+Overview of changes leading to 2.0.0
+Wednesday, October 17, 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.
+

++HB_FEATURE_GLOBAL_START
++HB_FEATURE_GLOBAL_END
++hb_buffer_set_invisible_glyph()
