  12 Keith Packard:
  13       Make path names in cache files absolute (NB, cache format change) Stop
  14       Eliminate pattern freezing
  15       Add .gitignore
  16       Construct short architecture name from architecture signature.
  17       Write caches to first directory with permission. Valid cache in FcDirCacheOpen.
  18       Eliminate NormalizeDir. Eliminate gratuitous stat/access calls per dir.
  19       Add architecture to cache filename.
  20       Eliminate global cache. Eliminate multi-arch cache code.
  21       Fix up fc-cache and fc-cat for no global cache changes.
  22       Eliminate ./ and ../ elements from font directory names when scanning.
  23       Regenerate x86 line in fcarch.tmpl.h to match change in cache data.
  24       Add x86-64 architecture and signature.
  25       During test run, remove cache directory to avoid stale cache usage.
  26       Add ppc architecture
  27       Revert to original FcFontSetMatch algorithm to avoid losing fonts.
  28       Rework cache files to use offsets for all data structures.
  29       Fix build problems caused by cache rework.
  30       FcCharSetSerialize was using wrong offset for leaves. Make fc-cat work.
  31       Rework Object name database to unify typechecking and object lookup.
  32       Skip broken caches. Cache files are auto-written, don't rewrite in fc-cache.
  33       Fix fc-cat again. Sigh.
  34       Use intptr_t instead of off_t inside FcCache structure.
  35       Serialized value lists were only including one value.
  36       Automatically remove invalid cache files.
  37       With no args, fc-cat now dumps all directories.
  38       Revert ABI changes from version 2.3
  39       Change $(pkgcachedir) to $(fc_cachedir) in fc-cat and fc-cache Makefile.am
  40       Allow FcTypeLangSet to match either FcTypeLangSet or FcTypeString.
  41       Remove stale architecture signatures.
  42       Pass directory information around in FcCache structure. Freeze charsets.
  43       Fix fc-lang to use new charset freezer API.
  44       Fontset pattern references are relative to fontset, not array.
  45       Add some ignores
  46       Only rebuild caches for system fonts at make install time.
  47       Fix memory leaks in fc-cache directory cleaning code.
  48       Add @EXPAT_LIBS@ to Libs.private in fontconfig.pc (bug 7683)
  49       Avoid #warning directives on non-GCC compilers. (bug 7683)
  50       Chinese/Macau needs the Hong Kong orthography instead of Taiwan (bug 7884)
  51       Add Assamese orthography (as.orth). Bug #8050
  52       Really only rebuild caches for system fonts at make install time.
  53       Fonts matching lang not territory should satisfy sort pattern lang.
  54       Prefer Bitstream Vera to DejaVu families.
  55       Guess that mac roman names with lots of high bits are actually SJIS.
  56       Document FC_DEBUG values (bug 6393). Document name \ escape syntax.
  57       Move Free family names to bottom of respective aliases. (bug 7429)
  58       Unify directory canonicalization into FcStrAddFilename.
  59       Allow font caches to contain newer version numbers
  60       Add FcMatchScan to resolve Delicious font matching issues (bug #6769)
  61       Fix missing initialization/destruction of new 'scan' target subst list.
  62       Don't segfault when string values can't be parsed as charsets or langsets.
  63       Using uninitialized (and wrong) variable in FcStrCopyFilename.
  64       Oops; missed the 60-delicious.conf file.

  73 2.3.95
  74
  75 Match 'Standard Symbols L' for 'Symbol'.  Add URW fonts as aliases for
  76 all of the PostScript fonts.  (reported by Miguel Rodriguez).  Fix a
  77 number of Coverity defects (Frederic Crozat).  Speed up FcFontSort
  78 (fix suggested by Kenichi Handa).  Fix error with charsets.  Survive
  79 missing docbook2pdf.  Compile on HP-UX, AIX, SGI and Windows (Cygwin,
  80 MinGW).  Fix intel compiler warnings.  Fix multiarch support (don't
  81 destroy multiarch files!)  Require pkg-config.  (Thanks Behdad; better
  82 solution wanted for libxml2 detection!)  Fix typos in orth files and
  83 add orth for Lingala (reported by Denis Jacquerye).  Remove debian/
  84 directory.  Add a configuration file that disables hinting for the
  85 Lohit Gujarati font (since the hinting distorts some glyphs quite
  86 badly).  Sort directory entries while scanning them from disk;
  87 prevents Heisenbugs due to file ordering in a directory (due to Egmont
  88 Koblinger).  Fix Wine's problem with finding fonts.  (Reported by
  89 Bernhard Rosenkraenzer.)  Fix the issues with GNU libiconv vs. libc
  90 iconv (which especially appear on Solarii); patch by Behdad Esfahbod,
  91 approach suggested by Tim Mooney.
