CHANGES BETWEEN 2.10.0 and 2.10.1

I. IMPORTANT BUG FIXES

  • The bytecode hinting of OpenType variation fonts was flawed, since
    the data in the `CVAR' table wasn't correctly applied.

II. MISCELLANEOUS

  • Auto-hinter support for Mongolian.

  • For distribution, .tar.bz2' packages are replaced with.tar.xz'
    bundles.

  • The handling of the default character in PCF fonts as introduced
    in version 2.10.0 was partially broken, causing premature abortion
    of charmap iteration for many fonts.

  • If `FT_Set_Named_Instance' was called with the same arguments
    twice in a row, the function returned an incorrect error code the
    second time.

  • Direct rendering using FT_RASTER_FLAG_DIRECT crashed (bug
    introduced in version 2.10.0).

  • Increased precision while computing OpenType font variation
    instances.

  • The flattening algorithm of cubic Bezier curves was slightly
    changed to make it faster. This can cause very subtle rendering
    changes, which aren't noticeable by the eye, however.

  • The auto-hinter now disables hinting if there are blue zones
    defined for a `style' (i.e., a certain combination of a script and
    its related typographic features) but the font doesn't contain any
    characters needed to set up at least one blue zone.

  • 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.
