Overview of changes leading to 2.6.7
Wednesday, June 3, 2020

• Update to Unicode 13.0.0.
• Fix hb_ot_layout_get_ligature_carets for fonts without lcar table, it was
  completely broken for all the other fonts since 2.1.2.
• As a part of our migration to meson, this release will be the last one
  to provide cmake port files but autotools still is our main build system.
  There is a possibility that the next version or the after be released
  using meson.
