+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.
+