  92
  93 2.3.94
  94
  95 fc-cat can take directories as input and creates old-style fonts.cache
  96 listings.
  97 fc-cache takes -r --really-force which blows away all old caches and
  98 regenerates.
  99 Robustness fixes, integer overflow fixes (notably to cache handling
 100 code), toast broken global cache files.
 101 Change binary format to make it compatible with static langset
 102 information (thanks to Takashi Iwai).
 103 Open hashed caches before fonts.cache-2 (Takashi Iwai).
 104 Fix FcFontSetMatch's algorithm, which used to unjustly kill fonts for
 105 not declaring certain elements (Takashi Iwai).
 106 Fix matching bug when multiple elements match; don't use
 107 the sum of all scores, but the best score (James Su).
 108 Make fc-lang more friendly to Windows systems.
 109 Remove archaic chars from Georgian charset; add Euro character to
 110 charsets for European languages.
 111 Fix treatment of broken PCF fonts that don't declare family names.
 112 Pass O_BINARY to open if appropriate (reported by Doodle).
 113 Normalize font directories to the form in which they appear in
 114 config files.
 115 Add a record of the cached directory to the cache file.
 116 Perf optimizations (Dirk Mueller; some reported by Michael Meeks.)
 117 Don't loop infinitely on recursive symlinks.
 118 Make 'make distcheck' work with automake 1.6.3.
 119 Replace 'stamp' target with mkinstalldirs.
 120 Don't stop scanning if a directory in fonts.conf doesn't exist,
 121 because subsequent directories might exist.
 122 Put directory names into global cache (reported by Ronny V. Vindenes).
 123 Treat zh-hk fonts differently from zh-tw fonts.  This patch may cause
 124 fontconfig to treat A-X fonts differently from A-Y fonts; please mail
 125 the fontconfig list if this causes any problems.
 126 Fix for unaligned memory accesses (Andreas Schwab).
 127 Fix treatment of cache directory as read from cache file; don't use
 128 string equality to determine if we have the right file, use inode
 129 equality.
 130 Properly skip past dir caches that contain zero fonts, as occurs
 131 in global caches (reported by Mike Fabian).
 132 Print out full pathname in fc-match -v (reported by Frederic Crozat).
 133 Fix bug where fc-match crashes when given __DUMMY__ property to
 134 match on.
 135
 136 2.3.93
 137
 138 Create cache files in /var/cache/fontconfig with hashed filenames, if
 139 possible, for added FHS compliance.
 140 Make fc-cat read both per-directory and global cache files.
 141 Add config file for Persian fonts from Sharif FarsiWeb, Inc.
 142 Major performance improvements by Dirk Mueller, Stephen Kulow, and Michael Matz at SuSE: in particular, speed up FcFontSetMatch, and inline many functions.
 143 Fix treatment of globs in config files, broken since 2.3.2 and discovered by Mathias Clasen.
 144 Don't use freetype internal headers (patch by Matthias Clasen).
 145 Further space improvements: create langsets statically, so that they can live in .rodata.
 146 Properly align mmapped data structures to make e.g. ia64 happy.
 147 Bug fixes.
 148
 149 2.3.92
 150
 151 Fix corrupted caches bugs from 2.3.91 (reported by Mike Fabian).
 152 Store only basename in the cache, reconstitute on demand
 153 (reported by James Cloos).
 154 Change the rule for artificial emboldening in fonts.conf.in.  This
 155 enables the support for artificial emboldening included in cairo
 156 (patch by Zhe Su).
 157 Add FC_EMBEDDED_BITMAP object type to tell Xft/Cairo whether
 158 to load embedded bitmaps or not (patch by Jinghua Luo).
