Can be used to speed up reshaping in line-breaking situations. Essentially, after shaping, it returns positions in the input string (some of the cluster boundaries) that are "safe to break" in that if the text is segmented at that position and two sides reshaped and concatenated, the shaping result is exactly the same as shaping the text in one piece. + hb-view and hb-shape and hb-shape now take --verify, which verifies the above property. + Some corner cases of the implementation are still not quite working. Those will be fixed in subsequent releases. * Sun Sep 03 2017 email@example.com - Update to version 1.4.8: + Major fix to avar table handling. + Rename hb-shape --show-message to --trace. + Build fixes. - Changes from version 1.4.7: + Multiple Indic, Tibetan, and Cham fixes. + CoreText: Allow disabling kerning. + Adjust Arabic feature order again. + Misc build fixes. * Tue Apr 25 2017 firstname.lastname@example.org - Update to version 1.4.6: + Graphite2: Fix RTL positioning issue. + Backlist GDEF of more versions of Padauk and Tahoma. + New, experimental, cmake alternative build system. * Sat Mar 11 2017 email@example.com - Update to version 1.4.5 (fate#322101): + Revert "Fix Context lookup application when moving back after a glyph..."

Reduces dependence on version of Unicode data in glib. - Changes from version 1.4.0: + Merged "OpenType GX" branch which adds core of support for OpenType 1.8 Font Variations. + New API: - hb_font_set_var_coords_normalized(). - HB_OT_LAYOUT_NO_VARIATIONS_INDEX. - hb_ot_layout_table_find_feature_variations(). - hb_ot_layout_feature_with_variations_get_lookups(). - hb_shape_plan_create2(). - hb_shape_plan_create_cached2(). + Currently variations in GSUB/GPOS/GDEF are fully supported, and no other tables are supported. In particular, fvar/avar are NOT supported, hence the hb_font_set_var_coords_normalized() taking normalized coordinates. API to take design coordinates will be added in the future. + HVAR/VVAR/MVAR support will also be added to hb-ot-font in the future. + Fix regression in GDEF glyph class processing. + Add decompositions for Chakma, Limbu, and Balinese in USE shaper. + Misc fixes. * Tue Dec 06 2016 firstname.lastname@example.org - Update to version 1.3.4: + Fix vertical glyph origin in hb-ot-font. + Implement CBDT/CBLC color font glyph extents in hb-ot-font. * Fri Nov 04 2016 email@example.com - Update to version 1.3.3: + Implement parsing of OpenType MATH table. * Wed Oct 26 2016 firstname.lastname@example.org - Drop pkgconfig(icu-le) BuildRequires: That was actually removed upstream in version 0.9.21. * Sun Oct 02 2016 email@example.com - Update to version 1.3.2: + Fix build of hb-coretext on older OS X versions. * Thu Sep 15 2016 firstname.lastname@example.org - Update to version 1.3.1: + Blacklist bad GDEF of more fonts. + More CoreText backend crash fixes with OS X 10.9.5. + Misc fixes. * Thu Jul 28 2016 email@example.com - Update to version 1.3.0: + Update to Unicode 9.0.0. + Move Javanese from Indic shaper to Universal Shaping Engine. + Allow MultipleSubst to delete a glyph (matching Windows engine). + Update Universal Shaping Engine to latest draft from Microsoft. + DirectWrite backend improvements. Note: this backend is for testing ONLY. + CoreText backend improvements with unreachable fonts. + Implement symbol fonts (cmap 3.0.0) in hb-ft and hb-ot-font. + Blacklist bad GDEF of more fonts (Tahoma & others). + Misc fixes. * Fri May 27 2016 firstname.lastname@example.org - Update to GNOME 3.20.2 FATE#318572 * Tue May 10 2016 email@example.com - Update to version 1.2.7: + Blacklist another version of Times New Roman (Bold) Italic from Windows 7. + Fix Mongolian Free Variation Selectors shaping with certain fonts. + Fix Tibetan shorthand contractions shaping. + Improved list of language tag mappings. + Unbreak build on Windows CE. + Make 'glyf' table loading lazy in hb-ot-font. * Mon Apr 11 2016 firstname.lastname@example.org - Update to version 1.2.6: + Blacklist GDEF table of another set of Times New Roman (Bold) Italic. + DirectWrite backend improvements. Note: DirectWrite backend is exclusively for our internal testing and should NOT be used in any production system whatsoever. * Fri Apr 08 2016 email@example.com - Update to version 1.2.5: + Fix GDEF mark-filtering-set, which was broken in 1.2.3. * Fri Mar 18 2016 firstname.lastname@example.org - Update to version 1.2.4: + Synthesize GDEF glyph class for any glyph that does not have one in GDEF. Hope we don't discover broken fonts that shape badly with this change. + Misc build and other minor fixes. + API changes: Added HB_NDEBUG. It's fine for production systems to define this to disable high-overhead debugging checks. * Tue Mar 01 2016 email@example.com - Update to version 1.2.3: + Blacklist GDEF table of certain versions of Times New Roman (Bold) Italic, due to bug in glyph class of ASCII double-quote character. This should address "regression" introduced in 1.2.0 when we switched mark zeroing in most shapers from BY_UNICODE_LATE to BY_GDEF_LATE. This fourth release in a week should finally stablize things... + hb-ot-font's get_glyph() implementation saw some optimizations. Though might be really hard to measure in real-world situations. + Also, two rather small API changes: - We now disable some time-consuming internal bookkeeping if built with NDEBUG defined. This is a first time that we use NDEBUG to disable debug code. If there exist production systems that do NOT want to enable NDEBUG, please let me know and I'll add HB_NDEBUG. - Added get_nominal_glyph() and get_variation_glyph() instead of get_glyph() + New API: - hb_font_get_nominal_glyph_func_t. - hb_font_get_variation_glyph_func_t. - hb_font_funcs_set_nominal_glyph_func(). - hb_font_funcs_set_variation_glyph_func(). - hb_font_get_nominal_glyph(). - hb_font_get_variation_glyph(). + Deprecated API: - hb_font_get_glyph_func_t. - hb_font_funcs_set_glyph_func(). + Clients that implement their own font-funcs are encouraged to replace their get_glyph() implementation with a get_nominal_glyph() and get_variation_glyph() pair. The variation version can assume that variation_selector argument is not zero. Old (deprecated) functions will continue working indefinitely using internal gymnastics; it is just more efficient to use the new functions. - Changes from version 1.2.2: + Fix regression with mark positioning with fonts that have non-zero mark advances. This was introduced in 1.2.0 while trying to make mark and cursive attachments to work together. I have partially reverted that, so this version is much more like what we had before. All clients who updated to 1.2.0 should update to this version. - Changes from version 1.2.1: + CoreText: - Fix bug with wrong scale if font scale was changed later (gh/libass/libass/#212). - Drastically speed up font initialization. - Fix tiny leak. + Group ZWJ/ZWNJ with previous syllable under cluster-level=0 (gh/behdad/harfbuzz#217). + Add test/shaping/README.md about how to add tests to the suite. * Mon Feb 22 2016 firstname.lastname@example.org - Add Conflicts: cantarell-fonts < 0.0.23. Previous versions of cantarell-fonts have a bug that harfbuzz now exposes, so add a conflicts to work-around that. * Fri Feb 19 2016 email@example.com - Update to version 1.2.0: + Fix various issues (hangs mostly) in case of memory allocation failure. + Change mark zeroing types of most shapers from BY_UNICODE_LATE to BY_GDEF_LATE. This seems to be what Uniscribe does. + Change mark zeroing of USE shaper from NONE to BY_GDEF_EARLY. That's what Windows does. + Allow GPOS cursive connection on marks, and fix the interaction with mark attachment. This work resulted in some changes to how mark attachments work (gh#behdad/harfbuzz#211). + Graphite2 shaper: improved negative advance handling (eg. Nastaliq). + Add nmake-based build system for Windows. + Minor speedup. + Misc. improvements. * Thu Jan 14 2016 firstname.lastname@example.org - Update to version 1.1.3: + Ported Indic shaper to Unicode 8.0 data. + Universal Shaping Engine fixes. + Speed up CoreText shaper when font fallback happens in CoreText. + Documentation improvements, thanks to Khaled Hosny. + Very rough directwrite shaper for testing. + Misc bug fixes. + API extensions. * Sun Nov 29 2015 email@example.com - Update to version 1.1.2: + Fix badly-broken fallback shaper that affected terminology. + Fix y_scaling in Graphite shaper. + API changes: An unset glyph_h_origin() function in font-funcs now (sensibly) implies horizontal origin at 0,0. Ie, the nil callback returns true instead of false. As such, implementations that have a glyph_h_origin() that simply returns true, can remove that function with HarfBuzz >= 1.1.2. This results in a tiny speedup. * Wed Nov 25 2015 firstname.lastname@example.org - Update to version 1.1.1: + Build fixes, specially for hb-coretext. * Fri Nov 20 2015 email@example.com - Update to version 1.1.0: + Implement 'stch' stretch feature for Syriac Abbreviation Mark. + Disable use of decompose_compatibility() callback. + Implement "shaping" of various Unicode space characters, even if the font does not support them. + If font does not support U+2011 NO-BREAK HYPHEN, fallback to U+2010 HYPHEN. + Changes resulting from libFuzzer continuous fuzzing: - Reject font tables that need more than 8 edits. - Bound buffer growth during shaping to 32x. - Fix assertions and other issues at OOM / buffer max-growth. + Misc fixes and optimizations. + API changes: All fonts created with hb_font_create() now inherit from (ie. have parent) hb_font_get_empty(). * Mon Oct 19 2015 firstname.lastname@example.org - Update to version 1.0.6: + Reduce max nesting level in OT lookups from 8 to 6. + Fix memory access issue in ot-font. + Revert default load-flags of fonts created using hb_ft_font_create() back to FT_LOAD_DEFAULT|FT_LOAD_NO_HINTING.
