,
      also preserving a common mode.
    * substr(ch, start,end) <- new now e.g., preserves names(ch); ditto
      for substring(), thanks to a patch from Brodie Gaslam.
    * plot(<lm>) gains a extend.ylim.f argument, in partial response to
      PR#15285; further PR#17784 is fixed thanks to several
      contributors and a patch by Elin Waring.  The Cook's dist
      contours get customizable via cook.col and cook.lty with a
      different default color and their legend is nicer by default and
      customizable via cook.legendChanges.
    * Attempting to subset an object that is not subsettable now
      signals an error of class notSubsettableError. The
      non-subsettable object is contained in the object field of the
      error condition.
    * Subscript-out-of-bounds errors are now signaled as errors of
      class subscriptOutOfBoundsError.
    * Stack-overflow errors are now signaled as errors inheriting from
      class stackOverflowError. See ?stackOverflowError for more
      details.
    * New partly experimental Sys.setLanguage() utility, solving the
      main problem of PR#18055.
    * gettext() and gettextf() get a new option trim = TRUE which when
      set to false allows translations for strings such as "Execution
      halted\n" typical for C code.
    * An experimental implementation of hash tables is now available.
      See ?hashtab for more details.
    * identical() gains a extptr.as.ref argument for requesting that
      external pointer objects be compared as reference objects.
    * reorder() gets an argument decreasing which it passes to sort()
      for level creation; based on the wish and patch by Thomas Soeiro
      in PR#18243.
    * as.vector() gains a data.frame method which returns a simple
      named list, also clearing a long standing 'FIXME' to enable
      as.vector(<data.frame>, mode="list").  This breaks code relying
      on as.vector(<data.frame>) to return the unchanged data frame.
    * legend() is now vectorized for arguments cex, x.intersp, and
      text.width.  The latter can now also be specified as a vector
      (one element for each column of the legend) or as NA for
      computing a proper column wise maximum value of strwidth(legend).
      The argument y.intersp can be specified as a vector with one
      entry for each row of the legend.
      legend() also gains new arguments title.cex and title.font.
      Thanks to Swetlana Herbrandt.
    * Deparsing no longer remaps attribute names dim, dimnames, levels,
      names and tsp to historical S-compatible names (which structure()
      maps back).
    * sample() and sample.int() have additional sanity checks on their
      size and n arguments.
      all.equal.numeric() gains a sanity check on its tolerance
      argument - calling all.equal(a, b, c) for three numeric vectors
      is a surprisingly common error.
      mean(na.rm =), rank(na.last =), barplot(legend.text =),
      boxplot(), contour(drawlabels =), polygon(border =) and
      methods::is(class2 =) have more robust sanity checks on their
      arguments.
      R CMD Rd2pdf (used by R CMD check) has a more robust sanity check
      on the format of \alias{} commands.
    * psigamma(x, deriv) for negative x now also works for deriv = 4
      and 5; their underlying C level dpsifn() is documented in
      'Writing R Extensions'.
    * The HTML help system now uses HTML5 (wish of PR#18149).
    * ks.test() now provides exact p-values also with ties and MC
      p-values in the two-sample (Smirnov) case.  By Torsten Hothorn.
    * ks.test() gains a formula interface, with y ~ 1 for the
      one-sample (Kolmogorov) test and y ~ group for the two-sample
      (Smirnov) test.  Contributed by Torsten Hothorn.
    * The return value from ks.test() now has class c("ks.test",
      "htest") - packages using try() need to take care to use
      inherits() and not == on the class.
    * New functions psmirnov(), qsmirnov() and rsmirnov() in package
      stats implementing the asymptotic and exact distributions of the
      two-sample Smirnov statistic.
    * iconv() now allows sub = "c99" to use C99-style escapes for UTF-8
      inputs which cannot be converted to encoding to.
    * In a forward pipe |> expression it is now possible to use a named
      argument with the placeholder _ in the rhs call to specify where
      the lhs is to be inserted.  The placeholder can only appear once
      on the rhs.
    * The included LAPACK sources have been updated to version 3.10.0,
      except for the four Fortran 77 routines which 3.10.0 has
      re-implemented in Fortran 90 (where the older versions have been
      retained as the R build process does not support Fortran 90).
    * path.expand() and most other uses of tilde expansion now warn if
      a path would be too long if expanded.  (An exception is
      file.exists(), which silently returns false.)
    * trunc(<Date>, *) now supports units = "months" or "years" for
      consistency with the POSIXt method, thanks to Dirk Eddelbuettel's
      proposal in PR#18099.
    * list2DF() now checks that its arguments are of the same length,
      rather than use recycling.
    * The HTML help system has several new features: LaTeX-like math
      can be typeset using either KaTeX or MathJax, usage and example
      code is highlighted using Prism, and for dynamic help the output
      of examples and demos can be shown within the browser if the
      knitr package is installed. These features can be disabled by
      setting the environment variable _R_HELP_ENABLE_ENHANCED_HTML_ to
      a false value.
    GRAPHICS:
    * The graphics engine version, R_GE_version, has been bumped to 15
      and so packages that provide graphics devices should be
      reinstalled.
    * The grid package now allows the user to specify a "vector" of
      pattern fills.  The fill argument to gpar() accepts a list of
      gradients and/or patterns and the functions linearGradient(),
      radialGradient(), and pattern() have a new group argument.
      Points grobs (data symbols) can now also have a pattern fill.
      The grobCoords() function now returns a more informative and
      complex result.
    * The grid package has new functions for drawing isolated groups:
      grid.group(), grid.define(), and grid.use().  These functions add
      compositing operators and affine transformations to R's graphics
      capabilities.
      The grid package also has new functions for stroking and filling
      paths: grid.stroke(), grid.fill(), and grid.fillStroke().
      A new function as.path() allows the user to specify the fill rule
      for a path that is to be used for clipping, stroking, or filling;
      available options are "winding" and "evenodd".  A new function
      as.mask() allows the user to specify the type of a mask;
      available options are "alpha" and "luminance".
      These new features are only supported so far (at most) on the
      Cairo-based graphics devices and on the pdf() device.
    * dev.capabilities() reports on device support for the new
      features.
    * par() now warns about unnamed non-character arguments to prevent
      misuse such as {usr <- par("usr"); par(usr)}.
    INSTALLATION:
    * Facilities for accessing ftp:// sites are no longer tested
      (except _pro tem_ for curlGetHeaders()) as modern browsers have
      removed support.
    * R can now be built with DEFS = -DSTRICT_R_HEADERS .
    PACKAGE INSTALLATION:
    * R CMD INSTALL no longer tangles vignettes. This completes an R
      CMD build change in R 3.0.0 and affects packages built before R
      3.0.2. Such packages should be re-made with R CMD build to have
      the tangled R code of vignettes shipped with the tarball.
    * USE_FC_LEN_T will become the default: this uses the correct
      prototypes for Fortran BLAS/LAPACK routines called from C/C++,
      and requires adjustment of most such calls - see 'Writing R
      Extensions' SS6.6.2.  (This has been supported since R 3.6.2.)
    * Package installation speed for packages installed with
      keep.source has been improved. This resolve the issue reported by
      Ofek Shilon in PR#18236.
    UTILITIES:
    * R CMD check can optionally report files/directories left behind
      in home, /tmp (even though TMPDIR is set) and other directories.
      See the "R Internals" manual for details.
    * R CMD check now reports byte-compilation errors during
      installation.  These are not usually fatal but may result in
      parts of the package not being byte-compiled.
    * _R_CHECK_DEPENDS_ONLY_ can be applied selectively to examples,
      tests and/or vignettes in R CMD check: see the "R Internals"
      manual.
    * _R_CHECK_SRC_MINUS_W_IMPLICIT_ now defaults to true: recent
      versions of Apple clang on macOS have made implicit function
      declarations in C into a compilation error.
    * R CMD check --as-cran makes use of the environment variable
      AUTORECONF.  See the "R Internals" manual SS8 for further details.
    * R CMD check --use-valgrind also uses valgrind when re-building
      vignettes as some non-Sweave vignettes unhelpfully comment out
      all their code when R CMD check runs vignettes.
    * Errors in re-building vignettes (unless there are LaTeX errors)
      are reported by R CMD check as ERROR rather than WARNING when
      running vignettes has been skipped (as it frequently is in CRAN
      checks and by --as-cran).
    * R CMD Rd2pdf gains a --quiet option that is used by R CMD build
      when building the PDF package manual.
    * R CMD Rd2pdf now always runs LaTeX in batch mode, consistent with
      Texinfo >= 6.7. The --batch option is ignored.
    * R CMD build and R CMD check now include the Rd file name and line
      numbers in the error message of an \Sexpr evaluation failure.
    * For packages using the \doi Rd macro (now an install-time \Sexpr)
      but no other dynamic Rd content, R CMD build now produces a
      smaller tarball and is considerably faster - skipping temporary
      package installation.
    C-LEVEL FACILITIES:
    * The non-API header R_ext/R-ftp-http.h is no longer provided, as
      the entry points it covered are now all defunct.
    * A number of non-API declarations and macro definitions have been
      moved from the installed header Rinternals.h to the internal
      header Defn.h. Packages that only use entry points and
      definitions documented to be part of the API as specified in
      'Writing R Extensions' SS6 should not be affected.
    * The macro USE_RINTERNALS no longer has any effect when compiling
      package code.  Packages which also use R_NO_REMAP will need to
      ensure that the remapped names are used for calls to API
      functions that were formerly also made available as macros.
    * The deprecated legacy S-compatibility macros PROBLEM, MESSAGE,
      ERROR, WARN, WARNING, RECOVER, ... are no longer defined in
      R_exts/RS.h (included by R.h).  Replace these by calls to
      Rf_error and Rf_warning (defined in header R_ext/Error.h included
      by R.h).
      Header R_ext/RS.h no longer includes R_ext/Error.h.
    * Header R_ext/Constants.h (included by R.h) when included from C++
      now includes the C++ header cfloat rather than the C header
      float.h (now possible as C++11 is required).
    * The legacy S-compatibility macros DOUBLE_* in R_ext/Constants.h
      (included by R.h) are deprecated.
    * The deprecated S-compatibility macros SINGLE_* in
      R_ext/Constants.h (included by R.h) have been removed.
    * R_Calloc, R_Free and R_Realloc are preferred to their unprefixed
      forms and error messages now use the prefix. These forms were
      introduced in R 3.4.0 and are available even when
      STRICT_R_HEADERS is defined.
    * rmultinom has been documented in 'Writing R Extensions' SS6 so is
      now part of the R API.
    * Similarly, Rtanpi, called from R level tanpi() is now part of the
      R API.
    * The long-deprecated, undocumented and non-API entry point call_R
      is no longer declared in R_ext/RS.h (included by R.h).
    * The header S.h which has been unsupported since Jan 2016 has been
      removed.  Use R.h instead.
    DEPRECATED AND DEFUNCT:
    * The (non-default and deprecated) method = "internal" for
      download.file() and url() no longer supports http:// nor ftp://
      URIs.  (It is used only for file:// URIs.)
      On Windows, download.file(method = "wininet") no longer supports
      ftp:// URIs.  (It is no longer the default method, which is
      "libcurl" and does.)
      On Windows, the deprecated method = "wininet" now gives a warning
      for http:// and https:// URIs for both download.file() and url().
      (It is no longer the default method.)
    * On Windows, the command-line option --max-mem-size and
      environment variable R_MAX_MEM_SIZE are defunct.  The memory
      allocation limit was important for 32-bit builds, but these are
      no longer supported.
    * default.stringsAsFactors() is now formally deprecated, where that
      was only mentioned on its regular help page, previously.  So it
      now gives a warning if called.
    * unix.time() is defunct now; it had been deprecated since R 3.4.0.
    BUG FIXES:
    * Setting digits = 0 in format(), print.default() (and hence
      typically print()) or options() is again invalid.  Its behaviour
      was platform-dependent, and it is unclear what "zero significant
      digits" should mean (PR#18098).
    * Messages from C code in the cairo section of package grDevices
      are now also offered for translation, thanks to Michael Chirico's
      PR#18123.
    * mean(x) with finite x now is finite also without "long.double"
      capability.
    * R CMD Rd2pdf no longer leaves an empty build directory behind
      when it aborts due to an already existing output file.  (Thanks
      to Sebastian Meyer's PR#18141.)
    * density(x, weights = w, na.rm = TRUE) when anyNA(x) is true, now
      removes weights "in parallel" to x, fixing PR#18151, reported by
      Matthias Gondan.  Additionally, it gets a subdensity option.
    * Conversion of \Sexpr[]{<expR>} to LaTeX or HTML no longer
      produces long blocks of empty lines when <expR> itself contains
      several lines all producing empty output.  Thanks to a report and
      patch by Ivan Krylov posted to R-devel.
    * R CMD build no longer fails if a package vignette uses child
      documents and inst/doc exists.  (Thanks to Sebastian Meyer's
      PR#18156.)
    * When an R documentation ('help' source) file man/foo.Rd in a
      package has \donttest{..} examples with a syntax error, it is now
      signalled as ERROR and with correct line numbers relating to the
    * -Ex.R file, thanks to Duncan Murdoch and Sebastian Meyer's
      reports and patch proposals in PR#17501.
    * Improved determination of the correct translation domain in
      non-base packages, addressing the combination of PR#18092 and
      PR#17998 (#c6) with reports and _augmented_ patch #2904 by
      Suharto Anggono.
      Note that "R-base" is no longer the default domain e.g., for
      top-level calls to gettext(); rather translation needs explicit
      domain = * specification in such cases.
    * identical(attrib.as.set=FALSE) now works correctly with data
      frames with default row names (Thanks to Charlie Gao's PR#18179).
    * txtProgressBar() now enforces a non-zero width for argument char,
      without which no progress can be visible.
    * dimnames(table(d)) is more consistent in the case where d is a
      list with a single component, thanks to Thomas Soeiro's report to
      R-devel.
      Further, table(d1, d2) now gives an error when d1 and d2 are data
      frames as suggested by Thomas in PR#18224.
    * Fix for drawing semi-transparent lines and fills on the native
      Windows graphics device (PR#18219 and PR#16694).  Thanks to Nick
      Ray for helpful diagnosis on Bugzilla.
    * The deparser now wraps sub-expressions such as if(A) ..  with
      parentheses when needed; thanks to Duncan Murdoch's PR#18232 and
      Lionel Henry's patches there.
    * remove.packages() no longer tries to uninstall Priority: base
      packages, thanks to a report and suggestions by Colin Fay in
      PR#18227.
    * win.metafile() now has xpinch and ypinch arguments so that the
      user can override Windows' (potentially wrong) guess at device
      dimensions.
    * x[i] and x[[i]] for non-integer i should now behave in all cases
      as always documented: the index used is equivalent to
      as.integer(i) unless that would overflow where trunc(i) is used
      instead; thanks to Suharto Anggono's report and patch proposals
      in PR#17977.
    * asOneSidedFormula() now associates the resulting formula with the
      global environment rather than the evaluation environment created
      for the call.
    * <bibentry>$name now matches the field name case-insensitively,
      consistent with bibentry() creation and the replacement method.
    * cbind() failed to detect some length mismatches with a mixture of
      time-series and non-time-series inputs.
    * The default LaTeX style file Sweave.sty used by the RweaveLatex
      driver no longer loads the obsolete ae package; thanks to a
      report by Thomas Soeiro in PR#18271.  Furthermore, it now skips
      \usepackage[T1]{fontenc} for engines other than pdfTeX (if
      detected) or if the new [nofontenc] option is used.
