   6 Check INSTALL for compilation and installation instructions.
   7 Report bugs to https://bugs.freedesktop.org in the fontconfig module.

   9 2.3.94
  10
  11 fc-cat can take directories as input and creates old-style fonts.cache
  12 listings.
  13 fc-cache takes -r --really-force which blows away all old caches and
  14 regenerates.
  15 Robustness fixes, integer overflow fixes (notably to cache handling
  16 code), toast broken global cache files.
  17 Change binary format to make it compatible with static langset
  18 information (thanks to Takashi Iwai).
  19 Open hashed caches before fonts.cache-2 (Takashi Iwai).
  20 Fix FcFontSetMatch's algorithm, which used to unjustly kill fonts for
  21 not declaring certain elements (Takashi Iwai).
  22 Fix matching bug when multiple elements match; don't use
  23 the sum of all scores, but the best score (James Su).
  24 Make fc-lang more friendly to Windows systems.
  25 Remove archaic chars from Georgian charset; add Euro character to
  26 charsets for European languages.
  27 Fix treatment of broken PCF fonts that don't declare family names.
  28 Pass O_BINARY to open if appropriate (reported by Doodle).
  29 Normalize font directories to the form in which they appear in
  30 config files.
  31 Add a record of the cached directory to the cache file.
  32 Perf optimizations (Dirk Mueller; some reported by Michael Meeks.)
  33 Don't loop infinitely on recursive symlinks.
  34 Make 'make distcheck' work with automake 1.6.3.
  35 Replace 'stamp' target with mkinstalldirs.
  36 Don't stop scanning if a directory in fonts.conf doesn't exist,
  37 because subsequent directories might exist.
  38 Put directory names into global cache (reported by Ronny V. Vindenes).
  39 Treat zh-hk fonts differently from zh-tw fonts.  This patch may cause
  40 fontconfig to treat A-X fonts differently from A-Y fonts; please mail
  41 the fontconfig list if this causes any problems.
  42 Fix for unaligned memory accesses (Andreas Schwab).
  43 Fix treatment of cache directory as read from cache file; don't use
  44 string equality to determine if we have the right file, use inode
  45 equality.
  46 Properly skip past dir caches that contain zero fonts, as occurs
  47 in global caches (reported by Mike Fabian).
  48 Print out full pathname in fc-match -v (reported by Frederic Crozat).
  49 Fix bug where fc-match crashes when given __DUMMY__ property to
  50 match on.
  51
  52 2.3.93
  53
  54 Create cache files in /var/cache/fontconfig with hashed filenames, if
  55 possible, for added FHS compliance.
  56 Make fc-cat read both per-directory and global cache files.
  57 Add config file for Persian fonts from Sharif FarsiWeb, Inc.
  58 Major performance improvements by Dirk Mueller, Stephen Kulow, and Michael Matz at SuSE: in particular, speed up FcFontSetMatch, and inline many functions.
  59 Fix treatment of globs in config files, broken since 2.3.2 and discovered by Mathias Clasen.
  60 Don't use freetype internal headers (patch by Matthias Clasen).
  61 Further space improvements: create langsets statically, so that they can live in .rodata.
  62 Properly align mmapped data structures to make e.g. ia64 happy.
  63 Bug fixes.
  64
  65 2.3.92
  66
  67 Fix corrupted caches bugs from 2.3.91 (reported by Mike Fabian).
  68 Store only basename in the cache, reconstitute on demand
  69 (reported by James Cloos).
  70 Change the rule for artificial emboldening in fonts.conf.in.  This
  71 enables the support for artificial emboldening included in cairo
  72 (patch by Zhe Su).
  73 Add FC_EMBEDDED_BITMAP object type to tell Xft/Cairo whether
  74 to load embedded bitmaps or not (patch by Jinghua Luo).
  75 Fix GCC4 warnings (some by Behdad Esfahbod).
  76 Support localized font family and style names; this has been reported
  77 to break old apps like xfd, but modern (gtk+/qt/mozilla) apps work
  78 fine (patch by Zhe Su).
  79 Prevent fc-list from escaping strings when printing them (reported by
  80 Matthias Clasen).
  81 Add valist sentinel markup for FcObjectSetBuild and
  82 FcPatternBuild (patch by Marcus Meissner).
  83 Add consts to variables so as to move arrays into .rodata (patch by
  84 Ross Burton).
  85 Modify config file to use Greek fonts before Asian fonts with
  86 Greek glyphs. (patch by Simos Xenitellis).
  87 Use libtool -no-undefined flag on all platforms (patch by Christian
  88 Biesinger).
  89
  90 2.3.91
  91
  92 Use libxml2 if requested or if expat not available. (Mathias Hasselmann)
  93 Fix multi-arch cache files: compute the position for the
  94 block to be added using info from OrigFile, not NewFile. (plam)
  95 Cast results of sizeof() to unsigned int to get rid of
  96 warnings on x86_64 (reported by Matthias Clasen).
  97 Use FcAtomic to rewrite cache files; don't unlink the fonts.cache-2
  98 file even if there's no data to write; just write an empty cache file.
  99 (Reported by Lubos Lunak)
 100 Allocate room for the subdirectory names in each directory cache.
 101 (Reported by James Cloos)
 102
 103 2.3.90

