-CHANGES BETWEEN 2.12.0 and 2.12.1
+CHANGES BETWEEN 2.12.1 and 2.13.0 (2023-Feb-09)
+
+  I. IMPORTANT CHANGES
+
+  - The demo program `ftinspect` has  been completely updated and much
+    enhanced.  It now  combines the functionality of  almost all other
+    graphical FreeType  demo programs into a  single application based
+    on the Qt framework.  This was Charlie Jiang's GSoC 2022 project.
+
+  - The 'COLR' v1 API is now considered as stable.
+
+      https://learn.microsoft.com/en-us/typography/opentype/spec/colr
+
+
+  III. MISCELLANEOUS
+
+  - For  OpenType  Variable Fonts,  `avar`  table  format 2.0  is  now
+    supported.  The code was contributed by Behdad Esfahbod.
+
+    Note that this is an extension supported on recent Apple platforms
+    and by HarfBuzz, but not yet in the OpenType standard!  See
+
+      https://github.com/harfbuzz/boring-expansion-spec/blob/main/avar2.md
+
+    for the specification.  To deactivate it, define the configuration
+    macro 'TT_CONFIG_OPTION_NO_BORING_EXPANSION'.
+
+  - A new API  `FT_GlyphSlot_Slant` to slant a glyph by  a given angle
+    has been added.   Note that this function is  part of `ftsynth.h`,
+    which is still considered to be in alpha stage.
+
+  - TrueType interpreter version 38  (also known as 'Infinality') that
+    was first introduced about 10 years  ago in FreeType 2.4.11 is now
+    deprecated and slated to be removed in the next version.  TrueType
+    interpreter version 40 has been FreeType's default version for six
+    years now and provides an excellent alternative.  This is the last
+    FreeType     version     with    TT_INTERPRETER_VERSION_38     and
+    TT_INTERPRETER_VERSION_40 treated differently.
+
+  - The  only  referenced  but never  documented  configuration  macro
+    `FT_CONFIG_OPTION_NO_GLYPH_NAMES` has been removed.
+
+  - The `ftbench` demo  program got a new command line  option `-e` to
+    set a charmap index.
+
+  - Specifying  a point  size is  now optional  for the  demo programs
+    `ftgrid`, `ftmulti`,  `ftstring`, and  `ftview`.  If not  given, a
+    default size is used.
+
+  - For  `ftgrid`,  `ftstring`, and  `ftview`,  option  `-e` now  also
+    accepts a numeric value to set a charmap index.
+
+  - In  `ftstring`, it  is  now  possible to  set  the displayed  text
+    interactively by pressing the 'Enter' key.
+
+  - `ftmulti` can now handle up to 16 design axes.
+
+  - To  avoid  reserved identifiers  that  are  globally defined,  the
+    auto-hinter  debugging   macros  (which  are  only   available  if
+    `FT_DEBUG_AUTOFIT` is defined)
+
+    ```
+    _af_debug_disable_horz_hints
+    _af_debug_disable_vert_hints
+    _af_debug_disable_blue_hints
+    _af_debug_hints