 159 Fix GCC4 warnings (some by Behdad Esfahbod).
 160 Support localized font family and style names; this has been reported
 161 to break old apps like xfd, but modern (gtk+/qt/mozilla) apps work
 162 fine (patch by Zhe Su).
 163 Prevent fc-list from escaping strings when printing them (reported by
 164 Matthias Clasen).
 165 Add valist sentinel markup for FcObjectSetBuild and
 166 FcPatternBuild (patch by Marcus Meissner).
 167 Add consts to variables so as to move arrays into .rodata (patch by
 168 Ross Burton).
 169 Modify config file to use Greek fonts before Asian fonts with
 170 Greek glyphs. (patch by Simos Xenitellis).
 171 Use libtool -no-undefined flag on all platforms (patch by Christian
 172 Biesinger).
 173
 174 2.3.91
 175
 176 Use libxml2 if requested or if expat not available. (Mathias Hasselmann)
 177 Fix multi-arch cache files: compute the position for the
 178 block to be added using info from OrigFile, not NewFile. (plam)
 179 Cast results of sizeof() to unsigned int to get rid of
 180 warnings on x86_64 (reported by Matthias Clasen).
 181 Use FcAtomic to rewrite cache files; don't unlink the fonts.cache-2
 182 file even if there's no data to write; just write an empty cache file.
 183 (Reported by Lubos Lunak)
 184 Allocate room for the subdirectory names in each directory cache.
 185 (Reported by James Cloos)
 186
 187 2.3.90

 210 Fix memory leak of patterns rejected by configuration (#2518)
 211
 212 Create prototype /etc/fonts/conf.d directory and populate it with a few

 248 2.2.97
 249
 250 Fc-cache sleeps before exiting to ensure filesystem timestamps are well
 251 ordered.
 252
 253 Added Punjai orthography.
 254
 255 The timestamp in fonts.conf is gone now.  Too many problems.
 256
 257 The default font path includes all of the X fonts; use selectfont/rejectfont
 258 to eliminate bitmaps, as shown in the sample local.conf file.
 259
 260 <include> configuration elements may now reference a directory.  Files
 261 in that directory matching [0-9]* are loaded in UTF-8 collating sequence order.
 262
 263 <selectfont> configuration added to control which fonts are used.
 264
 265 fontformat font pattern elements built from the FT_Get_X11_Font_Format

 276 Fix FcConfigUpToDate to actually check all font directories and eliminate
 277 a typo which completely prevented it from working (Lubos Lunak
 278 <l.lunak@suse.cz>)
 279
 280 Remove comma at end of FcResult enum definition for picky compilers.
 281
 282 2.2.95
 283
 284 Add FcResultOutOfMemory so FcFontSetMatch can return accurate error.
 285
 286 Replace MIN/MAX/ABS macros which happened to be in old FreeType releases
 287 with FC_MIN/FC_MAX/FC_ABS macros owned by fontconfig.
 288
 289 2.2.94
 290
 291 The 2.2.93 release was prepared with a broken libtool which created
 292 the shared library without the '.so' in the file names.
 293
 294 2.2.93
 295
 296 This is the third prerelease of fontconfig 2.3.  Significant changes from
 297 2.2.92 are:
 298
 299  o      Use new FreeType #include syntax
 300  o      use y_ppem field instead of 'height' in bitmap sizes rec -
 301         FreeType changed the semantics.  Still uses height for
 302         older versions of FreeType
 303  o      Don't construct program manuals unless docbook is available
 304
 305 2.2.92
 306
 307  o      make distcheck work
 308
 309 2.2.91
 310
 311  o      Switch to SGML manuals
 312  o      Add FC_DUAL width spacing value
 313  o      Add FcFini to close out fontconfig and release all memory
 314
 315 2.2
 316
 317 This is the third public release of fontconfig, a font configuration and
 318 customization library.  Fontconfig is designed to locate fonts within the
 319 system and select them according to requirements specified by applications.
 320
 321 Fontconfig is not a rasterization library, nor does it impose a particular
 322 rasterization library on the application.  The X-specific library
 323 'Xft' uses fontconfig along with freetype to specify and rasterize fonts.
