2.3.95

Match 'Standard Symbols L' for 'Symbol'.  Add URW fonts as aliases for
all of the PostScript fonts.  (reported by Miguel Rodriguez).  Fix a
number of Coverity defects (Frederic Crozat).  Speed up FcFontSort
(fix suggested by Kenichi Handa).  Fix error with charsets.  Survive
missing docbook2pdf.  Compile on HP-UX, AIX, SGI and Windows (Cygwin,
MinGW).  Fix intel compiler warnings.  Fix multiarch support (don't
destroy multiarch files!)  Require pkg-config.  (Thanks Behdad; better
solution wanted for libxml2 detection!)  Fix typos in orth files and
add orth for Lingala (reported by Denis Jacquerye).  Remove debian/
directory.  Add a configuration file that disables hinting for the
Lohit Gujarati font (since the hinting distorts some glyphs quite
badly).  Sort directory entries while scanning them from disk;
prevents Heisenbugs due to file ordering in a directory (due to Egmont
Koblinger).  Fix Wine's problem with finding fonts.  (Reported by
Bernhard Rosenkraenzer.)  Fix the issues with GNU libiconv vs. libc
iconv (which especially appear on Solarii); patch by Behdad Esfahbod,
approach suggested by Tim Mooney.

2.3.94

fc-cat can take directories as input and creates old-style fonts.cache
listings.
fc-cache takes -r --really-force which blows away all old caches and
regenerates.
Robustness fixes, integer overflow fixes (notably to cache handling
code), toast broken global cache files.
Change binary format to make it compatible with static langset
information (thanks to Takashi Iwai).
Open hashed caches before fonts.cache-2 (Takashi Iwai).
Fix FcFontSetMatch's algorithm, which used to unjustly kill fonts for
not declaring certain elements (Takashi Iwai).
Fix matching bug when multiple elements match; don't use
the sum of all scores, but the best score (James Su).
Make fc-lang more friendly to Windows systems.
Remove archaic chars from Georgian charset; add Euro character to
charsets for European languages.
Fix treatment of broken PCF fonts that don't declare family names.
Pass O_BINARY to open if appropriate (reported by Doodle).
Normalize font directories to the form in which they appear in 
config files.  
Add a record of the cached directory to the cache file.
Perf optimizations (Dirk Mueller; some reported by Michael Meeks.)
Don't loop infinitely on recursive symlinks.
Make 'make distcheck' work with automake 1.6.3.
Replace 'stamp' target with mkinstalldirs.
Don't stop scanning if a directory in fonts.conf doesn't exist,
because subsequent directories might exist.
Put directory names into global cache (reported by Ronny V. Vindenes).
Treat zh-hk fonts differently from zh-tw fonts.  This patch may cause
fontconfig to treat A-X fonts differently from A-Y fonts; please mail
the fontconfig list if this causes any problems.
Fix for unaligned memory accesses (Andreas Schwab).
Fix treatment of cache directory as read from cache file; don't use
string equality to determine if we have the right file, use inode
equality.
Properly skip past dir caches that contain zero fonts, as occurs
in global caches (reported by Mike Fabian).
Print out full pathname in fc-match -v (reported by Frederic Crozat).
Fix bug where fc-match crashes when given __DUMMY__ property to
match on.

2.3.93

Create cache files in /var/cache/fontconfig with hashed filenames, if
possible, for added FHS compliance.  
Make fc-cat read both per-directory and global cache files.  
Add config file for Persian fonts from Sharif FarsiWeb, Inc.  
Major performance improvements by Dirk Mueller, Stephen Kulow, and Michael Matz at SuSE: in particular, speed up FcFontSetMatch, and inline many functions.
Fix treatment of globs in config files, broken since 2.3.2 and discovered by Mathias Clasen.
Don't use freetype internal headers (patch by Matthias Clasen).  
Further space improvements: create langsets statically, so that they can live in .rodata.
Properly align mmapped data structures to make e.g. ia64 happy.  
Bug fixes.