    * smooth.spline() now stores its logical cv argument more safely,
      fixing a rare bug when printing, and also stores n.
    * smooth.spline(x,y,*) now computes the cv.crit statistic
      correctly, also when is.unsorted(x), fixing PR#18294.
    * The data.frame method of rbind() now warns when binding
      not-wholly-recycling vectors, by analogy to the default method
      (for matrices).
    * setAs() finds the correct class for name to when multiple
      packages define a class with that name. Thanks to Gabor Csardi
      for the report.
    * Fix for detaching a package when two classes of the same name are
      present in method signatures for the same generic. Thanks to
      Gabor Csardi for the report.
    * match.arg("", c("", "a", "B")) gives a better error message, in
      part from PR#17959, thanks to Elin Waring.
    * R CMD Sweave --clean no longer removes pre-existing files or
      subdirectories (PR#18242).
    * The quartz() device no longer splits polylines into subpaths.
      That has caused narrowly-spaced lines with many points to always
      look solid even when dashed line type was used due to dash phase
      restarts.
    * Deparsing constructs such as quote(1 + `!`(2) + 3) works again as
      before R 3.5.0, thanks to the report and patch in PR#18284 by
      Suharto Anggono.
    * as.list(f) for a factor f now keeps names(f), fixing PR#18309.
    * qbeta(.001, .9, .009) and analogous qf() calls now return a
      correct value instead of NaN or wrongly 1, all with a warning;
      thanks to the report by Ludger Goeminne in PR#18302.
    * plot.lm() failed to produce the plot of residuals vs.  factor
      levels (i.e., which=5 when leverages are constant) for models
      with character predictors (PR#17840).
    * interaction.plot(..., xtick = TRUE) misplaced the x-axis line
      (PR#18305).
    * Not strictly fixing a bug, format()ing and print()ing of
      non-finite Date and POSIXt values NaN and +/-Inf no longer show
      as NA but the respective string, e.g., Inf, for consistency with
      numeric vector's behaviour, fulfilling the wish of PR#18308.
    * R CMD check no longer runs test scripts generated from
      corresponding .Rin files twice and now signals an ERROR if
      processing an .Rin script fails.
    * tools::Rd2txt() used for plain-text help pages now renders \hrefs
      (if tools::Rd2txt_options(showURLs = TRUE)) and \urls with
      percent-encoding and standards-compliant delimiting style (angle
      brackets and no URL: prefix).  \email is now rendered with a
      mailto: prefix.
* Fri Mar 11 2022 Detlef Steuer <detlef.steuer@gmx.de>
  - CHANGES IN R 4.1.3:
    NEW FEATURES:
    * The default version of Bioconductor has been changed to 3.14.
      (This is used by setRepositories and the menus in GUIs.)
    UTILITIES:
    * R CMD check --as-cran has a workaround for a bug in versions of
      file up to at least 5.41 which mis-identify DBF files last
      changed in 2022 as executables.
    C-LEVEL FACILITIES:
    * The legacy S-compatibility macros SINGLE_* in R_ext/Constants.h
      (included by R.h) are deprecated and will be removed in R 4.2.0.
    BUG FIXES:
    * Initialization of self-starting nls() models with initialization
      functions following the pre-R-4.1.0 API (without the ...
      argument) works again for now, with a deprecation warning.
    * Fixed quoting of ~autodetect~ in Java setting defaults to avoid
      inadvertent user lookup due to leading ~, reported in PR#18231 by
      Harold Gutch.
    * substr(., start, stop) <- v now treats _negative_ stop values
      correctly.  Reported with a patch in PR#18228 by Brodie Gaslam.
    * Subscripting an array x without dimnames by a
      length(dim(x))-column character matrix gave "random" non-sense,
      now an error; reported in PR#18244 by Mikael Jagan.
    * ...names() now matches names(list(...)) closely, fixing PR#18247.
    * all.equal(*, scale = s) now works as intended when length(s) > 1,
      partly thanks to Michael Chirico's PR#18272.
    * print(x) for long vectors x now also works for named atomic
      vectors or lists and prints the correct number when reaching the
      getOption("max.print") limit; partly thanks to a report and
      proposal by Hugh Parsonage to the R-devel list.
    * all.equal(<selfStart>, *) no longer signals a deprecation
      warning.
    * reformulate(*, response=r) gives a helpful error message now when
      length(r) > 1, thanks to Bill Dunlap's PR#18281.
    * Modifying globalCallingHandlers inside withCallingHandlers() now
      works or fails correctly, thanks to Henrik Bengtsson's PR#18257.
    * hist(<Date>, breaks = "days") and hist(<POSIXt>, breaks = "secs")
      no longer fail for inputs of length 1.
    * qbeta(.001, .9, .009) and similar cases now converge correctly
      thanks to Ben Bolker's report in PR#17746.
    * window(x, start, end) no longer wrongly signals "'start' cannot
      be after 'end'", fixing PR#17527 and PR#18291.
    * data() now checks that its (rarely used) list argument is a
      character vector - a couple of packages passed other types and
      gave incorrect results.
    * which() now checks its arr.ind argument is TRUE rather coercing
      to logical and taking the first element - which gave incorrect
      results in package code.
    * model.weights() and model.offset() more carefully extract their
      model components, thanks to Ben Bolker and Tim Taylor's R-devel
      post.
    * list.files(recursive = TRUE) now shows all broken symlinks
      (previously, some of them may have been omitted, PR#18296).
* Mon Nov 01 2021 Detlef Steuer <detlef.steuer@gmx.de>
  - CHANGES IN R 4.1.2:
    C-LEVEL FACILITIES:
    * The workaround in headers R.h and Rmath.h (using namespace std;)
      for the Oracle Developer Studio compiler is no longer needed now
      C++11 is required so has been removed.  A couple more usages of
      log() (which should have been std::log()) with an int argument
      are reported on Solaris.
    * The undocumented limit of 4095 bytes on messages from the
      S-compatibility macros PROBLEM and MESSAGE is now documented and
      longer messages will be silently truncated rather than
      potentially causing segfaults.
    * If the R_NO_SEGV_HANDLER environment variable is non-empty, the
      signal handler for SEGV/ILL/BUS signals (which offers recovery
      user interface) is not set. This allows more reliable debugging
      of crashes that involve the console.
    DEPRECATED AND DEFUNCT:
    * The legacy S-compatibility macros PROBLEM, MESSAGE, ERROR, WARN,
      WARNING, RECOVER, ... are deprecated and will be hidden in R
      4.2.0. R's native interface of Rf_error and Rf_warning has long
      been preferred.
    BUG FIXES:
    * .mapply(F, dots, .) no longer segfaults when dots is not a list
      and uses match.fun(F) as always documented; reported by Andrew
      Simmons in PR#18164.
    * hist(<Date>, ...) and hist(<POSIXt>, ...)  no longer pass
      arguments for rect() (such as col and density) to axis().
      (Thanks to Sebastian Meyer's PR#18171.)
    * \Sexpr{ch} now preserves Encoding(ch). (Thanks to report and
      patch by Jeroen Ooms in PR#18152.)
    * Setting the RNG to "Marsaglia-Multicarry" e.g., by RNGkind(), now
      warns in more places, thanks to Andr'e Gillibert's report and
      patch in PR#18168.
    * gray(numeric(), alpha=1/2) no longer segfaults, fixing PR#18183,
      reported by Till Krenz.
    * Fixed dnbinom(x, size=<very_small>, .., log=TRUE) regression,
      reported by Martin Morgan.
    * as.Date.POSIXlt(x) now keeps names(x), thanks to Davis Vaughan's
      report and patch in PR#18188.
    * model.response() now strips an "AsIs" class typically, thanks to
      Duncan Murdoch's report and other discussants in PR#18190.
    * try() is considerably faster in case of an error and long call,
      as e.g., from some do.call().  Thanks to Alexander Kaever's
      suggestion posted to R-devel.
    * qqline(y = <object>) such as y=I(.), now works, see also
      PR#18190.
    * Non-integer mgp par() settings are now handled correctly in
      axis() and mtext(), thanks to Mikael Jagan and Duncan Murdoch's
      report and suggestion in PR#18194.
    * formatC(x) returns length zero character() now, rather than ""
      when x is of length zero, as documented, thanks to Davis
      Vaughan's post to R-devel.
    * removeSource(fn) now retains (other) attributes(fn).
* Mon Oct 25 2021 Detlef Steuer <detlef.steuer@gmx.de>
  - repaired https://bugzilla.suse.com/show_bug.cgi?id=1191380
    (rpmacros now go to rpmmacrodir)
  - minor clean-ups in spec file
* Tue Aug 10 2021 Detlef Steuer <detlef.steuer@gmx.de>
  - CHANGES IN R 4.1.1:
    NEW FEATURES:
    * require(pkg, quietly = TRUE) is quieter and in particular does
      not warn if the package is not found.
    DEPRECATED AND DEFUNCT:
    * Use of ftp:// URIs should be regarded as deprecated, with
      on-going support confined to method = "libcurl" and not routinely
      tested.  (Nowadays no major browser supports them.)
    * The non-default method = "internal" is deprecated for http:// and
      ftp:// URIs for both download.file and url.
    * On Windows, method = "wininet" is deprecated for http://,
      https:// and ftp:// URIs for both download.file and url.  (A
      warning is only given for ftp://.)
      For ftp:// URIs the default method is now "libcurl" if available
      (which it is on CRAN builds).
      method = "wininet" remains the default for http:// and https://
      URIs but if libcurl is available, using method = "libcurl" is
      preferred.
    INSTALLATION:
    * make check now works also without a LaTeX installation.  (Thanks
      to Sebastian Meyer's PR#18103.)
    BUG FIXES:
    * make check-devel works again in an R build configured with
    - -without-recommended-packages.
    * qnbinom(p, size, mu) for large size/mu is correct now in a range
      of cases (PR#18095); similarly for the (size, prob)
      parametrization of the negative binomial.  Also qpois() and
      qbinom() are better and or faster for extreme cases.  The
      underlying C code has been modularized and is common to all four
      cases of discrete distributions.
    * gap.axis is now part of the axis() arguments which are passed
      from bxp(), and hence boxplot().  (Thanks to Martin Smith's
      report and suggestions in PR#18109.)
    * .First and .Last can again be set from the site profile.
    * seq.int(from, to, *) and seq.default(..) now work better in large
      range cases where from-to is infinite where the two boundaries
      are finite.
    * all.equal(x,y) now returns TRUE correctly also when several
      entries of abs(x) and abs(y) are close to .Machine$double.xmax,
      the largest finite numeric.
    * model.frame() now clears the object bit when removing the class
      attribute of a value via na.action (PR#18100).
    * charClass() now works with multi-character strings on Windows
      (PR#18104, fixed by Bill Dunlap).
    * encodeString() on Solaris now works again in Latin-1 encoding on
      characters represented differently in UTF-8.  Support for
      surrogate pairs on Solaris has been improved.
    * file.show() on Windows now works with non-ASCII path names
      representable in the current native encoding (PR#18132).
    * Embedded R on Windows can now find R home directory via the
      registry even when installed only for the current user
      (PR#18135).
    * pretty(x) with finite x now returns finite values also in the
      case where the extreme x values are close in size to the maximal
      representable number .Machine$double.xmax.
      Also, it's been tweaked for very small ranges and when a boundary
      is close (or equal) to zero; e.g., pretty(c(0,1e-317)) no longer
      has negative numbers, currently still warning about a very small
      range, and pretty(2^-(1024 - 2^-1/(c(24,10)))) is more accurate.
    * The error message for not finding vignette files when weaving has
      correct file sizes now. (Thanks to Sebastian Meyer's PR#18154.)
    * dnbinom(20, <large>, 1) now correctly gives 0, and similar cases
      are more accurate with underflow precaution.  (Reported by Francisco Vera Alcivar in PR#18072.)
* Fri Jun 04 2021 Detlef Steuer <detlef.steuer@gmx.de>
  - The line %{__install} -m 755 -d %{_infodir}
    no longer works in TW or Factory.
    But without that line it works everywhere. So this instruction
    was commented out of the spec file.
* Tue May 18 2021 Detlef Steuer <detlef.steuer@gmx.de>
  - CHANGES IN R 4.1.0:
    FUTURE DIRECTIONS:
    * It is planned that the 4.1.x series will be the last to support
      32-bit Windows, with production of binary packages for that
      series continuing until early 2023.
    SIGNIFICANT USER-VISIBLE CHANGES:
    * Data set esoph in package datasets now provides the correct
      numbers of controls; previously it had the numbers of cases added
      to these.  (Reported by Alexander Fowler in PR#17964.)
    NEW FEATURES:
    * www.omegahat.net is no longer one of the repositories known by
      default to setRepositories().  (Nowadays it only provides source
      packages and is often unavailable.)
    * Function package_dependencies() (in package tools) can now use
      different dependency types for direct and recursive dependencies.
    * The checking of the size of tarball in R CMD check --as-cran
      <pkg> may be tweaked via the new environment variable
      _R_CHECK_CRAN_INCOMING_TARBALL_THRESHOLD_, as suggested in
      PR#17777 by Jan Gorecki.
    * Using c() to combine a factor with other factors now gives a
      factor, an ordered factor when combining ordered factors with
      identical levels.
    * apply() gains a simplify argument to allow disabling of
      simplification of results.
    * The format() method for class "ftable" gets a new option justify.
      (Suggested by Thomas Soeiro.)
    * New ...names() utility.  (Proposed by Neal Fultz in PR#17705.)
    * type.convert() now warns when its as.is argument is not
      specified, as the help file always said it _should_.  In that
      case, the default is changed to TRUE in line with its change in
      read.table() (related to stringsAsFactor) in R 4.0.0.
    * When printing list arrays, classed objects are now shown _via_
      their format() value if this is a short enough character string,
      or by giving the first elements of their class vector and their
      length.
    * capabilities() gets new entry "Rprof" which is TRUE when R has
      been configured with the equivalent of --enable-R-profiling (as
      it is by default).  (Related to Michael Orlitzky's report
      PR#17836.)
    * str(xS4) now also shows extraneous attributes of an S4 object
      xS4.
    * Rudimentary support for vi-style tags in rtags() and R CMD rtags
      has been added.  (Based on a patch from Neal Fultz in PR#17214.)
    * checkRdContents() is now exported from tools; it and also
      checkDocFiles() have a new option chkInternal allowing to check
      Rd files marked with keyword "internal" as well.  The latter can
      be activated for R CMD check via environment variable
      _R_CHECK_RD_INTERNAL_TOO_.
    * New functions numToBits() and numToInts() extend the raw
      conversion utilities to (double precision) numeric.
    * Functions URLencode() and URLdecode() in package utils now work
      on vectors of URIs.  (Based on patch from Bob Rudis submitted
      with PR#17873.)
    * path.expand() can expand ~user on most Unix-alikes even when
      readline is not in use.  It tries harder to expand ~, for example
      should environment variable HOME be unset.
    * For HTML help (both dynamic and static), Rd file links to help
      pages in external packages are now treated as references to
      topics rather than file names, and fall back to a file link only
      if the topic is not found in the target package. The earlier rule
      which prioritized file names over topics can be restored by
      setting the environment variable _R_HELP_LINKS_TO_TOPICS_ to a
      false value.
    * c() now removes NULL arguments before dispatching to methods,
      thus simplifying the implementation of c() methods, _but_ for
      back compatibility keeps NULL when it is the first argument.
      (From a report and patch proposal by Lionel Henry in PR#17900.)
    * Vectorize()'s result function's environment no longer keeps
      unneeded objects.