 126 Fix memory leak of patterns rejected by configuration (#2518)
 127
 128 Create prototype /etc/fonts/conf.d directory and populate it with a few

 130 numbers.

 165
 166 Fc-cache sleeps before exiting to ensure filesystem timestamps are well
 167 ordered.
 168
 169 Added Punjai orthography.
 170
 171 The timestamp in fonts.conf is gone now.  Too many problems.
 172
 173 The default font path includes all of the X fonts; use selectfont/rejectfont
 174 to eliminate bitmaps, as shown in the sample local.conf file.
 175
 176 <include> configuration elements may now reference a directory.  Files
 177 in that directory matching [0-9]* are loaded in UTF-8 collating sequence order.
 178
 179 <selectfont> configuration added to control which fonts are used.
 180
 181 fontformat font pattern elements built from the FT_Get_X11_Font_Format

 189
 190 2.2.96
 191
 192 Fix FcConfigUpToDate to actually check all font directories and eliminate
 193 a typo which completely prevented it from working (Lubos Lunak
 194 <l.lunak@suse.cz>)
 195
 196 Remove comma at end of FcResult enum definition for picky compilers.
 197
 198 2.2.95
 199
 200 Add FcResultOutOfMemory so FcFontSetMatch can return accurate error.
 201
 202 Replace MIN/MAX/ABS macros which happened to be in old FreeType releases
 203 with FC_MIN/FC_MAX/FC_ABS macros owned by fontconfig.
 204
 205 2.2.94
 206
 207 The 2.2.93 release was prepared with a broken libtool which created
 208 the shared library without the '.so' in the file names.
 209
 210 2.2.93
 211
 212 This is the third prerelease of fontconfig 2.3.  Significant changes from
 213 2.2.92 are:
 214
 215  o      Use new FreeType #include syntax
 216  o      use y_ppem field instead of 'height' in bitmap sizes rec -
 217         FreeType changed the semantics.  Still uses height for
 218         older versions of FreeType
 219  o      Don't construct program manuals unless docbook is available
 220
 221 2.2.92
 222
 223  o      make distcheck work
 224
 225 2.2.91
 226
 227  o      Switch to SGML manuals
 228  o      Add FC_DUAL width spacing value
 229  o      Add FcFini to close out fontconfig and release all memory
 230
 231 2.2
 232
 233 This is the third public release of fontconfig, a font configuration and
 234 customization library.  Fontconfig is designed to locate fonts within the
 235 system and select them according to requirements specified by applications.
 236
 237 Fontconfig is not a rasterization library, nor does it impose a particular
 238 rasterization library on the application.  The X-specific library
 239 'Xft' uses fontconfig along with freetype to specify and rasterize fonts.