2.3.92

Fix corrupted caches bugs from 2.3.91 (reported by Mike Fabian).
Store only basename in the cache, reconstitute on demand 
(reported by James Cloos).
Change the rule for artificial emboldening in fonts.conf.in.  This
enables the support for artificial emboldening included in cairo
(patch by Zhe Su).
Add FC_EMBEDDED_BITMAP object type to tell Xft/Cairo whether
to load embedded bitmaps or not (patch by Jinghua Luo).
Fix GCC4 warnings (some by Behdad Esfahbod).
Support localized font family and style names; this has been reported
to break old apps like xfd, but modern (gtk+/qt/mozilla) apps work
fine (patch by Zhe Su).
Prevent fc-list from escaping strings when printing them (reported by
Matthias Clasen).
Add valist sentinel markup for FcObjectSetBuild and 
FcPatternBuild (patch by Marcus Meissner).
Add consts to variables so as to move arrays into .rodata (patch by
Ross Burton).
Modify config file to use Greek fonts before Asian fonts with
Greek glyphs. (patch by Simos Xenitellis).
Use libtool -no-undefined flag on all platforms (patch by Christian
Biesinger).

2.3.91

Use libxml2 if requested or if expat not available. (Mathias Hasselmann)
Fix multi-arch cache files: compute the position for the
block to be added using info from OrigFile, not NewFile. (plam)
Cast results of sizeof() to unsigned int to get rid of
warnings on x86_64 (reported by Matthias Clasen).
Use FcAtomic to rewrite cache files; don't unlink the fonts.cache-2
file even if there's no data to write; just write an empty cache file.
(Reported by Lubos Lunak)
Allocate room for the subdirectory names in each directory cache. 
(Reported by James Cloos)

2.3.90

Development release of mmap patch: load pattern information
directly from cache files.  (Patrick Lam)

2.3.2

Patch memory leaks in using iconv.  (Reported by Chris Capoccia)
Patch memory leaks in fc-cache. (Reported by Chris Capoccia)
Fetch bitmap glyphs to get widths during font evaluation. (keithp)

Include debian packaging stuff in CVS (Josselin Mouette)
Add more conf.d examples (Keith Packard)
Make manuals build again (Keith Packard)
Johap -> Johab (Funda Wang)

2.3.0

Fix memory leak of patterns rejected by configuration (#2518)

Create prototype /etc/fonts/conf.d directory and populate it with a few
sample files.  These samples are unused as the file names don't start with
numbers.

Update documentation.

2.2.99

Verify cache for FC_FILE and FC_FAMILY in every entry (#2219)

Update blanks list from recent Unicode docs (#86)

Various small build fixes (#280, #2278, 

Documentation fixes (#2085, #2284, #2285)

(Keith Packard)

Remove Han characters from Korean orthography (Tor Andersson)

2.2.97

Fc-cache sleeps before exiting to ensure filesystem timestamps are well
ordered.

Added Punjai orthography.

The timestamp in fonts.conf is gone now.  Too many problems.

The default font path includes all of the X fonts; use selectfont/rejectfont
to eliminate bitmaps, as shown in the sample local.conf file.

<include> configuration elements may now reference a directory.  Files
in that directory matching [0-9]* are loaded in UTF-8 collating sequence order.

<selectfont> configuration added to control which fonts are used.

fontformat font pattern elements built from the FT_Get_X11_Font_Format
function in newer versions of FreeType.

'capability' list constructed from gsub/gpos and silf values in TrueType
files.

Multi-lingual names (style, family, fullname) extracted and stored with
parallel <foo>lang properties marking language.

2.2.96

Fix FcConfigUpToDate to actually check all font directories and eliminate
a typo which completely prevented it from working (Lubos Lunak
<l.lunak@suse.cz>)

Remove comma at end of FcResult enum definition for picky compilers.

2.2.95

Add FcResultOutOfMemory so FcFontSetMatch can return accurate error.

Replace MIN/MAX/ABS macros which happened to be in old FreeType releases
with FC_MIN/FC_MAX/FC_ABS macros owned by fontconfig.

2.2.94

The 2.2.93 release was prepared with a broken libtool which created
the shared library without the '.so' in the file names.

2.2.93

This is the third prerelease of fontconfig 2.3.  Significant changes from
2.2.92 are:

 o	Use new FreeType #include syntax
 o	use y_ppem field instead of 'height' in bitmap sizes rec -
 	FreeType changed the semantics.  Still uses height for
	older versions of FreeType
 o	Don't construct program manuals unless docbook is available

2.2.92

 o	make distcheck work

2.2.91

 o	Switch to SGML manuals
 o	Add FC_DUAL width spacing value
 o	Add FcFini to close out fontconfig and release all memory
 
2.2

This is the third public release of fontconfig, a font configuration and
customization library.  Fontconfig is designed to locate fonts within the
system and select them according to requirements specified by applications.

Fontconfig is not a rasterization library, nor does it impose a particular
rasterization library on the application.  The X-specific library
'Xft' uses fontconfig along with freetype to specify and rasterize fonts.