    * Function ...elt() now propagates visibility consistently with
      ..n.  (Thanks to Lionel Henry's PR#17905.)
    * capture.output() no longer uses non-standard evaluation to
      evaluate its arguments.  This makes evaluation of functions like
      parent.frame() more consistent.  (Thanks to Lionel Henry's
      PR#17907.)
    * packBits(bits, type="double") now works as inverse of
      numToBits().  (Thanks to Bill Dunlap's proposal in PR#17914.)
    * curlGetHeaders() has two new arguments, timeout to specify the
      timeout for that call (overriding getOption("timeout")) and TLS
      to specify the minimum TLS protocol version to be used for
      https:// URIs (_inter alia_ providing a means to check for sites
      using deprecated TLS versions 1.0 and 1.1).
    * For nls(), an optional constant scaleOffset may be added to the
      denominator of the relative offset convergence test for cases
      where the fit of a model is expected to be exact, thanks to a
      proposal by John Nash.  nls(*, trace=TRUE) now also shows the
      convergence criterion.
    * Numeric differentiation _via_ numericDeriv() gets new optional
      arguments eps and central, the latter for taking central divided
      differences.  The latter can be activated for nls() via
      nls.control(nDcentral = TRUE).
    * nls() now passes the trace and control arguments to getInitial(),
      notably for all self-starting models, so these can also be fit in
      zero-noise situations via a scaleOffset.  For this reason, the
      initial function of a selfStart model must now have ... in its
      argument list.
    * bquote(splice = TRUE) can now splice expression vectors with
      attributes: this makes it possible to splice the result of
      parse(keep.source = TRUE).  (Report and patch provided by Lionel
      Henry in PR#17869.)
    * textConnection() gets an optional name argument.
    * get(), exists(), and get0() now signal an error if the first
      argument has length greater than 1.  Previously additional
      elements were silently ignored.  (Suggested by Antoine Fabri on
      R-devel.)
    * R now provides a shorthand notation for creating functions, e.g.
      \(x) x + 1 is parsed as function(x) x + 1.
    * R now provides a simple native forward pipe syntax |>.  The
      simple form of the forward pipe inserts the left-hand side as the
      first argument in the right-hand side call.  The pipe
      implementation as a syntax transformation was motivated by
      suggestions from Jim Hester and Lionel Henry.
    * all.equal(f, g) for functions now by default also compares their
      environment(.)s, notably via new all.equal method for class
      function.  Comparison of nls() fits, e.g., may now need
      all.equal(m1, m2, check.environment = FALSE).
    * .libPaths() gets a new option include.site, allowing to _not_
      include the site library.  (Thanks to Dario Strbenac's suggestion
      and Gabe Becker's PR#18016.)
    * Lithuanian translations are now available.  (Thanks to Rimantas
      Zakauskas.)
    * names() now works for DOTSXP objects.  On the other hand, in
      R-lang, the R language manual, we now warn against relying on the
      structure or even existence of such dot-dot-dot objects.
    * all.equal() no longer gives an error on DOTSXP objects.
    * capabilities("cairo") now applies only to the file-based devices
      as it is now possible (if very unusual) to build R with Cairo
      support for those but not for X11().
    * There is optional support for tracing the progress of
      loadNamespace() - see its help.
    * (Not Windows.)  l10n_info() reports an additional element, the
      name of the encoding as reported by the OS (which may differ from
      the encoding part (if any) of the result from
      Sys.getlocale("LC_CTYPE").
    * New function gregexec() which generalizes regexec() to find _all_
      disjoint matches and well as all substrings corresponding to
      parenthesized subexpressions of the given regular expression.
      (Contributed by Brodie Gaslam.)
    * New function charClass() in package utils to query the
      wide-character classification functions in use (such as
      iswprint).
    * The names of quantile()'s result no longer depend on the global
      getOption("digits"), but quantile() gets a new optional argument
      digits = 7 instead.
    * grep(), sub(), regexp and variants work considerably faster for
      long factors with few levels.  (Thanks to Michael Chirico's
      PR#18063.)
    * Provide grouping of x11() graphics windows within a window
      manager such as Gnome or Unity; thanks to a patch by Ivan Krylov
      posted to R-devel.
    * The split() method for class data.frame now allows the f argument
      to be specified as a formula.
    * sprintf now warns on arguments unused by the format string.
    * New palettes "Rocket" and "Mako" for hcl.colors() (approximating
      palettes of the same name from the 'viridisLite' package).
      Contributed by Achim Zeileis.
    * The base environment and its namespace are now locked (so one can
      no longer add bindings to these or remove from these).
    * Rterm handling of multi-byte characters has been improved,
      allowing use of such characters when supported by the current
      locale.
    * Rterm now accepts ALT+ +xxxxxxxx sequences to enter Unicode
      characters as hex digits.
    * Environment variable LC_ALL on Windows now takes precedence over
      LC_CTYPE and variables for other supported categories, matching
      the POSIX behaviour.
    * duplicated() and anyDuplicated() are now optimized for integer
      and real vectors that are known to be sorted via the ALTREP
      framework. Contributed by Gabriel Becker via PR#17993.
    GRAPHICS:
    * The graphics engine version, R_GE_version, has been bumped to 14
      and so packages that provide graphics devices should be
      reinstalled.
    * Graphics devices should now specify deviceVersion to indicate
      what version of the graphics engine they support.
    * Graphics devices can now specify deviceClip.  If TRUE, the
      graphics engine will never perform any clipping of output itself.
      The clipping that the graphics engine does perform (for both
      canClip = TRUE and canClip = FALSE) has been improved to avoid
      producing unnecessary artifacts in clipped output.
    * The grid package now allows gpar(fill) to be a linearGradient(),
      a radialGradient(), or a pattern().  The viewport(clip) can now
      also be a grob, which defines a clipping path, and there is a new
      viewport(mask) that can also be a grob, which defines a mask.
      These new features are only supported so far on the Cairo-based
      graphics devices and on the pdf() device.
    * (Not Windows.)  A warning is given when a Cairo-based type is
      specified for a png(), jpeg(), tiff() or bmp() device but Cairo
      is unsupported (so type = "Xlib" is tried instead).
    * grSoftVersion() now reports the versions of FreeType and
      FontConfig if they are used directly (not _via_ Pango), as is
      most commonly done on macOS.
    C-LEVEL FACILITIES:
    * The _standalone_ libRmath math library and R's C API now provide
      log1pexp() again as documented, and gain log1mexp().
    INSTALLATION on a UNIX-ALIKE:
    * configure checks for a program pkgconf if program pkg-config is
      not found.  These are now only looked for on the path (like
      almost all other programs) so if needed specify a full path to
      the command in PKG_CONFIG, for example in file config.site.
    * C99 function iswblank is required - it was last seen missing ca
      2003 so the workaround has been removed.
    * There are new configure options --with-internal-iswxxxxx,
    - -with-internal-towlower and --with-internal-wcwidth which allows
      the system functions for wide-character classification,
      case-switching and width (wcwidth and wcswidth) to be replaced by
      internal ones.  The first has long been used on macOS, AIX (and
      Windows) but this enables it to be unselected there and selected
      for other platforms (it is the new default on Solaris).  The
      second is new in this version of R and is selected by default on
      macOS and Solaris.  The third has long been the default and
      remains so as it contains customizations for East Asian
      languages.
      System versions of these functions are often minimally
      implemented (sometimes only for ASCII characters) and may not
      cover the full range of Unicode points: for example Solaris (and
      Windows) only cover the Basic Multilingual Plane.
    * Cairo installations without X11 are more likely to be detected by
      configure, when the file-based Cairo graphics devices will be
      available but not X11(type = "cairo").
    * There is a new configure option --with-static-cairo which is the
      default on macOS.  This should be used when only static cairo
      (and where relevant, Pango) libraries are available.
    * Cairo-based graphics devices on platforms without Pango but with
      FreeType/FontConfig will make use of the latter for font
      selection.
    LINK-TIME OPTIMIZATION on a UNIX-ALIKE:
    * Configuring with flag --enable-lto=R now also uses LTO when
      installing the recommended packages.
    * R CMD INSTALL and R CMD SHLIB have a new flag --use-LTO to use
      LTO when compiling code, for use with R configured with
    - -enable-lto=R.  For R configured with --enable-lto, they have
      the new flag --no-use-LTO.
      Packages can opt in or out of LTO compilation _via_ a UseLTO
      field in the DESCRIPTION file.  (As usual this can be overridden
      by the command-line flags.)
    BUILDING R on Windows:
    * for GCC >= 8, FC_LEN_T is defined in config.h and hence character
      lengths are passed from C to Fortran in _inter alia_ BLAS and
      LAPACK calls.
    * There is a new text file src/gnuwin32/README.compilation, which
      outlines how C/Fortran code compilation is organized and
      documents new features:
    * R can be built with Link-Time Optimization with a suitable
      compiler - doing so with GCC 9.2 showed several
      inconsistencies which have been corrected.
    * There is support for cross-compiling the C and Fortran code
      in R and standard packages on suitable (Linux) platforms.
      This is mainly intended to allow developers to test later
      versions of compilers - for example using GCC 9.2 or 10.x has
      detected issues that GCC 8.3 in Rtools40 does not.
    * There is experimental support for cross-building R packages
      with C, C++ and/or Fortran code.
    * The R installer can now be optionally built to support a single
      architecture (only 64-bit or only 32-bit).
    PACKAGE INSTALLATION:
    * The default C++ standard has been changed to C++14 where
      available (which it is on all currently checked platforms): if
      not (as before) C++11 is used if available otherwise C++ is not
      supported.
      Packages which specify C++11 will still be installed using C++11.
      C++14 compilers may give deprecation warnings, most often for
      std::random_shuffle (deprecated in C++14 and removed in C++17).
      Either specify C++11 (see 'Writing R Extensions') or modernize
      the code and if needed specify C++14.  The latter has been
      supported since R 3.4.0 so the package's DESCRIPTION would need
      to include something like
      Depends: R (>= 3.4)
    PACKAGE INSTALLATION on Windows:
    * R CMD INSTALL and R CMD SHLIB make use of their flag --use-LTO
      when the LTO_OPT make macro is set in file etc/${R_ARCH}/Makeconf
      or in a personal/site Makevars file.  (For details see 'Writing R
      Extensions' SS4.5.)
      This provides a valuable check on code consistency.  It does work
      with GCC 8.3 as in Rtools40, but that does not detect everything
      the CRAN checks with current GCC do.
    PACKAGE INSTALLATION on macOS:
    * The default personal library directory on builds with
    - -enable-aqua (including CRAN builds) now differs by CPU type,
      one of
      ~/Library/R/x86_64/x.y/library
      ~/Library/R/arm64/x.y/library
      This uses the CPU type R (and hence the packages) were built for,
      so when a x86_64 build of R is run under Rosetta emulation on an
      arm64 Mac, the first is used.
    UTILITIES:
    * R CMD check can now scan package functions for bogus return
      statements, which were possibly intended as return() calls (wish
      of PR#17180, patch by Sebastian Meyer). This check can be
      activated via the new environment variable
      _R_CHECK_BOGUS_RETURN_, true for --as-cran.
    * R CMD build omits tarballs and binaries of previous builds from
      the top-level package directory.  (PR#17828, patch by Sebastian
      Meyer.)
    * R CMD check now runs sanity checks on the use of LazyData, for
      example that a data directory is present and that
      LazyDataCompression is not specified without LazyData and has a
      documented value.  For packages with large LazyData databases
      without specifying LazyDataCompression, there is a reference to
      the code given in 'Writing R Extensions' SS1.1.6 to test the
      choice of compression (as in all the CRAN packages tested a
      non-default method was preferred).
    * R CMD build removes LazyData and LazyDataCompression fields from
      the DESCRIPTION file of packages without a data directory.
    ENCODING-RELATED CHANGES:
    * The parser now treats \Unnnnnnnn escapes larger than the upper
      limit for Unicode points (\U10FFFF) as an error as they cannot be
      represented by valid UTF-8.
      Where such escapes are used for outputting non-printable
      (including unassigned) characters, 6 hex digits are used (rather
      than 8 with leading zeros).  For clarity, braces are used, for
      example \U{0effff}.
    * The parser now looks for non-ASCII spaces on Solaris (as
      previously on most other OSes).
    * There are warnings (including from the parser) on the use of
      unpaired surrogate Unicode points such as \uD834.  (These cannot
      be converted to valid UTF-8.)
    * Functions nchar(), tolower(), toupper() and chartr() and those
      using regular expressions have more support for inputs with a
      marked Latin-1 encoding.
    * The character-classification functions used (by default) to
      replace the system iswxxxxx functions on Windows, macOS and AIX
      have been updated to Unicode 13.0.0.
      The character-width tables have been updated to include new
      assignments in Unicode 13.0.0.
    * The code for evaluating default (extended) regular expressions
      now uses the same character-classification functions as the rest
      of R (previously they differed on Windows, macOS and AIX).
    * There is a build-time option to replace the system's
      wide-character wctrans C function by tables shipped with R: use
      configure option --with-internal-towlower or (on Windows)
    - DUSE_RI18N_CASE in CFLAGS when building R.  This may be needed
      to allow tolower() and toupper() to work with Unicode characters
      beyond the Basic Multilingual Plane where not supported by system
      functions (e.g. on Solaris where it is the new default).
    * R is more careful when truncating UTF-8 and other multi-byte
      strings that are too long to be printed, passed to the system or
      libraries or placed into an internal buffer.  Truncation will no
      longer produce incomplete multibyte characters.
    DEPRECATED AND DEFUNCT:
    * Function plclust() from the package stats and
      package.dependencies(), pkgDepends(), getDepList(),
      installFoundDepends(), and vignetteDepends() from package tools
      are defunct.
    * Defunct functions checkNEWS() and readNEWS() from package tools
      and CRAN.packages() from utils have been removed.
    * R CMD config CXXCPP is defunct (it was deprecated in R 3.6.2).
    * parallel::detectCores() drops support for Irix (retired in 2013).
    * The LINPACK argument to chol.default(), chol2inv(),
      solve.default() and svd() has been defunct since R 3.1.0.  It was
      silently ignored up to R 4.0.3 but now gives an error.
    * Subsetting/indexing, such as ddd[*] or ddd$x on a DOTSXP
      (dot-dot-dot) object ddd has been disabled; it worked by accident
      only and was undocumented.
    BUG FIXES:
    * Many more C-level allocations (mainly by malloc and strdup) are
      checked for success with suitable alternative actions.
    * Bug fix for replayPlot(); this was turning off graphics engine
      display list recording if a recorded plot was replayed in the
      same session.  The impact of the bug became visible if resize the
      device after replay OR if attempted another savePlot() after
      replay (empty display list means empty screen on resize or empty
      saved plot).
    * R CMD check etc now warn when a package exports non-existing S4
      classes or methods, also in case of no "methods" presence.
      (Reported by Alex Bertram; reproducible example and patch by
      Sebastian Meyer in PR#16662.)
    * boxplot() now also accepts calls for labels such as ylab, the
      same as plot().  (Reported by Marius Hofert.)
    * The help page for xtabs() now correctly states that addNA is
      setting na.action = na.pass among others.  (Reported as PR#17770
      by Thomas Soeiro.)
    * The R CMD check <pkg> gives a longer and more comprehensible
      message when DESCRIPTION misses dependencies, e.g., in Imports:.
      (Thanks to the contributors of PR#17179.)
    * update.default() now calls the generic update() on the formula to
      work correctly for models with extended formulas.  (As reported
      and suggested by Neal Fultz in PR#17865.)
