 110 2.3.95
 111
 112 Match 'Standard Symbols L' for 'Symbol'.  Add URW fonts as aliases for
 113 all of the PostScript fonts.  (reported by Miguel Rodriguez).  Fix a
 114 number of Coverity defects (Frederic Crozat).  Speed up FcFontSort
 115 (fix suggested by Kenichi Handa).  Fix error with charsets.  Survive
 116 missing docbook2pdf.  Compile on HP-UX, AIX, SGI and Windows (Cygwin,
 117 MinGW).  Fix intel compiler warnings.  Fix multiarch support (don't
 118 destroy multiarch files!)  Require pkg-config.  (Thanks Behdad; better
 119 solution wanted for libxml2 detection!)  Fix typos in orth files and
 120 add orth for Lingala (reported by Denis Jacquerye).  Remove debian/
 121 directory.  Add a configuration file that disables hinting for the
 122 Lohit Gujarati font (since the hinting distorts some glyphs quite
 123 badly).  Sort directory entries while scanning them from disk;
 124 prevents Heisenbugs due to file ordering in a directory (due to Egmont
 125 Koblinger).  Fix Wine's problem with finding fonts.  (Reported by
 126 Bernhard Rosenkraenzer.)  Fix the issues with GNU libiconv vs. libc
 127 iconv (which especially appear on Solarii); patch by Behdad Esfahbod,
 128 approach suggested by Tim Mooney.
 129
 130 2.3.94
 131
 132 fc-cat can take directories as input and creates old-style fonts.cache
 133 listings.
 134 fc-cache takes -r --really-force which blows away all old caches and
 135 regenerates.
 136 Robustness fixes, integer overflow fixes (notably to cache handling
 137 code), toast broken global cache files.
 138 Change binary format to make it compatible with static langset
 139 information (thanks to Takashi Iwai).
 140 Open hashed caches before fonts.cache-2 (Takashi Iwai).
 141 Fix FcFontSetMatch's algorithm, which used to unjustly kill fonts for
 142 not declaring certain elements (Takashi Iwai).
 143 Fix matching bug when multiple elements match; don't use
 144 the sum of all scores, but the best score (James Su).
 145 Make fc-lang more friendly to Windows systems.
 146 Remove archaic chars from Georgian charset; add Euro character to
 147 charsets for European languages.
 148 Fix treatment of broken PCF fonts that don't declare family names.
 149 Pass O_BINARY to open if appropriate (reported by Doodle).
 150 Normalize font directories to the form in which they appear in
 151 config files.
 152 Add a record of the cached directory to the cache file.
 153 Perf optimizations (Dirk Mueller; some reported by Michael Meeks.)
 154 Don't loop infinitely on recursive symlinks.
 155 Make 'make distcheck' work with automake 1.6.3.
 156 Replace 'stamp' target with mkinstalldirs.
 157 Don't stop scanning if a directory in fonts.conf doesn't exist,
 158 because subsequent directories might exist.
 159 Put directory names into global cache (reported by Ronny V. Vindenes).
 160 Treat zh-hk fonts differently from zh-tw fonts.  This patch may cause
 161 fontconfig to treat A-X fonts differently from A-Y fonts; please mail
 162 the fontconfig list if this causes any problems.
 163 Fix for unaligned memory accesses (Andreas Schwab).
 164 Fix treatment of cache directory as read from cache file; don't use
 165 string equality to determine if we have the right file, use inode
 166 equality.
 167 Properly skip past dir caches that contain zero fonts, as occurs
 168 in global caches (reported by Mike Fabian).
 169 Print out full pathname in fc-match -v (reported by Frederic Crozat).
 170 Fix bug where fc-match crashes when given __DUMMY__ property to
 171 match on.
 172
 173 2.3.93
 174
 175 Create cache files in /var/cache/fontconfig with hashed filenames, if
 176 possible, for added FHS compliance.
 177 Make fc-cat read both per-directory and global cache files.
 178 Add config file for Persian fonts from Sharif FarsiWeb, Inc.
 179 Major performance improvements by Dirk Mueller, Stephen Kulow, and Michael Matz at SuSE: in particular, speed up FcFontSetMatch, and inline many functions.
