They provad a new API (FT_Get_X11_Font_Format) an X11-compatible
string describing the font format of a given face. This was put in
a new optional base source file, corresponding to a new public
header (named FT_XFREE86_H since this function should only be used
within the XFree86 font server IMO).

I. IMPORTANT BUG FIXES
- the 'version_info' returned by "freetype-config" in 2.1.0 returned an
invalid value. It now returns 9:1:3 (2.0.9 returned 9:0:3)
- The `version_info' returned by `freetype-config' in 2.1.0 returned an
invalid value. It now returns 9:1:3 (2.0.9 returned 9:0:3).
- 2.1.0 couldn't be linked against applications on Win32 and Amiga
systems, due to a new debug function that wasn't properly propagated
to the system-specific directory in 'builds'.
- Version 2.1.0 couldn't be linked against applications on Win32 and
Amiga systems due to a new debug function that wasn't properly
propagated to the system-specific directory in `builds'.
- various MacOS and Mac OS X specific fixes
- Various MacOS and Mac OS X specific fixes.
- fixed a bug in the TrueType charmap validation routines that made
2.1.0 over-restrictive over the fonts it could accept.
- Fixed a bug in the TrueType charmap validation routines that made
version 2.1.0 too restrictive -- many popular fonts have been
rejected.
- surprisingly, there was still a very small difference between the
monochrome glyph bitmaps produced by FT 1.x and FT 2.x with the
bytecode interpreter enabled. This was caused by an invalid flag
setting in the TrueType glyph loader that caused the rasterizer to
change its drop-out control mode. This is now fixed, and results
should _really_ be 100% identical
- There was still a very small difference between the monochrome glyph
bitmaps produced by FreeType 1.x and FreeType 2.x with the bytecode
interpreter enabled. This was caused by an invalid flag setting in
the TrueType glyph loader, making the rasterizer change its drop-out
control mode. Now theresults should _really_ be completely identical.
- the TrueType name table loader has been improved to support many
popular though buggy Asian fonts. It now ignores empty name entries,
invalid pointer offsets and a few other sad things. Moreover, name
strings are now loaded on demand, which reduces the memory load of
many faces (e.g. the ARIAL.TTF font file contains a 10Kb name table
containing 70 names)

- Fixed a bug in the Postscript hinter that prevented family blues
substitution to happen correctly.
II. NEW FEATURES
- Three new font drivers in this release !!
- Three new font drivers in this release:
* a BDF font driver, contributed by Franco Narda Zapelli, and
heavily modified by Werner Lemberg, it also supports anti-aliased
bitmaps
* A BDF font driver, contributed by Franco Narda Zapelli, heavily
modified by Werner Lemberg. It also supports anti-aliased bitmaps
(using a slightly extended BDF format).
* a Type42 font driver, contributed by ..... This one is still
experimental but seems to work relatively well but lacks some
charmap support for now
* a PFR font driver, contributed by David Turner himself. It doesn't
support PFR hinting Beware that BitStream has at least two patents
on this format !!
* A Type42 font driver, contributed by Roberto Alameda. It is
still experimental but seems to work relatively well. Currently,
charmap support is not fully implemented.
* A PFR font driver, contributed by David Turner himself. It doesn't
support PFR hinting -- note that BitStream has at least two patents
on this format!