    * The horizontal position of leaves in a dendrogram is now correct
      also with center = FALSE.  (PR#14938, patch from Sebastian
      Meyer.)
    * all.equal.POSIXt() no longer warns about and subsequently ignores
      inconsistent "tzone" attributes, but describes the difference in
      its return value (PR#17277).  This check can be disabled _via_
      the new argument check.tzone = FALSE as suggested by Sebastian
      Meyer.
    * as.POSIXct() now populates the "tzone" attribute from its tz
      argument when x is a logical vector consisting entirely of NA
      values.
    * x[[2^31]] <- v now works.  (Thanks to the report and patch by
      Suharto Anggono in PR#17330.)
    * In log-scale graphics, axis() ticks and label positions are now
      computed more carefully and symmetrically in their range,
      typically providing _more_ ticks, fulfilling wishes in PR#17936.
      The change really corresponds to an improved axisTicks() (package
      grDevices), potentially influencing grid and lattice, for
      example.
    * qnorm(<very large negative>, log.p=TRUE) is now correct to at
      least five digits where it was catastrophically wrong,
      previously.
    * sum(df) and similar "Summary"- and "Math"-group member functions
      now work for data frames df with logical columns, notably also of
      zero rows.  (Reported to R-devel by Martin "b706".)
    * unsplit() had trouble with tibbles due to unsound use of rep(NA,
      len)-indexing, which should use NA_integer_ (Reported to R-devel
      by Mario Annau.)
    * pnorm(x, log.p = TRUE) underflows to -Inf slightly later.
    * show(<hidden S4 generic>) prints better and without quotes for
      non-hidden S4 generics.
    * read.table() and relatives treated an "NA" column name as missing
      when check.names = FALSE PR#18007.
    * Parsing strings containing UTF-16 surrogate pairs such as
      "\uD834\uDD1E" works better on some (uncommon) platforms.
      sprintf("%X", utf8ToInt("\uD834\uDD1E")) should now give "1D11E"
      on all platforms.
    * identical(x,y) is no longer true for differing DOTSXP objects,
      fixing PR#18032.
    * str() now works correctly for DOTSXP and related exotics, even
      when these are doomed.
      Additionally, it no longer fails for lists with a class and
      "irregular" method definitions such that e.g. lapply(*) will
      necessarily fail, as currently for different igraph objects.
    * Too long lines in environment files (e.g. Renviron) no longer
      crash R. This limit has been increased to 100,000 bytes.
      (PR#18001.)
    * There is a further workaround for FreeType giving incorrect
      italic font faces with cairo-based graphics devices on macOS.
    * add_datalist(*, force = TRUE) (from package tools) now actually
      updates an existing data/datalist file for new content.  (Thanks
      to a report and patch by Sebastian Meyer in PR#18048.)
    * cut.Date() and cut.POSIXt() could produce an empty last interval
      for breaks = "months" or breaks = "years".  (Reported as PR#18053
      by Christopher Carbone.)
    * Detection of the encoding of 'regular' macOS locales such as
      en_US (which is UTF-8) had been broken by a macOS change:
      fortunately these are now rarely used with en_US.UTF-8 being
      preferred.
    * sub() and gsub(pattern, repl, x, *) now keep attributes of x such
      as names() also when pattern is NA (PR#18079).
    * Time differences ("difftime" objects) get a replacement and a
      rep() method to keep "units" consistent.  (Thanks to a report and
      patch by Nicolas Bennett in PR#18066.)
    * The \RdOpts macro, setting defaults for \Sexpr options in an Rd
      file, had been ineffective since R 2.12.0: it now works again.
      (Thanks to a report and patch by Sebastian Meyer in PR#18073.)
    * mclapply and pvec no longer accidentally terminate parallel
      processes started before by mcparallel or related calls in
      package parallel (PR#18078).
    * grep and other functions for evaluating (extended) regular
      expressions handle in Unicode also strings not explicitly flagged
      UTF-8, but flagged native when running in UTF-8 locale.
    * Fixed a crash in fifo implementation on Windows (PR#18031).
    * Binary mode in fifo on Windows is now properly detected from
      argument open (PR#15600, PR#18031).
* Tue May 18 2021 Detlef Steuer <detlef.steuer@gmx.de>
  - improved spec file according to comments of dimstar in
    https://build.opensuse.org/request/show/892685
* Thu May 06 2021 Detlef Steuer <detlef.steuer@gmx.de>
  - To get in sync with d:l:R:autoCRAN the Matrix package's split
    in -devel was reversed.
* Wed Mar 31 2021 Detlef Steuer <detlef.steuer@gmx.de>
  - CHANGES IN R 4.0.5:
    BUG FIXES:
    * The change to the internal table in R 4.0.4 for iswprint has been
      reverted: it contained some errors in printability of 'East
    Asian' characters.
    * For packages using LazyData, R CMD build ignored the
    - -resave-data option and the BuildResaveData field of the
    DESCRIPTION file (in R versions 4.0.0 to 4.0.4).
* Mon Feb 15 2021 Detlef Steuer <detlef.steuer@gmx.de>
  - CHANGES IN R 4.0.4:
    NEW FEATURES:
    * File share/texmf/tex/latex/jss.cls has been updated to work with
      LaTeX versions since Oct 2020.
    * Unicode character width tables (as used by nchar(, type = "w"))
      have been updated to Unicode 12.1 by Brodie Gaslam (PR#17781),
      including many emoji.
    * The internal table for iswprint (used on Windows, macOS and AIX)
      has been updated to include many recent Unicode characters.
    INSTALLATION on a UNIX-ALIKE:
    * If an external BLAS is specified by --with-blas=foo or _via_
      environment variable BLAS_LIBS is not found, this is now a
      configuration error.  The previous behaviour was not clear from
      the documentation: it was to continue the search as if
    - -with-blas=yes was specified.
    BUG FIXES:
    * all.equal(x,y) now "sees" the two different NAs in factors,
      thanks to Bill Dunlap and others in PR#17897.
    * (~ NULL)[1] and similar formula subsetting now works, thanks to a
      report and patch by Henrik Bengtsson in PR#17935.  Additionally,
      subsetting leaving an empty formula now works too, thanks to
      suggestions by Suharto Anggono.
    * .traceback(n) keeps source references again, as before R 4.0.0,
      fixing a regression; introduced by the PR#17580, reported
      including two patch proposals by Brodie Gaslam.
    * unlist(plst, recursive=FALSE) no longer drops content for
      pairlists with list components, thanks to the report and patch by
      Suharto Anggono in PR#17950.
    * iconvlist() now also works on MUSL based (Linux) systems, from a
      report and patch suggestion by Wesley Chan in PR#17970.
    * round() and signif() no longer tolerate wrong argument names,
      notably in 1-argument calls; reported by Shane Mueller on R-devel
      (mailing list); later reported as PR#17976.
    * .Machine has longdouble.* elements only if
      capabilities("long.double") is true, as documented.  (Previously
      they were included if the platform had long double identical to
      double, as ARM does.)
    * p.adjust(numeric(), n=0) now works, fixing PR#18002.
    * identical(x,y) no longer prints "Unknown Type .." for typeof(x)
      == "..." objects.
    * Fix (auto-)print()ing of named complex vectors, see PR#17868 and
      PR#18019.
    * all.equal(<language>, <...>) now works, fixing PR#18029.
    * as.data.frame.list(L, row.names=NULL) now behaves in line with
      data.frame(), disregarding names of components of L, fixing
      PR#18034, reported by Kevin Tappe.
    * checkRdaFiles(ff)$version is now correct also when ff contains
      files of different versions, thanks to a report and patch from
      Sebastian Meyer in PR#18041.
    * macOS: Quartz device live drawing could fail (no plot is shown)
      if the system changes the drawing context after view update
      (often the case since macOS Big Sur). System log may show
      "CGContextDelegateCreateForContext: invalid context" error.
* Sat Oct 10 2020 Detlef Steuer <detlef.steuer@gmx.de>
  - CHANGES IN R 4.0.3:
    NEW FEATURES:
    * On platforms using configure option --with-internal-tzcode,
      additional values "internal" and (on macOS only) "macOS" are
      accepted for the environment variable TZDIR.  (See ?TZDIR.)
      On macOS, "macOS" is used by default if the system timezone
      database is a newer version than that in the R installation.
    * When install.packages(type = "source") fails to find a package in
      a repository it mentions package versions which are excluded by
      their R version requirement and links to hints on why a package
      might not be found.
    * The default value for options("timeout") can be set from
      enviromnent variable R_DEFAULT_INTERNET_TIMEOUT, still defaulting
      to 60 (seconds) if that is not set or invalid.
      This may be needed when child R processes are doing downloads,
      for example during the installation of source packages which
      download jars or other forms of data.
    LINK-TIME OPTIMIZATION on a UNIX-ALIKE:
    * There is now support for parallelized Link-Time Optimization
      (LTO) with GCC and for 'thin' LTO with clang _via_ setting the
      LTO macro.
    * There is support for setting a different LTO flag for the Fortran
      compiler, including to empty when mixing clang and gfortran (as
      on macOS).  See file config.site.
    * There is a new LTO_LD macro to set linker options for LTO
      compilation, for example to select an alternative linker or to
      parallelize thin LTO.
    DEPRECATED AND DEFUNCT:
    * The LINPACK argument to chol.default(), chol2inv(),
      solve.default() and svd() has been defunct since R 3.1.0.  Using
      it now gives a warning which will become an error in R 4.1.0.
    BUG FIXES:
    * The code mitigating stack overflow with PCRE regexps on very long
      strings is enabled for PCRE2 < 10.30 also when JIT is enabled,
      since stack overflows have been seen in that case.
    * Fix to correctly show the group labels in dotchart() (which where
      lost in the ylab improvement for R 4.0.0).
    * addmargins(*, ..) now also works when fn() is a local function,
      thanks to bug report and patch PR#17124 from Alex Bertram.
    * rank(x) and hence sort(x) now work when x is an object (as per
      is.object(x)) of type "raw" _and_ provides a valid `[` method,
      e.g., for gmp::as.bigz(.) numbers.
    * chisq.test(*, simulate.p.value=TRUE) and r2dtable() now work
      correctly for large table entries (in the millions).  Reported by
      Sebastian Meyer and investigated by more helpers in PR#16184.
    * Low-level socket read/write operations have been fixed to
      correctly signal communication errors. Previously, such errors
      could lead to a segfault due to invalid memory access. Reported
      and debugged by Dmitriy Selivanov in PR#17850.
    * quantile(x, pr) works more consistently for pr values slightly
      outside [0,1], thanks to Suharto Anggono's PR#17891.
      Further, quantile(x, prN, names=FALSE) now works even when prN
      contains NAs, thanks to Anggono's PR#17892.  Ditto for ordered
      factors or Date objects when type = 1 or 3, thanks to PR#17899.
    * Libcurl-based internet access, including curlGetHeaders(), was
      not respecting the "timeout" option.  If this causes
      unanticipated timeouts, consider increasing the default by
      setting R_DEFAULT_INTERNET_TIMEOUT.
    * as.Date(<char>) now also works with an initial "", thanks to
      Michael Chirico's PR#17909.
    * isS3stdGeneric(f) now detects an S3 generic also when it it is
      trace()d, thanks to Gabe Becker's PR#17917.
    * R_allocLD() has been fixed to return memory aligned for long
      double type PR#16534.
    * fisher.test() no longer segfaults when called again after its
      internal stack has been exceeded PR#17904.
    * Accessing a long vector represented by a compact integer sequence
      no longer segfaults (reported and debugged by Hugh Parsonage).
    * duplicated() now works also for strings with multiple encodings
      inside a single vector PR#17809.
    * phyper(11, 15, 0, 12, log.p=TRUE) no longer gives NaN; reported
      as PR#17271 by Alexey Stukalov.
    * Fix incorrect calculation in logLik.nls() PR#16100, patch from
      Sebastian Meyer.
    * A very old bug could cause a segfault in model.matrix() when
      terms involved logical variables.  Part of PR#17879.
    * model.frame.default() allowed data = 1, leading to involuntary
      variable capture (rest of PR#17879).
    * tar() no longer skips non-directory files, thanks to a patch by
      Sebastian Meyer, fixing the remaining part of PR#16716.

  - CHANGES IN R 4.0.2:
    UTILITIES:
    * R CMD check skips vignette re-building (with a warning) if the
      VignetteBuilder package(s) are not available.
    BUG FIXES:
    * Paths with non-ASCII characters caused problems for package
      loading on Windows PR#17833.
    * Using tcltk widgets no longer crashes R on Windows.
    * source(*, echo=TRUE) no longer fails in some cases with empty
      lines; reported by Bill Dunlap in PR#17769.
    * on.exit() now correctly matches named arguments, thanks to
      PR#17815 (including patch) by Brodie Gaslam.
    * regexpr(*, perl=TRUE) no longer returns incorrect positions into
      text containing characters outside of the Unicode Basic
      Multilingual Plane on Windows.
* Sat Jun 06 2020 Detlef Steuer <detlef.steuer@gmx.de>
  - CHANGES IN R 4.0.1:
    NEW FEATURES:
    * paste() and paste0() gain a new optional argument recycle0.  When
      set to true, zero-length arguments are recycled leading to
      character(0) after the sep-concatenation, i.e., to the empty
      string "" if collapse is a string and to the zero-length value
      character(0) when collapse = NULL.
      A package whose code uses this should depend on R (>= 4.0.1).
    * The summary(<warnings>) method now maps the counts correctly to
      the warning messages.
    BUG FIXES:
    * aov(frml, ...) now also works where the formula deparses to more
      than 500 characters, thanks to a report and patch proposal by Jan
      Hauffa.
    * Fix a dozen places (code, examples) as Sys.setlocale() returns
      the new rather than the previous setting.
    * Fix for adding two complex grid units via sum().  Thanks to Gu
      Zuguang for the report and Thomas Lin Pedersen for the patch.
    * Fix parallel::mclapply(..., mc.preschedule=FALSE) to handle raw
      vector results correctly. PR#17779
    * Computing the base value, i.e., 2, "everywhere", now uses
      FLT_RADIX, as the original machar code looped indefinitely on the
      ppc64 architecture for the longdouble case.
    * In R 4.0.0, sort.list(x) when is.object(x) was true, e.g., for x
      <- I(letters), was accidentally using method = "radix".
      Consequently, e.g., merge(<data.frame>) was much slower than
      previously; reported in PR#17794.
    * plot(y ~ x, ylab = quote(y[i])) now works, as e.g., for xlab;
      related to PR#10525.
    * parallel::detect.cores(all.tests = TRUE) tries a matching OS name
      before the other tests (which were intended only for unknown
      OSes).
    * Parse data for raw strings is now recorded correctly. Reported by
      Gabor Csardi.
* Fri Apr 24 2020 Detlef Steuer <detlef.steuer@gmx.de>
  - CHANGES IN 4.0.0:
    SIGNIFICANT USER-VISIBLE CHANGES:
    * Packages need to be (re-)installed under this version (4.0.0) of
      R.
    * matrix objects now also inherit from class "array", so e.g.,
      class(diag(1)) is c("matrix", "array").  This invalidates code
      incorrectly assuming that class(matrix_obj)) has length one.
      S3 methods for class "array" are now dispatched for matrix
      objects.
    * There is a new syntax for specifying _raw_ character constants
      similar to the one used in C++: r"(...)" with ... any character
      sequence not containing the sequence )".  This makes it easier to
      write strings that contain backslashes or both single and double
      quotes.  For more details see ?Quotes.
