- Update to version 4.0.0:
+ New public API to create subset plan and gather information on
things like glyph mappings in the final subset. The plan can
then be passed on to perform the subsetting operation.
+ Draw API for extracting glyph shapes have been extended and
finalized and is no longer an experimental API. The draw API
supports glyf, CFF and CFF2 glyph outlines tables, and applies
variation settings set on the font as well as synthetic slant.
The new public API is not backward compatible with the
previous, non-public, experimental API.
+ The hb-view tool will use HarfBuzz draw API to render the
glyphs instead of cairo-ft when compiled with Cairo 1.17.5 or
newer, setting HB_DRAW environment variable to 1 or 0 will
force using or not use the draw API, respectively.
+ The hb-shape and hb-view tools now default to using HarfBuzz’s
own font loading functions (ot) instead of FreeType ones (ft).
They also have a new option, --font-slant, to apply synthetic
slant to the font.
+ HarfBuzz now supports more than 65535 (the OpenType limit)
glyph shapes and metrics. See be-fonts/boring-expansion-spec#6
and be-fonts/boring-expansion-spec#7 for details.
+ New API to get the dominant horizontal baseline tag for a given
script.
+ New API to get the baseline positions from the font, and
synthesize missing ones. As well as new API to get font metrics
and synthesize missing ones.
+ Improvements to finding dependencies on Windows when building
with Visual Studio.
+ New buffer flag, HB_BUFFER_FLAG_PRODUCE_UNSAFE_TO_CONCAT, that
must be set during shaping for HB_GLYPH_FLAG_UNSAFE_TO_CONCAT
flag to be reliably produced. This is to limit the performance
hit of producing this flag to when it is actually needed.
+ Documentation improvements.

- Drop pkgconfig(gobject-2.0) BuildRequires: not needed/used.
* Sat Sep 09 2017 zaitor@opensuse.org
- Update to version 1.5.1:
+ Fix "unsafe-to-break" in fallback shaping and other corner
cases. All our tests pass with --verify now, meaning
unsafe-to-break API works as expected.
+ Add --unicodes to hb-view / hb-shape.
+ [indic] Treat Consonant_With_Stacker as consonant. This will
need further tweaking.
+ hb_buffer_diff() tweaks.
- Changes from version 1.5.0:
+ Misc new API, for appending a buffer to another, and for
comparing contents of two buffers for types of differences.
+ New "unsafe-to-break" API. 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 zaitor@opensuse.org

glyph..." This introduced memory access problems. To be fixed
properly soon.
* Tue Mar 07 2017 zaitor@opensuse.org

+ Implement OpenType Font Variation tables avar/fvar/HVAR/VVAR.
+ hb-shape and hb-view now accept --variations.
+ Various API additions.
* Sun Jan 08 2017 zaitor@opensuse.org
- Update to version 1.4.1:
+ Always build and use UCDN for Unicode data by default. 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 dimstar@opensuse.org

* Mon Apr 11 2016 zaitor@opensuse.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 zaitor@opensuse.org
- Update to version 1.2.5:
+ Fix GDEF mark-filtering-set, which was broken in 1.2.3.
* Fri Mar 18 2016 zaitor@opensuse.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 zaitor@opensuse.org
- 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 zaitor@opensuse.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 dimstar@opensuse.org
- 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 dimstar@opensuse.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 zaitor@opensuse.org
- 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 zaitor@opensuse.org
- Update to version 1.1.1:
+ Build fixes, specially for hb-coretext.
* Fri Nov 20 2015 mimi.vx@gmail.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 zaitor@opensuse.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.
This was changed in 1.0.5, but caused major issues, so revert.
- Changes from version 1.0.5:
+ Fix multiple memory access bugs discovered using libFuzzer.
+ Misc fixes.
+ New API:
- hb_font_set_parent().
- hb_ft_font_[sg]et_load_flags()
The default flags for fonts created using hb_ft_font_create()
has changed to default to FT_LOAD_DEFAULT now. Previously it
was defaulting to FT_LOAD_DFEAULT|FT_LOAD_NO_HINTING.
+ API changes:
- Fonts now default to units-per-EM as their scale, instead
of 0.
- hb_font_create_sub_font() does NOT make parent font immutable
anymore. hb_font_make_immutable() does.
* Fri Oct 09 2015 zaitor@opensuse.org
- Update to version 1.0.4:
+ Fix minor out-of-bounds read error.

+ Uniscribe positioning fix.
- Changes from version 1.0.2:
+ Fix shaping with cluster-level > 0.
+ Fix Uniscribe backend font-size scaling.
+ Declare dependencies in harfbuzz.pc. FreeType is not declared
though, to avoid bugs in pkg-config 0.26 with recursive
dependencies.
+ Slightly improved debug infrastructure. More to come later.
+ Misc build fixes.
- Changes from version 1.0.1:
+ Fix out-of-bounds access in USE shaper.
- Changes from version 1.0.0:
+ Implement Universal Shaping Engine:
https://www.microsoft.com/typography/OpenTypeDev/USE/intro.htm

+ Fix hb_language_t in language bindings.
+ Misc fixes.
* Tue May 05 2015 fstrba@suse.com
- Revert the introduction of harfbuzz-bootstrap: it did not help to
work around the cycle.
* Mon Apr 27 2015 dimstar@opensuse.org
- Add this-is-only-for-build-envs requires to the -bootstrap

* Thu Aug 21 2014 hrvoje.senjan@gmail.com
- Update to version 0.9.35:
+ Fix major shape-plan caching bug when more than one shaper
were provided to hb_shape_full() (as exercised by XeTeX).
+ Fix Arabic fallback shaping regression.
+ Major hb-coretext fixes. That backend is complete now,
including respecing buffer direction and language, down to
vertical writing.
+ Build fixes for Windows CE.

fdo#82246
- Mandaic had errors in its Unicode Joining_Type.
fdo#82306
+ API changes:
- hb_buffer_clear_contents() does not reset buffer flags now.
- Changes from version 0.9.34:
+ hb_feature_from_string() now accepts CSS
font-feature-settings format.
+ As a result, hb-shape / hb-view --features also accept
CSS-style strings. Eg, "'liga' off" is accepted now.
+ Add old-spec Myanmar shaper: fdo#81775
+ Don't apply 'calt' in Hangul shaper.
+ Fix mark advance zeroing for Hebrew shaper: fdo#76767
+ Implement Windows-1256 custom Arabic shaping.
Only built on Windows, and requires help from get_glyph().
+ Disable 'liga' in vertical text.
+ Build fixes.
+ API changes:
- Make HB_BUFFER_FLAG_BOT/EOT easier to use.

valid Unicode after hb_buffer_add_utf8/16/32 no matter how
broken the input is.
+ Fix Mongolian Variation Selectors for fonts without GDEF.
+ Fix minor invalid buffer access.
+ Accept zh-Hant and zh-Hans language tags.
hb_ot_tag_to_language() now uses these instead of private tags.
+ Build fixes.
+ New API:
- hb_buffer_add_codepoints(). This does what
hb_buffer_add_utf32() used to do, ie. no validity check on
the input at all. add_utf32 now replaces invalid Unicode
codepoints with the replacement character.
- hb_buffer_set_replacement_codepoint()
- hb_buffer_get_replacement_codepoint()
Previously, in hb_buffer_add_utf8 and hb_buffer_add_utf16,
when we detected broken input, we replaced that with
(hb_codepoint_t)-1. This has changed to use U+FFFD now, but
can be changed using these new API.
* Fri Jul 11 2014 dimstar@opensuse.org
- Update to version 0.9.30:
