Overview of changes leading to 1.2.3
Thursday, February 25, 2016
====================================
- 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.
Overview of changes leading to 1.2.2
Wednesday, February 24, 2016
====================================
- 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.

Overview of changes leading to 1.1.3
Monday, January 11, 2016
====================================
- Ported Indic shaper to Unicode 8.0 data.
- Universal Shaping Engine fixes.

Overview of changes leading to 1.1.2
Wednesday, November 26, 2015
====================================
- Fix badly-broken fallback shaper that affected terminology.
https://github.com/behdad/harfbuzz/issues/187
- 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.
Overview of changes leading to 1.1.1
Wednesday, November 24, 2015
====================================
- Build fixes, specially for hb-coretext.

Overview of changes leading to 1.1.0
Wednesday, November 18, 2015
====================================
- Implement 'stch' stretch feature for Syriac Abbreviation Mark.
https://github.com/behdad/harfbuzz/issues/141
- Disable use of decompose_compatibility() callback.
- Implement "shaping" of various Unicode space characters, even
if the font does not support them.
https://github.com/behdad/harfbuzz/issues/153
- 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().

version.h is listed both in pkginclude_HEADERS (via $HBHEADERS) and
nodist_pkginclude_HEADERS. This double listing is likely cause of
the make install error:
/usr/bin/install: cannot create regular file `.../harfbuzz/0.9.10-r0/image/usr/include/harfbuzz/hb-version.h': File exists
Just remove the nodist_pkginclude_HEADERS entry. We're not creating
the tarball, and listing version.h here wouldn't prevent the other
listing from including it to tarball anyway.

OpenType text shaping engine HarfBuzz is dependency of pango >= 1.32
This depends on all of glib-2.0, cairo, and freetype to consistently
provide all backends. Otherwise it would, in typical case, depend
on build order of these packages. HarfBuzz configure would pick those
backends for which dependencies happen to be built before it.
Similarly graphite is consistenly disabled if there ever happens
to be recipe for it.