    * R now uses a stringsAsFactors = FALSE default, and hence by
      default no longer converts strings to factors in calls to
      data.frame() and read.table().
      A large number of packages relied on the previous behaviour and
      so have needed/will need updating.
    * The plot() S3 generic function is now in package base rather than
      package graphics, as it is reasonable to have methods that do not
      use the graphics package.  The generic is currently re-exported
      from the graphics namespace to allow packages importing it from
      there to continue working, but this may change in future.
      Packages which define S4 generics for plot() should be
      re-installed and package code using such generics from other
      packages needs to ensure that they are imported rather than rely
      on their being looked for on the search path (as in a namespace,
      the base namespace has precedence over the search path).
    REFERENCE COUNTING:
    * Reference counting is now used instead of the NAMED mechanism for
      determining when objects can be safely mutated in base C code.
      This reduces the need for copying in some cases and should allow
      further optimizations in the future.  It should help make the
      internal code easier to maintain.
      This change is expected to have almost no impact on packages
      using supported coding practices in their C/C++ code.
    MIGRATION TO PCRE2:
    * This version of R is built against the PCRE2 library for
      Perl-like regular expressions, if available.  (On non-Windows
      platforms PCRE1 can optionally be used if PCRE2 is not available
      at build time.)  The version of PCRE in use can be obtained _via_
      extSoftVersion(): PCRE1 (formerly known as 'PCRE') has versions
      <= 8, PCRE2 versions >= 10.
    * Making PCRE2 available when building R from source is strongly
      recommended (preferably version 10.30 or later) as PCRE1 is no
      longer developed: version 8.44 is 'likely to be the final
      release'.
    * PCRE2 reports errors for some regular expressions that were
      accepted by PCRE1.  A hyphen now has to be escaped in a character
      class to be interpreted as a literal (unless first or last in the
      class definition).  \R, \B and \X are no longer allowed in
      character classes (PCRE1 treated these as literals).
    * Option PCRE_study is no longer used with PCRE2, and is reported
      as FALSE when that is in use.
    NEW FEATURES:
    * assertError() and assertWarning() (in package tools) can now
      check for _specific_ error or warning classes _via_ the new
      optional second argument classes (which is not back compatible
      with previous use of an unnamed second argument).
    * DF2formula(), the utility for the data frame method of formula(),
      now works without parsing and explicit evaluation, starting from
      Suharto Anggono's suggestion in PR#17555.
    * approxfun() and approx() gain a new argument na.rm defaulting to
      true.  If set to false, missing y values now propagate into the
      interpolated values.
    * Long vectors are now supported as the seq argument of a for()
      loop.
    * str(x) gets a new deparse.lines option with a default to speed it
      up when x is a large call object.
    * The internal traceback object produced when an error is signalled
      (.Traceback), now contains the calls rather than the _deparse()d_
      calls, deferring the deparsing to the user-level functions
      .traceback() and traceback().  This fulfils the wish of PR#17580,
      reported including two patch proposals by Brodie Gaslam.
    * data.matrix() now converts character columns to factors and from
      this to integers.
    * package.skeleton() now explicitly lists all exports in the
      NAMESPACE file.
    * New function .S3method() to register S3 methods in R scripts.
    * file.path() has some support for file paths not in the session
      encoding, e.g. with UTF-8 inputs in a non-UTF-8 locale the output
      is marked as UTF-8.
    * Most functions with file-path inputs will give an explicit error
      if a file-path input in a marked encoding cannot be translated
      (to the native encoding or in some cases on Windows to UTF-8),
      rather than translate to a different file path using escapes.
      Some (such as dir.exists(), file.exists(), file.access(),
      file.info(), list.files(), normalizePath() and path.expand())
      treat this like any other non-existent file, often with a
      warning.
    * There is a new help document accessed by help("file path
      encoding") detailing how file paths with marked encodings are
      handled.
    * New function list2DF() for creating data frames from lists of
      variables.
    * iconv() has a new option sub = "Unicode" to translate UTF-8 input
      invalid in the to encoding using <U+xxxx> escapes.
    * There is a new function infoRDS() providing information about the
      serialization format of a serialized object.
    * S3 method lookup now by default skips the elements of the search
      path between the global and base environments.
    * Added an argument add_datalist(*, small.size = 0) to allow the
      creation of a data/datalist file even when the total size of the
      data sets is small.
    * The backquote function bquote() has a new argument splice to
      enable splicing a computed list of values into an expression,
      like ,@ in LISP's backquote.
    * The formula interface to t.test() and wilcox.test() has been
      extended to handle one-sample and paired tests.
    * The palette() function has a new default set of colours (which
      are less saturated and have better accessibility properties).
      There are also some new built-in palettes, which are listed by
      the new palette.pals() function.  These include the old default
      palette under the name "R3". Finally, the new palette.colors()
      function allows a subset of colours to be selected from any of
      the built-in palettes.
    * n2mfrow() gains an option asp = 1 to specify the aspect ratio,
      fulfilling the wish and extending the proposal of Michael Chirico
      in PR#17648.
    * For head(x, n) and tail() the default and other S3 methods
      notably for _vector_ n, e.g. to get a "corner" of a matrix, has
      been extended to array's of higher dimension thanks to the patch
      proposal by Gabe Becker in PR#17652.  Consequently, optional
      argument addrownums is deprecated and replaced by the (more
      general) argument keepnums.  An invalid second argument n now
      leads to typically more easily readable error messages.
    * New function .class2() provides the full character vector of
      class names used for S3 method dispatch.
    * Printing methods(..) now uses a new format() method.
    * sort.list(x) now works for non-atomic objects x and method =
      "auto" (the default) or "radix" in cases order(x) works.
    * Where they are available, writeBin() allows long vectors.
    * New function deparse1() produces one string, wrapping deparse(),
      to be used typically in deparse1(substitute(*)), e.g., to fix
      PR#17671.
    * wilcox.test() enhancements: In the (non-paired) two-sample case,
      Inf values are treated as very large for robustness consistency.
      If exact computations are used, the result now has "exact" in the
      method element of its return value.  New arguments tol.root and
      digits.rank where the latter may be used for stability to treat
      very close numbers as ties.
    * readBin() and writeBin() now report an error for an invalid
      endian value.  The affected code needs to be fixed with care as
      the old undocumented behavior was to swap endian-ness in such
      cases.
    * sequence() is now an S3 generic with an internally implemented
      default method, and gains arguments to generate more complex
      sequences.  Based on code from the S4Vectors Bioconductor package
      and the advice of Herv'e Pag`es.
    * print()'s default method and many other methods (by calling the
      default eventually and passing ...) now make use of a new
      optional width argument, avoiding the need for the user to set
      and reset options("width").
    * memDecompress() supports the RFC 1952 format (e.g. in-memory
      copies of gzip-compressed files) as well as RFC 1950.
    * memCompress() and memDecompress() support long raw vectors for
      types "gzip" and "zx".
    * sweep() and slice.index() can now use names of dimnames for their
      MARGIN argument (apply has had this for almost a decade).
    * New function proportions() and marginSums(). These should replace
      the unfortunately named prop.table() and margin.table(). They are
      drop-in replacements, but also add named-margin functionality.
      The old function names are retained as aliases for
      back-compatibility.
    * Functions rbinom(), rgeom(), rhyper(), rpois(), rnbinom(),
      rsignrank() and rwilcox() which have returned integer since R
      3.0.0 and hence NA when the numbers would have been outside the
      integer range, now return double vectors (without NAs, typically)
      in these cases.
    * matplot(x,y) (and hence matlines() and matpoints()) now call the
      corresponding methods of plot() and lines(), e.g, when x is a
      "Date" or "POSIXct" object; prompted by Spencer Graves'
      suggestion.
    * stopifnot() now allows customizing error messages via argument
      names, thanks to a patch proposal by Neal Fultz in PR#17688.
    * unlink() gains a new argument expand to disable wildcard and
      tilde expansion.  Elements of x of value "~" are now ignored.
    * mle() in the stats4 package has had its interface extended so
      that arguments to the negative log-likelihood function can be one
      or more vectors, with similar conventions applying to bounds,
      start values, and parameter values to be kept fixed.  This
      required a minor extension to class "mle", so saved objects from
      earlier versions may need to be recomputed.
    * The default for pdf() is now useDingbats = FALSE.
    * The default fill colour for hist() and boxplot() is now col =
      "lightgray".
    * The default order of the levels on the y-axis for spineplot() and
      cdplot() has been reversed.
    * If the R_ALWAYS_INSTALL_TESTS environment variable is set to a
      true value, R CMD INSTALL behaves as if the --install-tests
      option is always specified. Thanks to Reinhold Koch for the
      suggestion.
    * New function R_user_dir() in package tools suggests paths
      appropriate for storing R-related user-specific data,
      configuration and cache files.
    * capabilities() gains a new logical option Xchk to avoid warnings
      about X11-related capabilities.
    * The internal implementation of grid units has changed, but the
      only visible effects at user-level should be
    * a slightly different print format for some units (especially
      unit arithmetic),
    * faster performance (for unit operations) and
    * two new functions unitType() and unit.psum().
      Based on code contributed by Thomas Lin Pedersen.
    * When internal dispatch for rep.int() and rep_len() fails, there
      is an attempt to dispatch on the equivalent call to rep().
    * Object .Machine now contains new longdouble.* entries (when R
      uses long doubles internally).
    * news() has been enhanced to cover the news on R 3.x and 2.x.
    * For consistency, N <- NULL; N[[1]] <- val now turns N into a list
      also when val) has length one.  This enables dimnames(r1)[[1]] <-
      "R1" for a 1-row matrix r1, fixing PR#17719 reported by Serguei
      Sokol.
    * deparse(..), dump(..), and dput(x, control = "all") now include
      control option "digits17" which typically ensures 1:1
      invertibility.  New option control = "exact" ensures numeric
      exact invertibility via "hexDigits".
    * When loading data sets via read.table(), data() now uses
      LC_COLLATE=C to ensure locale-independent results for possible
      string-to-factor conversions.
    * A server socket connection, a new connection type representing a
      listening server socket, is created via serverSocket() and can
      accept multiple socket connections via socketAccept().
    * New function socketTimeout() changes the connection timeout of a
      socket connection.
    * The time needed to start a homogeneous PSOCK cluster on localhost
      with many nodes has been significantly reduced (package
      parallel).
    * New globalCallingHandlers() function to establish global
      condition handlers.  This allows registering default handlers for
      specific condition classes. Developed in collaboration with
      Lionel Henry.
    * New function tryInvokeRestart() to invoke a specified restart if
      one is available and return without signaling an error if no such
      restart is found.  Contributed by Lionel Henry in PR#17598.
    * str(x) now shows the length of attributes in some cases for a
      data frame x.
    * Rprof() gains a new argument filter.callframes to request that
      intervening call frames due to lazy evaluation or explicit eval()
      calls be omitted from the recorded profile data.  Contributed by
      Lionel Henry in PR#17595.
    * The handling of ${FOO-bar} and ${FOO:-bar} in Renviron files now
      follows POSIX shells (at least on a Unix-alike), so the first
      treats empty environment variables as set and the second does
      not.  Previously both ignored empty variables.  There are several
      uses of the first form in etc/Renviron.
    * New classes argument for suppressWarnings() and
      suppressMessages() to selectively suppress only warnings or
      messages that inherit from particular classes.  Based on patch
      from Lionel Henry submitted with PR#17619.
    * New function activeBindingFunction() retrieves the function of an
      active binding.
    * New "cairoFT" and "pango" components in the output of
      grSoftVersion().
    * New argument symbolfamily in cairo-based graphics devices and new
      function cairoSymbolFont() that can be used to provide the value
      for that argument.
    Windows:
    * Rterm now works also when invoked from MSYS2 terminals.  Line
      editing is possible when command winpty is installed.
    * normalizePath() now resolves symbolic links and normalizes case
      of long names of path elements in case-insensitive folders
      (PR#17165).
    * md5sum() supports UTF-8 file names with characters that cannot be
      translated to the native encoding (PR#17633).
    * Rterm gains a new option --workspace to specify the workspace to
      be restored.  This allows equals to be part of the name when
      opening _via_ Windows file associations (reported by Christian
      Asseburg).
    * Rterm now accepts ALT+xxx sequences also with NumLock on.  Tilde
      can be pasted with an Italian keyboard (PR#17679).
    * R falls back to copying when junction creation fails during
      package checking (patch from Duncan Murdoch).
    DEPRECATED AND DEFUNCT:
    * Make macro F77_VISIBILITY has been removed and replaced by
      F_VISIBILITY.
    * Make macros F77, FCPIFCPLAGS and SHLIB_OPENMP_FCFLAGS have been
      removed and replaced by FC, FPICFLAGS and SHLIB_OPENMP_FFLAGS
      respectively.  (Most make programs will set F77 to the value of
      FC, which is set for package compilation.  But portable code
      should not rely on this.)
    * The deprecated support for specifying C++98 for package
      installation has been removed.
    * R CMD config no longer knows about the unused settings F77 and
      FCPIFCPLAGS, nor CXX98 and similar.
    * Either PCRE2 or PCRE1 >= 8.32 (Nov 2012) is required: the
      deprecated provision for 8.20-8.31 has been removed.
    * Defunct functions mem.limits(), .readRDS(),
      .saveRDS(),..find.package(), and .path.package() from package
      base and allGenerics(), getAccess(), getAllMethods(),
      getClassName(), getClassPackage(), getExtends(), getProperties(),
      getPrototype(), getSubclasses(), getVirtual(), mlistMetaName(),
      removeMethodsObject(), seemsS4Object(), traceOff(), and traceOn()
      from methods have been removed.
    C-LEVEL FACILITIES:
    * installChar is now remapped in Rinternals.h to installTrChar, of
      which it has been a wrapper since R 3.6.0.  Neither are part of
      the API, but packages using installChar can replace it if they
      depend on R >= 3.6.2.
    * Header R_ext/Print.h defines R_USE_C99_IN_CXX and hence exposes
      Rvprintf and REvprintf if used with a C++11 (or later) compiler.
    * There are new Fortran subroutines dblepr1, realpr1 and intpr1 to
      print a scalar variable (gfortran 10 enforces the distinction
      between scalars and length-one arrays).  Also labelpr to print
      just a label.
    * R_withCallingErrorHandler is now available for establishing a
      calling handler in C code for conditions inheriting from class
      error.
    INSTALLATION on a UNIX-ALIKE:
    * User-set DEFS (e.g., in config.site) is now used for compiling
      packages (including base packages).
    * There is a new variant option --enable-lto=check for checking
      consistency of BLAS/LAPACK/LINPACK calls - see 'Writing R
      Extensions'.
    * A C++ compiler default is set only if the C++11 standard is
      supported: it no longer falls back to C++98.
    * PCRE2 is used if available.  To make use of PCRE1 if PCRE2 is
      unavailable, configure with option --with-pcre1.
    * The minimum required version of libcurl is now 7.28.0 (Oct 2012).
    * New make target distcheck checks
    * R can be rebuilt from the tarball created by make dist,
    * the build from the tarball passes make check-all,
    * the build installs and uninstalls,
    * the source files are properly cleaned by make distclean.
    UTILITIES:
    * R --help now mentions the option --no-echo (renamed from --slave)
      and its previously undocumented short form -s.
    * R CMD check now optionally checks configure and cleanup scripts
      for non-Bourne-shell code ('bashisms').
    * R CMD check --as-cran now runs \donttest examples (which are run
      by example()) instead of instructing the tester to do so.  This
      can be temporarily circumvented during development by setting
      environment variable _R_CHECK_DONTTEST_EXAMPLES_ to a false
      value.
