-Overview of changes leading to 1.2.7
-Monday, May 2, 2016
-====================================
-
-- 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.
-
-
-Overview of changes leading to 1.2.6
-Friday, April 8, 2016
-====================================
-
-- 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.
-
-
-Overview of changes leading to 1.2.5
-Monday, April 4, 2016
-====================================
-
-- Fix GDEF mark-filtering-set, which was broken in 1.2.3.
-
-
-Overview of changes leading to 1.2.4
-Thursday, March 17, 2016
-====================================
-
-- Synthesize GDEF glyph class for any glyph that does not have one in GDEF.
- I really 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. However, I also reduced the
- overhead of those checks, so it's a non-issue right now. You can
- forget it. Just not defining anything at all is fine.
-
-
-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 1.2.1
-Tuesday, February 23, 2016
-====================================
-

-- Add test/shaping/README.md about how to add tests to the suite.
-
-
-Overview of changes leading to 1.2.0
-Friday, February 19, 2016
-====================================
-
-- 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. See:
- https://github.com/behdad/harfbuzz/issues/211
- https://github.com/behdad/harfbuzz/commit/86c68c7a2c971efe8e35b1f1bd99401dc8b688d2
-- Graphite2 shaper: improved negative advance handling (eg. Nastaliq).
-- Add nmake-based build system for Windows.
-- Minor speedup.
-- Misc. improvements.
-
-
-Overview of changes leading to 1.1.3
-Monday, January 11, 2016
-====================================
-
-- 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, thanks to Ebrahim Byagowi.
-- Misc bug fixes.
-- New API:
-
- * Font extents:
- hb_font_extents_t
- hb_font_get_font_extents_func_t
- hb_font_get_font_h_extents_func_t
- hb_font_get_font_v_extents_func_t
- hb_font_funcs_set_font_h_extents_func
- hb_font_funcs_set_font_v_extents_func
- hb_font_get_h_extents
- hb_font_get_v_extents
- hb_font_get_extents_for_direction
-
- * Buffer message (aka debug):
- hb_buffer_message_func_t
- hb_buffer_set_message_func()
- Actual message protocol to be fleshed out later.
-
-
-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
-====================================
-

-====================================
-
-- 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().
-
-
-Overview of changes leading to 1.0.6
-Thursday, October 15, 2015
-====================================
-
-- Reduce max nesting level in OT lookups from 8 to 6.
- Should not affect any real font as far as I know.
-- 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
- last release (1.0.5), but caused major issues, so revert.
- https://github.com/behdad/harfbuzz/issues/143
-
-
-Overview of changes leading to 1.0.5
-Tuesday, October 13, 2015
-====================================
-
-- Fix multiple memory access bugs discovered using libFuzzer.
- https://github.com/behdad/harfbuzz/issues/139
- Everyone should upgrade to this version as soon as possible.
- We now have continuous fuzzing set up, to avoid issues like
- these creeping in again.
-- 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.
