Overview of changes leading to 2.3.1
Wednesday, January 30, 2019
====================================
- AAT bug fixes.
- Misc internal housekeeping cleanup.

Log message:
harfbuzz: Fix build on SunOS where int8_t is not explicitly "signed".

Log message:
Update harfbuzz to 2.3.0.

-   Fix regression on big-endian architectures. Ouch!
-   Misc bug and build fixes.
-   Fix subsetting of simple GSUB/GDEF.
-   Merge CFF / CFF2 support contributed by Adobe. This mostly involves
    the subsetter, but also get_glyph_extents on CFF fonts.

Log message:
Add GCC_REQD+=4.9, so that this builds on NetBSD/i386 7.1 again.
For newer OSes this would be a no-op, so no revision bump.

Log message:
revbump after updating textproc/icu

Saturday, October 20, 2018
====================================
- Fix two minor memory access issues in AAT tables.

Overview of changes leading to 2.0.1
Friday, October 19, 2018
====================================
- Fix hb-version.h reported release version that went wrong (1.8.0)
  with previous release.
- Fix extrapolation in 'trak' table.
- Fix hb-font infinite-recursion issue with some font funcs and
  subclassed fonts.
- Implement variation-kerning format in kerx table, although without
  variation.
- Fix return value of hb_map_is_empty().

Overview of changes leading to 2.0.0
Thursday, October 18, 2018
====================================
- Added AAT shaping support (morx/kerx/trak).
  Automatically used if GSUB/GPOS are not available respectively.
  Set HB_OPTIONS=aat env var to have morx/kerx preferred over
  GSUB/GPOS.
- Apply TrueType kern table internally, instead of relying on
  hb_font_t callbacks.
- Khmer shaper significantly rewritten to better match Uniscribe.
- Indic3 tags ('dev3', etc) are passed to USE shaper.
- .dfont Mac font containers implemented.
- Script- and language-mapping revamped to better use BCP 47.
- Misc USE and Indic fixes.
- Misc everything fixes.
- Too many things to list.  Biggest release since 0.9.1, with
  over 500 commits in just over 5 weeks!  Didn't intend it to
  be a big release.  Just happened to become.
- hb-ft now locks underlying FT_Face during use.

API changes:

- Newly-created hb_font_t's now have our internal "hb-ot-font"
  callbacks set on them, so they should work out of the box
  without any callbacks set.  If callbacks are set, everything
  is back to what it was before, the fallback callbacks are
  null.  If you to get the internal implementation modified,
  sub_font it.

- New hb_font_funcs_set_nominal_glyphs_func() allows speeding
  up character to glyph mapping.

New API:
+HB_FEATURE_GLOBAL_START
+HB_FEATURE_GLOBAL_END
+hb_buffer_set_invisible_glyph()
+hb_buffer_get_invisible_glyph()
+hb_font_funcs_set_nominal_glyphs_func()
+hb_ot_layout_table_select_script()
+hb_ot_layout_script_select_language()
+hb_ot_layout_feature_get_name_ids()
+hb_ot_layout_feature_get_characters()
+hb_name_id_t
+HB_NAME_ID_INVALID
+HB_OT_MAX_TAGS_PER_SCRIPT
+hb_ot_tags_from_script_and_language()
+hb_ot_tags_to_script_and_language()

Overview of changes leading to 1.9.0
Monday, September 10, 2018
====================================
- Added 'cmap' API to hb_face_t.
- Face-builder API.
- hb-ot-font re-creation should be much leaner now, as the
  font tables it uses are cached on hb_face_t now.
- Internal source header file name changes:
  hb-*-private.hh is renamed to hb-*.hh.

New API:
+HB_UNICODE_MAX
+hb_face_collect_unicodes()
+hb_face_collect_variation_selectors()
+hb_face_collect_variation_unicodes()
+hb_face_builder_create()
+hb_face_builder_add_table()