    PACKAGE INSTALLATION:
    * There is the beginnings of support for the recently approved
      C++20 standard, specified analogously to C++14 and C++17.  There
      is currently only limited support for this in compilers, with
      flags such as -std=c++20 and -std=c++2a.  For the time being the
      configure test is of accepting one of these flags and compiling
      C++17 code.
    BUG FIXES:
    * formula(x) with length(x) > 1 character vectors, is deprecated
      now.  Such use has been rare, and has 'worked' as expected in
      some cases only.  In other cases, wrong x have silently been
      truncated, not detecting previous errors.
    * Long-standing issue where the X11 device could lose events
      shortly after startup has been addressed (PR#16702).
    * The data.frame method for rbind() no longer drops <NA> levels
      from factor columns by default (PR#17562).
    * available.packages() and hence install.packages() now pass their
      ... argument to download.file(), fulfilling the wish of PR#17532;
      subsequently, available.packages() gets new argument quiet,
      solving PR#17573.
    * stopifnot() gets new argument exprObject to allow an R object of
      class expression (or other 'language') to work more consistently,
      thanks to suggestions by Suharto Anggono.
    * conformMethod() now works correctly in cases containing a "&&
      logic" bug, reported by Henrik Bengtsson.  It now creates methods
      with "missing" entries in the signature.  Consequently,
      rematchDefinition() is amended to use appropriate .local() calls
      with named arguments where needed.
    * format.default(*, scientific = FALSE) now corresponds to a
      practically most extreme options(scipen = n) setting rather than
      arbitrary n = 100.
    * format(as.symbol("foo")) now works (returning "foo").
    * postscript(.., title = *) now signals an error when the title
      string contains a character which would produce corrupt
      PostScript, thanks to PR#17607 by Daisuko Ogawa.
    * Certain Ops (notably comparison such as ==) now also work for
      0-length data frames, after reports by Hilmar Berger.
    * methods(class = class(glm(..))) now warns more usefully and only
      once.
    * write.dcf() no longer mangles field names (PR#17589).
    * Primitive replacement functions no longer mutate a referenced
      first argument when used outside of a complex assignment context.
    * A better error message for contour(*, levels = Inf).
    * The return value of contourLines() is no longer invisible().
    * The Fortran code for calculating the coefficients component in
      lm.influence() was very inefficient. It has (for now) been
      replaced with much faster R code (PR#17624).
    * cm.colors(n) _etc_ no longer append the code for alpha = 1, "FF",
      to all colors.  Hence all eight *.colors() functions and
      rainbow() behave consistently and have the same non-explicit
      default (PR#17659).
    * dnorm had a problematic corner case with sd == -Inf or negative
      sd which was not flagged as an error in all cases. Thanks to
      Stephen D. Weigand for reporting and Wang Jiefei for analyzing
      this; similar change has been made in dlnorm().
    * The optional iter.smooth argument of plot.lm(), (the plot()
      method for lm and glm fits) now defaults to 0 for all glm fits.
      Especially for binary observations with high or low fitted
      probabilities, this effectively deleted all observations of 1 or
      0.  Also, the type of residuals used in the glm case has been
      switched to "pearson" since deviance residuals do not in general
      have approximately zero mean.
    * In plot.lm, Cook's distance was computed from unweighted
      residuals, leading to inconsistencies.  Replaced with usual
      weighted version. (PR#16056)
    * Time-series ts(*, start, end, frequency) with fractional
      frequency are supported more consistently; thanks to a report
      from Johann Kleinbub and analysis and patch by Duncan Murdoch in
      PR#17669.
    * In case of errors mcmapply() now preserves attributes of returned
      "try-error" objects and avoids simplification, overriding
      SIMPLIFY to FALSE. (PR#17653)
    * as.difftime() gets new optional tz = "UTC" argument which should
      fix behaviour during daylight-savings-changeover days, fixing
      PR#16764, thanks to proposals and analysis by Johannes Ranke and
      Kirill M"uller.
    * round() does a better job of rounding _"to nearest"_ by
      _measuring_ and _"to even"_; thanks to a careful algorithm
      originally prompted by the report from Adam Wheeler and then
      others, in PR#17668.
      round(x, dig) for _negative_ digits is much more rational now,
      notably for large |dig|.
    * Inheritance information on S4 classes is maintained more
      consistently, particularly in the case of class unions (in part
      due to PR#17596 and a report from Ezra Tucker).
    * is() behaves more robustly when its argument class2 is a
      classRepresentation object.
    * The warning message when attempting to export an nonexistent
      class is now more readable; thanks to Thierry Onkelinx for
      recognizing the problem.
    * choose() misbehaved in corner cases where it switched n - k for k
      and n was only _nearly_ integer (report from Erik Scott Wright).
    * mle() in the stats4 package had problems combining use of box
      constraints and fixed starting values (in particular, confidence
      intervals were affected).
    * Operator ? now has lower precedence than = to work as documented,
      so = behaves like <- in help expressions (PR#16710).
    * smoothEnds(x) now returns integer type in _both_ cases when x is
      integer, thanks to a report and proposal by Bill Dunlap PR#17693.
    * The methods package does a better job of tracking inheritance
      relationships across packages.
    * norm(diag(c(1, NA)), "2") now works.
    * subset() had problems with 0-col dataframes (reported by Bill
      Dunlap, PR#17721).
    * Several cases of integer overflow detected by the 'undefined
      behaviour sanitizer' of clang 10 have been circumvented.  One in
      rhyper() may change the generated value for large input values.
    * dotchart() now places the y-axis label (ylab) much better, not
      overplotting labels, thanks to a report and suggestion by Alexey
      Shipunov.
    * A rare C-level array overflow in chull() has been worked around.
    * Some invalid specifications of the day-of-the-year (_via_ %j,
      e.g. day 366 in 2017) or week plus day-of-the-week are now
      detected by strptime().  They now return NA but give a warning as
      they may have given random results or corrupted memory in earlier
      versions of R.
    * socketConnection(server = FALSE) now respects the connection
      timeout also on Linux.
    * socketConnection(server = FALSE) no longer leaks a connection
      that is available right away without waiting (e.g. on localhost).
    * Socket connections are now robust against spurious readability
      and spurious availability of an incoming connection.
    * blocking = FALSE is now respected also on the server side of a
      socket connection, allowing non-blocking read operations.
    * anova.glm() and anova.glmlist() computed incorrect score (Rao)
      tests in no-intercept cases. (Andr'e Gillibert, PR#17734)
    * summaryRprof() now should work correctly for the Rprof(*,
      memory.profiling=TRUE) case with small chunk size (and "tseries"
      or similar) thanks to a patch proposal by Benjamin Tyner, in
      PR#15886.
    * xgettext() ignores strings passed to ngettext(), since the latter
      is handled by xngettext(). Thanks to Daniele Medri for the report
      and all the recent work he has done on the Italian translations.
    * data(package = "P") for P in base and stats no longer reports the
      data sets from package datasets (which it did for back
      compatibility for 16 years), fixing PR#17730.
    * x[[Inf]] (returning NULL) no longer leads to undefined behavior,
      thanks to a report by Kirill M"uller in PR#17756.  Further,
      x[[-Inf]] and x[[-n]] now give more helpful error messages.
    * Gamma() family sometimes had trouble storing link name PR#15891
    BUG FIXES (Windows):
    * Sys.glob() now supports all characters from the Unicode Basic
      Multilingual Plane, no longer corrupting some (less commonly
      used) characters (PR#17638).
    * Rterm now correctly displays multi-byte-coded characters
      representable in the current native encoding (at least on Windows
      10 they were sometimes omitted, PR#17632).
    * scan() issues with UTF-8 data when running in a DBCS locale have
      been resolved (PR#16520, PR#16584).
    * RTerm now accepts enhanced/arrow keys also with ConPTY.
    * R can can now be started _via_ the launcher icon in a user
      documents directory whose path is not representable in the system
      encoding.
    * socketConnection(server = FALSE) now returns instantly also on
      Windows when connection failure is signalled.
    * Problems with UTF-16 surrogate pairs have been fixed in several
      functions, including tolower() and toupper() (PR#17645).

  - CHANGES IN R 3.6.3:
    NEW FEATURES:
    * The included LAPACK has been updated to version 3.9.0 (for the
      included routines, just bug fixes).
    BUG FIXES:
    * Fixed a C level integer overflow in rhyper(); reported by
      Benjamin Tyner in PR#17694.
    * Uses of url(gzcon(.)) needing to extend buffer size have failed
      (with HTTP/2 servers), reported by G'abor Cs'ardi.
    * predict(loess(..), se=TRUE) now errors out (instead of
      seg.faulting etc) for large sample sizes, thanks to a report and
      patch by Benjamin Tyner in PR#17121.
    * tools:assertCondition(., "error") and hence assertError() no
      longer return errors twice (invisibly).
    * update(form, new) in the case of a long new formula sometimes
      wrongly eliminated the intercept from form, or (more rarely)
      added a garbage term (or seg.faulted !); the fix happened by
      simplifying the C-level logic of terms.formula().  Reported by
      Mathias Amb"uhl in PR#16326.
    * The error message from stopifnot(.., <error producing call>)
      again contains the full "stopifnot(.......)" call: Its attempted
      suppression did not work consistently.
    * On Windows, download.file(., , "wininet", headers=character())
      would fail; reported with patch proposal by Kevin Ushey in
      PR#17710.
* Mon Jan 20 2020 Dan Čermák <dcermak@suse.com>
  - Don't mark %{_libdir}/R/doc as %doc:
    This causes issues for rstudio, which requires the directory %{_libdir}/R/doc
    to exist, but the directory is not present if libzypp is configured to omit
    documentation.
* Thu Dec 12 2019 Detlef Steuer <detlef.steuer@gmx.de>
  -  CHANGES IN R 3.6.2:
    NEW FEATURES:
    * runmed(x, *) gains a new option na.action determining _how_ to
      handle NaN or NA in x.
    * dotchart() gains new options ann, xaxt, frame.plot and log.
    INSTALLATION on a UNIX-ALIKE:
    * Detection of the C stack direction has been moved from run-time
      to configure: this is safer with LTO builds and allows the
      detection to be overridden - see file config.site.
    * Source-code changes enable installation on platforms using gcc
    - fno-common (the expected default for gcc 10.x).
    C-LEVEL FACILITIES:
    * installTrChar (which is nowadays is wrapped by installChar) is
      defined in Rinternals.h.  (Neither are part of the API.)
    PACKAGE INSTALLATION:
    * Header Rconfig.h contains the value of FC_LEN_T deduced at
      installation which is used by the prototypes in headers
      R_ext/BLAS.h and R_ext/Lapack.h but to avoid extensive breakage
      this is only exposed when USE_FC_LEN_T is defined.
      If a package's C/C++ calls to BLAS/LAPACK allow for the 'hidden'
      arguments used by most Fortran compilers to pass the lengths of
      Fortran character arguments, define USE_FC_LEN_T and include
      Rconfig.h (possibly _via_ R.h) before including R_ext/BLAS.h or
      R_ext/Lapack.h.
    * A package with Fortran source code and perhaps C (but not C++)
      sources can request for its shared object/DLL to be linked by the
      Fortran compiler by including a line USE_FC_TO_LINK= in
      src/Makevars[.win] and using $(SHLIB_OPENMP_FFLAGS) as part of
      PKG_LIBS.
      The known reason for doing so is a package which uses Fortran
      (only) OpenMP on a platform where the Fortran OpenMP runtime is
      incompatible with the C one (e.g. gfortran 9.x with clang).
    UTILITIES:
    * R CMD check has a new option to mitigate checks leaving
      files/directories in /tmp.  See the 'R Internals' manual - this
      is part of --as-cran.
    Windows:
    * The default standard for C++ in package installation is C++11 (as
      it has been on other platforms where available since R 3.6.0: the
      default toolchain on Windows was defaulting to C++98).
    DEPRECATED AND DEFUNCT:
    * Support for specifying C++98 in package installation is
      deprecated.
    * Support in R CMD config for F77, FCPIFCPLAGS, CPP, CXXCPP and
      CXX98 and similar is deprecated.  (CPP is found from the system
      make and may well not be set.)
      Use $CC -E and $CXX -E instead of CPP and CXXCPP.
    BUG FIXES:
    * runmed(x, *) when x contains missing values now works
      consistently for both algorithm="Stuetzle" and "Turlach", and no
      longer segfaults for "Turlach", as reported by Hilmar Berger.
    * apply(diag(3), 2:3, mean) now gives a helpful error message.
    * dgamma(x, shape, log=TRUE) now longer overflows to Inf for shape
      < 1 and very small x, fixing PR#17577, reported by Jonathan
      Rougier.
    * Buffer overflow in building error messages fixed. Reported by
      Benjamin Tremblay.
    * options(str = .) is correctly initialized at package utils load
      time, now.  A consequence is that str() in scripts now is more
      consistent to interactive use, e.g., when displaying function(**)
      argument lists.
    * as.numeric(<call>) now gives correct error message.
    * Printing ls.str() no longer wrongly shows "<missing>" in rare
      cases.
    * Auto-printing S4 objects no longer duplicates the object, for
      faster speed and reduced memory consumption. Reported by Aaron
      Lun.
    * pchisq(<LRG>, <LRG>, ncp=100) no longer takes practically forever
      in some cases.  Hence ditto for corresponding qchisq() calls.
    * x %% L for finite x no longer returns NaN when L is infinite, nor
      suffers from cancellation for large finite L, thanks to Long Qu's
      PR#17611.
      Analogously, x %/% L and L %/% x suffer less from cancellation
      and return values corresponding to limits for large L.
    * grepl(NA, *) now returns logical as documented.
    * options(warn=1e11) is an error now, instead of later leading to C
      stack overflow because of infinite recursion.
    * R_tryCatch no longer transfers control for all conditions.
      Reported and patch provided by Lionel Henry in PR#17617.
    * format(object.size(.), digits=NULL) now works, fixing PR#17628
      reported by Jonathan Carroll.
    * get_all_vars(f, d) now also works for cases, e.g. where d
      contains a matrix.  Reported by Simon Wood in 2009 and patch
      provided by Ben Bolker in PR#13624.
      Additionally, it now also works when some variables are data
      frames, fixing PR#14905, reported by Patrick Breheny.
    * barplot() could get spacings wrong if there were exactly two bars
      PR#15522.  Patch by Michael Chirico.
    * power.t.test() works in more cases when returning values of n
      smaller than 2.
    * dotchart(*, pch=., groups=.) now works better.  Reported by
      Robert and confirmed by Nic Rochette in PR#16953.
    * canCoerce(obj, cl) no longer assumes length(class(obj)) == 1.
    * plot.formula(*, subset = *) now also works in a boundary case
      reported by Robert Schlicht (TU Dresden).
    * readBin() and writeBin() of a rawConnection() now also work in
      large cases, thanks to a report and proposal by Taeke Harkema in
      PR#17665.

  - CHANGES IN R 3.6.1:
    INSTALLATION on a UNIX-ALIKE:
    * The default detection of the shell variable libNN is overridden
      for derivatives of Debian Linux, some of which have started to
      have a /usr/lib64 directory.  (E.g. Ubuntu 19.04.)  As before, it
      can be specified in config.site.
    UTILITIES:
    * R CMD config knows the values of AR and RANLIB, often set for LTO
      builds.
    DEPRECATED AND DEFUNCT:
    * The use of a character vector with .Fortran() is formally
      deprecated and gives a non-portability warning.  (It has long
      been strongly discouraged in 'Writing R Extensions'.)
