   - Increased  precision  while  computing  OpenType  font   variation
     instances.

+
+  - The `ftmulti' demo program now  supports multiple hidden axes with
+    the same name tag.
+
+  - `ftview', `ftstring', and `ftgrid' got  a `-k' command line option
+    to emulate a sequence of keystrokes at start-up.
+
+  - `ftview', `ftstring', and `ftgrid' now support screen dumping to a
+    PNG file.
+
+  - The bytecode debugger, `ttdebug',  now supports variation TrueType
+    fonts; a variation font instance can be selected with the new `-d'
+    command line option.