    BUG FIXES:
    * On Windows, GUI package installation via menuInstallPkgs() works
      again, thanks to Len Weil's and Duncan Murdoch's PR#17556.
    * R CMD check on data() fixing PR#17558 thanks to Duncan Murdoch.
    * quasi(*, variance = list(..)) now works more efficiently, and
      should work in all cases fixing PR#17560.  Further, quasi(var =
      mu(1-mu)) and quasi(var = "mu ^ 3") now work, and quasi(variance
      = "log(mu)") now gives a correct error message.
    * Creation of lazy loading database during package installation is
      again robust to Rprofile changing the current working directory
      (PR#17559).
    * boxplot(y ~ f, horizontal=TRUE) now produces correct x- and
      y-labels.
    * rbind.data.frame() allows to keep <NA> levels from factor columns
      (PR#17562) via new option factor.exclude.
      Additionally, it works in one more case with matrix-columns which
      had been reported on 2017-01-16 by Krzysztof Banas.
    * Correct messaging in C++ pragma checks in tools code for R CMD
      check, fixing PR#17566 thanks to Xavier Robin.
    * print()ing and auto-printing no longer differs for functions with
      a user defined print.function, thanks to Bill Dunlap's report.
    * On Windows, writeClipboard(.., format = <n>) now does correctly
      pass format to the underlying C code, thanks to a bug report
      (with patch) by Jenny Bryan.
    * as.data.frame() treats 1D arrays the same as vectors, PR#17570.
    * Improvements in smoothEnds(x, *) working with NAs (towards
      runmed() working in that case, in the next version of R).
    * vcov(glm(<quasi>), dispersion = *) works correctly again, fixing
      PR#17571 thanks to Pavel Krivitsky.
    * R CMD INSTALL of binary packages on Windows now works also with
      per-directory locking.
    * R CMD INSTALL and install.packages() on Windows are now more
      robust against a locked file in an earlier installation of the
      package to be installed.  The default value of option
      install.lock on Windows has been changed to TRUE.
    * On Unix alikes (when readline is active), only expand tilde (~)
      file names starting with a tilde, instead of almost all tildes.
    * In R documentation (*.Rd) files, \item [..] is no longer treated
      specially when rendered in LaTeX and hence pdf, but rather shows
      the brackets in all cases.
* Fri Apr 26 2019 Detlef Steuer <detlef.steuer@gmx.de>
  -  CHANGES IN R 3.6.0:
    SIGNIFICANT USER-VISIBLE CHANGES:
    * Serialization format version 3 becomes the default for
      serialization and saving of the workspace (save(), serialize(),
      saveRDS(), compiler::cmpfile()).  Serialized data in format 3
      cannot be read by versions of R prior to version 3.5.0.
      Serialization format version 2 is still supported and can be
      selected by version = 2 in the save/serialization functions.  The
      default can be changed back for the whole R session by setting
      environment variables R_DEFAULT_SAVE_VERSION and
      R_DEFAULT_SERIALIZE_VERSION to 2.  For maximal
      back-compatibility, files vignette.rds and partial.rdb generated
      by R CMD build are in serialization format version 2, and resave
      by default produces files in serialization format version 2
      (unless the original is already in format version 3).
    * The default method for generating from a discrete uniform
      distribution (used in sample(), for instance) has been changed.
      This addresses the fact, pointed out by Ottoboni and Stark, that
      the previous method made sample() noticeably non-uniform on large
      populations.  See PR#17494 for a discussion.  The previous method
      can be requested using RNGkind() or RNGversion() if necessary for
      reproduction of old results.  Thanks to Duncan Murdoch for
      contributing the patch and Gabe Becker for further assistance.
      The output of RNGkind() has been changed to also return the
      'kind' used by sample().
    NEW FEATURES:
    * Sys.setFileTime() has been vectorized so arguments path and time
      of length greater than one are now supported.
    * axis() gets new option gap.axis = NA for specifying a
      multiplication factor for the minimal "gap" (distance) between
      axis labels drawn.  Its default is 1 for labels _parallel_ to the
      axis, and 0.25 for perpendicular ones.
      Perpendicular labels no longer overlap, fixing bug PR#17384.
    * The default method of plot() gains new arguments xgap.axis = NA
      and ygap.axis = NA to be passed to the x- and y- axis(..,
      gap.axis=*) calls.
    * removeSource() now works not only for functions but also for some
      language objects.
    * as.call(), rep.int(), rep_len() and nchar() dispatch internally.
    * is(object, class2) looks for class2 in the calling namespace
      after looking in the namespace of class(object).
    * extendrange(.., f) with a length-2 f now extends separately to
      the left and the right.
    * lengths() dispatches internally to S4 methods.
    * download.file() on Windows now uses URLdecode() to determine the
      file extension, and uses binary transfer (mode = "wb") also for
      file extension .rds.
      The help page for download.file() now contains the same
      information on all platforms.
    * Setting C locale for collation _via_ environment variables LC_ALL
      and LC_COLLATE and _via_ a call to Sys.setlocale() now takes
      precedence over environment variable R_ICU_LOCALE.
    * There is a new function, nullfile(), to give the file name of the
      null system device (e.g., /dev/null) on the current platform.
    * There are two new options, keep.parse.data and
      keep.parse.data.pkgs, which control whether parse data are
      included into sources when keep.source or keep.source.pkgs is
      TRUE.  By default, keep.parse.data.pkgs is now FALSE, which
      changes previous behavior and significantly reduces space and
      time overhead when sources are kept when installing packages.
    * In rapply(x, ..), x can also be "list-like" and of length >=
      2^{31}.
    * trimws() gets new optional whitespace argument, allowing more
      extensive definitions of "space", such as including Unicode
      spaces (as wished in PR#17431).
    * weighted.mean() no longer coerces the weights to a double/numeric
      vector, since sum() now handles integer overflow. This makes
      weighted.mean() more polymorphic and endomorphic, but be aware
      that the results are no longer guaranteed to be a vector of type
      double.
    * When loading namespaces, S3 method registrations which overwrite
      previous registrations are now noted by default (using
      packageStartupMessage()).
    * compiler::cmpfile() gains a version argument, for use when the
      output file should be saved in serialization format 2.
    * The axis labeling in the default method of pairs() may now be
      toggled by new options horOdd and verOdd.
    * (Not Windows nor macOS.) Package tcltk now supports an
      environment variable R_DONT_USE_TK which if set disables Tk
      initialization.  This is intended for use to circumvent errors in
      loading the package, e.g. with recent Linux running under an
      address sanitizer.
    * The numeric method of all.equal() gets optional arguments countEQ
      and formatFUN.  If countEQ is true, the mean error is more
      sensible when many entries are *eq*ual.
    * outer(x,y, FUN = "*") is more efficient using tcrossprod(u,v)
      instead of u %*% t(v).
    * vcov(<mlm>) is more efficient via new optional arguments in
      summary.mlm().
    * The default method of summary() gets an option to choose the
      _kind_ of quantile()s to use; wish of PR#17438.
    * Fitting multiple linear models _via_ lm() does work with _matrix_
      offsets, as suggested in PR#17407.
    * The new functions mem.maxVSize() and mem.maxMSize() allow the
      maximal size of the vector heap and the maximal number of nodes
      allowed in the current R process to be queried and set.
    * news() gains support for NEWS.md files.
    * An effort has been started to have our reference manuals, i.e.,
      all help pages. show platform-independent information (rather
      than Windows or Unix-alike specifics visible only on that
      platform).  Consequently, the Windows version of X11() / x11()
      got identical formal arguments to the Unix one.
    * sessionInfo()$running has been factored out in a new variable
      osVersion.
    * slice.index() now also works for multi-dimensional margins.
    * untar() used with an external tar command assumes this supports
      decompression including xz and automagically detecting the
      compression type.  This has been true of all mainstream
      implementations since 2009 (for GNU tar, since version 1.22):
      older implementations are still supported _via_ the new argument
      support_old_tars whose default is controlled by environment
      variable R_SUPPORT_OLD_TARS.  (It looks like NetBSD and OpenBSD
      have 'older' tar commands for this purpose.)
    * The new function asplit() allow splitting an array or matrix by
      its margins.
    * New functions errorCondition() and warningCondition() provide a
      convenient way to create structured error and warning objects.
      .Deprecated() now signals a warning of class "deprecatedWarning",
      and .Defunct() now signals an error of class "defunctError".
    * Many 'package not found' errors are now signaled as errors of
      class "packageNotFoundError".
    * As an experimental feature, when loadNamespace() fails because
      the requested package is not available the error is initially
      signaled with a retry_loadNamespace restart available.  This
      allows a calling handler to try to install the package and
      continue.
    * S3method() directives in NAMESPACE can now also be used to
      perform _delayed_ S3 method registration.
    * Experimentally, setting environment variable
      _R_CHECK_LENGTH_1_LOGIC2_ will lead to warnings (or errors if the
      variable is set to a 'true' value) when && or || encounter and
      use arguments of length more than one.
    * Added "lines" and "chars" coordinate systems to grconvertX() and
      grconvertY().
    * getOption() is more efficient notably for the rare case when
      called with two arguments, from several contributors in PR#17394.
    * In .col(dim) and .row(dim), dim now may also be an integer-valued
      "double".
    * sQuote() and dQuote() get an explicit q argument with obvious
      default instead of using getOption("fancyQuotes") implicitly and
      unconditionally.
    * unzip() can list archives with comments and with spaces in file
      names even using an external unzip command.
    * Command line completion has a new setting rc.settings(dots =
      FALSE) to remove ... from the list of possible function
      arguments.
    * library() no longer checks packages with compiled code match
      R.version$platform.  loadNamespace() never has, and increasingly
      the 'canonical name' does not reflect the important
      characteristics of compiled code.
    * The primitive functions drop() and unclass() now avoid
      duplicating their data for atomic vectors that are large enough,
      by returning ALTREP wrapper objects with adjusted attributes.
      R-level assignments to change attributes will also use wrapper
      objects to avoid duplicating data for larger atomic vectors. R
      functions like structure() and unname() will therefore not
      duplicate data in these settings.  Generic vectors as produced by
      list() are not yet covered by this optimization but may be in due
      course.
    * In formals(), envir becomes an optional argument instead of being
      hardwired.
    * Instead of signalling an error for an invalid S4 object x, str(x)
      now gives a warning and subsequently still shows most parts of x,
      e.g., when slots are missing.
    * gamma(x) and lgamma(x) no longer warn when correctly returning
      Inf or underflowing to zero.  This helps maximum likelihood and
      similar computations.
    * convertColor() is now vectorized, so a lot faster for converting
      many colours at once.  The new argument vectorized to
      colorConverter() ensures that non-vectorized colour converters
      still work.  (Thanks to Brodie Gaslam.)
    * download.file() and url() get new argument headers for custom
      HTTP headers, e.g., allowing to perform basic http
      authentication, thanks to a patch contributed by G'abor Cs'ardi.
    * File-based connection functions file(), gzfile(), bzfile() and
      xzfile() now signal an error when used on a directory.
    * For approx(), splinefun() _etc_, a new setting ties =
      c("ordered", <fun>) allows skipping the sorting and still treat
      ties.
    * format(x) gives a more user friendly error message in the case
      where no method is defined.  A minimal method is provided in
      format.default(x) when isS4(x) is true.
    * which(x) now also works when x is a long vector, thanks to
      Suharto Anggono's PR#17201.  *NB*: this may return a double
      result, breaking the previous guarantee of an integer result.
    * seq.default() is more careful to return an integer (as opposed to
      double) result when its arguments are large and/or classed
      objects; see comment #9 of Suharto Anggono's PR#17497.
    * The plot() method for lm and glm fits, plot.lm(), gains a new
      option iter.smooth with a default of 0 for binomial fits, no
      longer down-weighting when smoothing the residuals.
    * zip() passes its list of files _via_ standard input to the
      external command when too long for the command line (on some
      platforms).
    * data() gains an overwrite argument.
    * t.test() now also returns the standard error (in list component
      stderr).
    * model.matrix(*, contrasts.arg = CC) now warns about invalid
      contrasts.args.
    * Performance of substr() and substring() has been improved.
    * stopifnot() has been simplified thanks to Suharto Anggono's
      proposals to become considerably faster for cheap expressions.
    * The default 'user agent' has been changed when accessing http://
      and https:// sites using libcurl.  (A site was found which caused
      libcurl to infinite-loop with the previous default.)
    * sessionInfo() now also contains RNGkind() and prints it when it
      differs from the default; based on a proposal and patch by Gabe
      Becker in PR#17535.  Also, RNGversion(getRversion()) works
      directly.
    * library() and require() now allow more control over handling
      search path conflicts when packages are attached. The policy is
      controlled by the new conflicts.policy option.
    * barplot() gets a formula method, thanks to a patch proposal by
      Arni Magnusson in PR#17521.
    * pmax() and pmin(x) now also work for long vectors, thanks to
      Suharto Anggono's PR#17533.
    * bxp() now warns when omitting duplicated arguments.
    * New hcl.colors() function to provide wide range of HCL-based
      colour palettes with much better perceptual properties than the
      existing RGB/HSV-based palettes like rainbow().
      Also a new hcl.pals() function to list available palette names
      for hcl.colors().
      Contributed by Achim Zeileis.
    * The default colours for image() and filled.contour() are now
      based on hcl.colors().
    * The palette-generating functions rainbow(), gray.colors(), etc.
      get a new rev argument to facilitate reversing the order of
      colors.
    * New str2lang() and str2expression() as streamlined versions of
      parse(text=., keep.source=FALSE) allow to abstract typical call
      constructions, e.g., in formula manipulations.  (Somewhat
      experimental)
    * Add update_PACKAGES() for incrementally updating a package
      repository index, instead of rebuilding the index from scratch.
      Thanks to Gabe Becker in PR#17544 for the patch, based on part of
      his switchr package.
    INSTALLATION on a UNIX-ALIKE:
    * The options selected for the C++ compiler default to the C++11
      standard if supported, otherwise to the C++98 standard.
    * Visibility macros such as C_VISIBILITY can now be user-set
      (including to empty), e.g. in config.site.
    * Macro FCLIBS, which has sometimes been needed on Solaris, has
      been renamed to FCLIBS_XTRA.
    * Macro F77 is always set to the value of FC, so the latter should
      be set to user-select the Fortran compiler for both fixed-form
      and free-form Fortran.  In particular, gfortran is now the first
      choice for F77, not f95.
      Macros FFLAGS and FCFLAGS remain distinct to allow for a compiler
      which needs a flag to select free- or fixed-form Fortran (most
      use the source-file extension to choose: .f is fixed-form and
      .f90 and .f95 are free-form).
      If only one of them is set, its value is used for both.
    * The special-casing of CFLAGS, CXXFLAGS and FFLAGS for Intel
      compilers on Linux has been removed: we do not have recent
      experience but the generic defaults now chosen are the same as
      those previously special-cased for x86_64.
      If necessary, override the defaults on the configure command line
      or in file config.site.
    * Long-untested configure support for HP-UX and very old versions
      of Linux has been removed.
    * configure --with-blas (without specifying a value) includes
      OpenBLAS in its search (before ATLAS and a generic BLAS).  This
      follows recent versions of the ax_blas autoconf macro.
    * The configure macro MAKEINFO has been updated to TEXI2ANY.
    * Support for make install-strip has been enhanced.
    PACKAGE INSTALLATION:
    * Source package installation is by default 'staged': the package
      is installed into a temporary location under the final library
      directory and moved into place once the installation is complete.
      The benefit is that partially-installed packages are hidden from
      other R sessions.
      The overall default is set by environment variable
      R_INSTALL_STAGED.  R CMD INSTALL has new options --staged-install
      and --no-staged-install, and packages can use the StagedInstall
      field in their DESCRIPTION file to opt out.  (That opt-out is a
      temporary measure which may be withdrawn in future.)
      Staged installation requires either --pkglock or --lock, one of
      which is used by default.
    * The interpretation of source code with extension .f is changing.
      Previously this denoted FORTRAN 77 code, but current compilers no
      longer have a FORTRAN 77 mode and interpret it as 'fixed-form'
      Fortran 90 (or later where supported) code.  Extensions .f90 and
      .f95 continue to indicate 'free-form' Fortran code.
      Legal FORTRAN 77 code is also legal fixed-form Fortran 9x;
      however this change legitimizes the use of later features, in
      particular to replace features marked 'obsolescent' in Fortran 90
      and 'deleted' in Fortran 2018 which gfortran 8.x and later warn
      about.
    * Packages containing files in the src directory with extensions
      .f90 or .f95 are now linked using the C or C++ compiler rather
      than the Fortran 9x compiler.  This is consistent with fixed-form
      Fortran code and allows mixing of C++ and free-form Fortran on
      most platforms.
      Consequentially, a package which includes free-form Fortran 9x
      code which uses OpenMP should include SHLIB_OPENMP_CFLAGS (or the
      CXXFLAGS version if they also include C++ code) in PKG_LIBS
      rather than SHLIB_OPENMP_FCFLAGS - fortunately on almost all
      current platforms they are the same flag.
    * Macro PKG_FFLAGS will be used for the compilation of both
      fixed-form and free-form Fortran code unless PKG_FCFLAGS is also
      set (in src/Makevars or src/Makevars.win).
    * The make macro F_VISIBILITY is now preferred for both fixed-form
      and free-form Fortran, for use in src/Makevars and similar.
    * R CMD INSTALL gains a new option --strip which (where supported)
      strips installed shared object(s): this can also be achieved by
      setting the environment variable _R_SHLIB_STRIP_ to a true value.
      The new option --strip-lib attempts stripping of static and
      shared libraries installed under lib.
      These are most useful on platforms using GNU binutils (such as
      Linux) and compiling with -g flags.
    * There is more support for installing UTF-8-encoded packages in a
      strict Latin-1 locale (and probably for other Latin locales):
      non-ASCII comments in R code (and NAMESPACE files) are worked
      around better.
    UTILITIES:
    * R CMD check now optionally checks makefiles for correct and
      portable use of the SHLIB_OPENMP_*FLAGS macros.
    * R CMD check now evaluates \Sexpr{} expressions (including those
      in macros) before checking the contents of Rd files and so
      detects issues both in evaluating the expressions and in the
      expanded contents.
    * R CMD check now lists missing packages separated by commas and
      with regular quotes such as to be useful as argument in calling
      install.packages(c(..)); from a suggestion by Marcel Ramos.
    * tools::Rd2latex() now uses UTF-8 as its default output encoding.
    * R CMD check now checks line endings of files with extension .hpp
      and those under inst/include.  The check now includes that a
      non-empty file is terminated with a newline.
      R CMD build will correct line endings in such files.
    * R CMD check now tries re-building all vignettes rather than
      stopping at the first error: whilst doing so it adds 'bookmarks'
      to the log.  By default (see the 'R Internals' manual) it
      re-builds each vignette in a separate process.
      It now checks for duplicated vignette titles (also known as
      'index entries'): they are used as hyperlinks on CRAN package
      pages and so do need to be unique.
    * R CMD check has more comprehensive checks on the data directory
      and the functioning of data() in a package.
    * R CMD check now checks autoconf-generated configure files have
      their corresponding source files, including optionally attempting
      to regenerate them on platforms with autoreconf.
    * R CMD build has a new option --compression to select the
      compression used for the tarball.
    * R CMD build now removes src/*.mod files on all platforms.
    C-LEVEL FACILITIES:
    * New pointer protection C functions R_PreserveInMSet and
      R_ReleaseFromMSet have been introduced to replace UNPROTECT_PTR,
      which is not safe to mix with UNPROTECT (and with
      PROTECT_WITH_INDEX). Intended for use in parsers only.
    * NAMEDMAX has been raised to 7 to allow further protection of
      intermediate results from (usually ill-advised) assignments in
      arguments to BUILTIN functions. Properly written package code
      should not be affected.
    * R_unif_index is now considered to be part of the C API.
    * R_GetCurrentEnv() allows C code to retrieve the current
      environment.
    DEPRECATED AND DEFUNCT:
    * Argument compressed of untar() is deprecated - it is only used
      for external tar commands which increasingly for extraction
      auto-detect compression and ignore their zjJ flags.
    * var(f) and hence sd(f) now give an error for factor arguments;
      they gave a deprecation warning since R 3.2.3, PR#16564.
    * Package tools' vignetteDepends() has been deprecated (it called a
      function deprecated since Feb 2016), being partly replaced by
      newly exported vignetteInfo().
    * The f77_f2c script has been removed: it no longer sufficed to
      compile the .f files in R.
    * The deprecated legacy support of make macros such as CXX1X has
      been removed: use the CXX11 forms instead.
    * Make macro F77_VISIBILITY is deprecated in favour of
      F_VISIBILITY.
    * Make macros F77, FCPIFCPLAGS and SHLIB_OPENMP_FCFLAGS are
      deprecated in favour of FC, FPICFLAGS and SHLIB_OPENMP_FFLAGS
      respectively.
    * $.data.frame had become an expensive version of the default
      method, so has been removed. (Thanks to Radford Neal for picking
      this up and to Duncan Murdoch for providing a patch.)
    BUG FIXES:
    * replayPlot(r) now also works in the same R session when r has
      been "reproduced" from serialization, typically after saving to
      and reading from an RDS file.
    * substr() and substring() now signal an error when the input is
      invalid UTF-8.
    * file.copy() now works also when its argument to is of length
      greater than one.
    * mantelhaen.test() no longer suffers from integer overflow in
      largish cases, thanks to Ben Bolker's PR#17383.
    * Calling setGeneric("foo") in a package no longer fails when the
      enclosing environment of the implicit generic foo() is
      .GlobalEnv.
    * untar(file("<some>.tar.gz"), *) now gives a better error message,
      suggesting to use gzfile() instead.
    * Method dispatch uses more relevant environments when looking up
      class definitions.
    * The documentation for identify() incorrectly claimed that the
      indices of identified points were returned in the order that the
      points were selected.  identify() now has a new argument order to
      allow the return value to include the order in which points were
      identified; the documentation has been updated.  Reported by
      Richard Rowe and Samuel Granjeaud.
    * order(...., decreasing=c(TRUE, FALSE)) could fail in some cases.
      Reported from StackOverflow via Karl Nordstr"om.
    * User macros in Rd files now accept empty and multi-line
      arguments.
    * Changes in print.*(), thanks to Lionel Henry's patches in
      PR#17398:
    * Printing lists, pairlists or attributes containing calls with
      S3 class no longer evaluate those.
    * Printing S4 objects within lists and pairlists dispatches
      with show() rather than print(), as with auto-printing.
    * The indexing tags (names or [[<n>]]) of recursive data
      structures are now printed correctly in complex cases.
    * Arguments supplied to print() are now properly forwarded to
      methods when printing lists, pairlists or attributes
      containing S3 objects.
    * The print parameters are now preserved when printing S3
      objects or deparsing symbols and calls.  Previously, printing
      lists containing S3 objects or expressions would reset these
      parameters.
    * Printing lists, pairlists or attributes containing functions
      now uses srcref attributes if present.
    * Calling install.packages() with a length zero pkgs argument now
      is a no-op (PR#17422).
    * unlist(x) now returns a correct factor when x is a nested list
      with factor leaves, fixing PR#12572 and PR#17419.
    * The documentation help(family) gives more details about the aic
      component, thanks to Ben Bolker's prompting.
    * The documentation for attributes and `attributes<-` now gives x
      as name of the first and main argument which the implementation
      has been requiring, fixing PR#17434.  For consistency, the first
      argument name is also changed from obj to x for
      `mostattributes<-`.
    * strwidth() now uses par("font") as default font face (PR#17352).
    * plot(<table>, log="x") no longer warns about log.
    * The print() method for "htest" objects now formats the test
      statistic and parameter directly and hence no longer rounds to
      units _before_ the decimal point.  Consequently, printing of
      t.test() results with a small number of digits now shows
      non-large df's to the full precision (PR#17444).
    * kruskal.test() and fligner.test() no longer erroneously insist on
      numeric g group arguments (PR#16719).
    * Printing a news db via the browser now does a much better job
      (PR#17433).
    * print.aov() missed column names in the multivariate case due to
      misspelling (reported by Chris Andrews).
    * axis() now creates valid at locations also for small subnormal
      number ranges in log scale plots.
    * format.POSIXlt() now also recycles the zone and gmtoff list
      components to full length when needed, and its internal C code
      detects have_zone in more cases.  In some cases, this changes its
      output to become compatible with format.POSIXct().
    * On Windows, detectCores() in package parallel now detects
      processors in all processor groups, not just the group R is
      running in (impacts particularly systems with more than 64
      logical processors).  Reported by Arunkumar Srinivasan.
    * On Windows, socketSelect() would hang with more than 64 sockets,
      and hence parallel::clusterApplyLB() would hang with more than 64
      workers.  Reported by Arunkumar Srinivasan.
    * as(1L, "double") now does coerce (PR#17457).
    * lm.influence(), influence.measures(), rstudent() etc now work
      (more) correctly for multivariate models ("mlm"), thanks to
      (anonymous) stackoverflow remarks.
    * sample.int(2.9, *, replace=TRUE) again behaves as documented and
      as in R < 3.0.0, namely identically to sample.int(2, ..).
    * Fixes to convertColor() for chromatic adaptation; thanks to
      Brodie Gaslam PR#17473.
    * Using \Sexpr[stage=install]{..} to create an Rd section no longer
      gives a warning in R CMD check; problem originally posted by
      G'abor Cs'ardi, then reported as PR#17479 with a partial patch by
      Duncan Murdoch.
    * Parse data now include a special node for equal assignment.
    * split.default() no longer relies on [[<-(), so it behaves as
      expected when splitting an object by a factor with the empty
      string as one of its levels.  Thanks to Brad Friedman for the
      report.
    * Line numbers in messages about .Rd files are now more reliable,
      thanks to a patch from Duncan Murdoch.
    * In the numeric method for all.equal(), a numeric scale argument
      is now checked to be positive and allowed to be of length > 1.
      (The latter worked originally and with a warning in recent
      years).
    * Deferred string conversions now record the OutDec option setting
      when not equal to the default.  Reported by Michael Sannella.
    * When y is numeric and f a factor, plot(y ~ f) nicely uses "y" and
      "f" as y- and x-labels.  The more direct boxplot(y ~ f) now does
      too.  The new argument ann = FALSE may be used to suppress these.
    * Subassignment to no/empty rows of a data frame is more consistent
      and typically a no-op in all cases instead of sometimes an error;
      part of Emil Bode's PR#17483.
    * Calls like formatC(*, zero.print = "< 0.001") no longer give an
      error and are further improved via new optional argument
      replace.zero.  Reported by David Hugh-Jones.
    * methods::formalArgs("<fn>") now finds the same function as
      formals("<fn>"), fixing Emil Bode's PR#17499.
    * The methods package better handles duplicated class names across
      packages.
    * The default method of seq() now avoids integer overflow, thanks
      to the report and "cumsum" patch of Suharto Anggono's PR#17497.
    * sub() no longer loses encodings for non-ASCII replacements
      (PR#17509).
    * Fix for rotated raster image on X11 device.  (Partial fix for
      PR#17148; thanks to Mikko Korpela).
    * formula(model.frame(frml, ..)) now returns frml in all cases,
      thanks to Bill Dunlap.  The previous behavior is available as
      DF2formula(<model.frame>).
    * ar.ols() also returns scalar var.pred in univariate case
      (PR#17517).
    * normalizePath() now treats NA path as non-existent and normalizes
      it to NA.  file.access() treats NA file name as non-existent.
      file.edit() and connection functions such as file() now treat NA
      file names as errors.
    * The internal regularize.values() auxiliary of approx(),
      splinefun() etc now warns again when there are ties and the
      caller did not specify ties.  Further, it no longer duplicates x
      and y unnecessarily when x is already sorted (PR#17515).
    * strtoi("", base) now gives NA on all platforms, following its
      documentation.  Reported by Michael Chirico.
    * In the definition of an S4 class, prototype elements are checked
      against the slots of the class, with giving a prototype for an
      undefined slot now being an error.  (Reported by Bill Dunlap.)
    * From setClassUnion(), if environment variable
      _R_METHODS_SHOW_CHECKSUBCLASSES is set to true, the internal
      .checkSubclasses() utility prints debugging info to see where it
      is used.
    * max.col(m) with an m of zero columns now returns integer NA
      (instead of 1).
    * axTicks() no longer returns small "almost zero" numbers (in
      exponential format) instead of zero, fixing Ilario Gelmetti's
      PR#17534.
    * isSymmetric(matrix(0, dimnames=list("A","b"))) is FALSE again, as
      always documented.
    * The cairo_pdf graphics device (and other Cairo-based devices) now
      clip correctly to the right and bottom border.
      There was an off-by-one-pixel bug, reported by Lee Kelvin.
    * as.roman(3) <= 2:4 and all other comparisons now work, as do
      group "Summary" function calls such as max(as.roman(sample(20)))
      and as.roman(NA).  (Partly reported by Bill Dunlap in PR#17542.)
    * reformulate("x", response = "sin(y)") no longer produces extra
      back quotes, PR#17359, and gains new optional argument env.
    * When reading console input from stdin with re-encoding (R
    - -encoding=enc < input) the code on a Unix-alike now ensures that
      each converted input line is terminated with a newline even if
      re-encoding fails.
    * as.matrix.data.frame() now produces better strings from logicals,
      thanks to PR#17548 from Gabe Becker.
    * The S4 generic signature of rowSums(), rowMeans(), colSums() and
      colMeans() is restricted to "x".
    * match(x, tab) now works for long _character_ vectors x, thanks to
      PR#17552 by Andreas Kersting.
    * Class unions are unloaded when their namespace is unloaded
      (PR#17531, adapted from a patch by Brodie Gaslam).
    * selectMethod() is robust to ANY-truncation of method signatures
      (thanks to Herve Pages for the report).
* Mon Mar 11 2019 Detlef Steuer <detlef.steuer@gmx.de>
  -  CHANGES IN R 3.5.3:
    INSTALLATION on a UNIX-ALIKE:
    * Detection of flags for C++98/11/14/17 has been improved: in
      particular if CXX??STD is set, it is tried first with no
      additional flags.
    PACKAGE INSTALLATION:
    * New macro F_VISIBILITY as an alternative to F77_VISIBILITY.  This
      will become the preferred form in R 3.6.0.
    BUG FIXES:
    * writeLines(readLines(fnam), fnam) now works as expected, thanks
      to Peter Meissner's PR#17528.
    * setClassUnion() no longer warns, but uses message() for now, when
      encountering "non local" subclasses of class members.
    * stopifnot(exprs = T) no longer fails.
* Tue Jan 15 2019 Todd R <toddrme2178@gmail.com>
  - Add architecture-independent package directory.
    Taken from the Fedora version of R.
  - Add RPM macros to ease installation of R packages.
  - Fix building on older versions of openSUSE.