 180 Fix treatment of globs in config files, broken since 2.3.2 and discovered by Mathias Clasen.
 181 Don't use freetype internal headers (patch by Matthias Clasen).
 182 Further space improvements: create langsets statically, so that they can live in .rodata.
 183 Properly align mmapped data structures to make e.g. ia64 happy.
 184 Bug fixes.
 185
 186 2.3.92
 187
 188 Fix corrupted caches bugs from 2.3.91 (reported by Mike Fabian).
 189 Store only basename in the cache, reconstitute on demand
 190 (reported by James Cloos).
 191 Change the rule for artificial emboldening in fonts.conf.in.  This
 192 enables the support for artificial emboldening included in cairo
 193 (patch by Zhe Su).
 194 Add FC_EMBEDDED_BITMAP object type to tell Xft/Cairo whether
 195 to load embedded bitmaps or not (patch by Jinghua Luo).
 196 Fix GCC4 warnings (some by Behdad Esfahbod).
 197 Support localized font family and style names; this has been reported
 198 to break old apps like xfd, but modern (gtk+/qt/mozilla) apps work
 199 fine (patch by Zhe Su).
 200 Prevent fc-list from escaping strings when printing them (reported by
 201 Matthias Clasen).
 202 Add valist sentinel markup for FcObjectSetBuild and
 203 FcPatternBuild (patch by Marcus Meissner).
 204 Add consts to variables so as to move arrays into .rodata (patch by
 205 Ross Burton).
 206 Modify config file to use Greek fonts before Asian fonts with
 207 Greek glyphs. (patch by Simos Xenitellis).
 208 Use libtool -no-undefined flag on all platforms (patch by Christian
 209 Biesinger).
 210
 211 2.3.91
 212
 213 Use libxml2 if requested or if expat not available. (Mathias Hasselmann)
 214 Fix multi-arch cache files: compute the position for the
 215 block to be added using info from OrigFile, not NewFile. (plam)
 216 Cast results of sizeof() to unsigned int to get rid of
 217 warnings on x86_64 (reported by Matthias Clasen).
 218 Use FcAtomic to rewrite cache files; don't unlink the fonts.cache-2
 219 file even if there's no data to write; just write an empty cache file.
 220 (Reported by Lubos Lunak)
 221 Allocate room for the subdirectory names in each directory cache.
 222 (Reported by James Cloos)
 223
 224 2.3.90

 284
 285 2.2.97
 286
 287 Fc-cache sleeps before exiting to ensure filesystem timestamps are well
 288 ordered.
 289
 290 Added Punjai orthography.
 291
 292 The timestamp in fonts.conf is gone now.  Too many problems.
 293
 294 The default font path includes all of the X fonts; use selectfont/rejectfont
 295 to eliminate bitmaps, as shown in the sample local.conf file.
 296
 297 <include> configuration elements may now reference a directory.  Files
 298 in that directory matching [0-9]* are loaded in UTF-8 collating sequence order.
 299
 300 <selectfont> configuration added to control which fonts are used.
 301
 302 fontformat font pattern elements built from the FT_Get_X11_Font_Format

 309 parallel <foo>lang properties marking language.
 310
 311 2.2.96
 312
 313 Fix FcConfigUpToDate to actually check all font directories and eliminate
 314 a typo which completely prevented it from working (Lubos Lunak
 315 <l.lunak@suse.cz>)
 316
 317 Remove comma at end of FcResult enum definition for picky compilers.
 318
 319 2.2.95
 320
 321 Add FcResultOutOfMemory so FcFontSetMatch can return accurate error.
 322
 323 Replace MIN/MAX/ABS macros which happened to be in old FreeType releases
 324 with FC_MIN/FC_MAX/FC_ABS macros owned by fontconfig.
 325
 326 2.2.94
 327
 328 The 2.2.93 release was prepared with a broken libtool which created
 329 the shared library without the '.so' in the file names.
 330
 331 2.2.93
 332
 333 This is the third prerelease of fontconfig 2.3.  Significant changes from
 334 2.2.92 are:
 335
 336  o      Use new FreeType #include syntax
 337  o      use y_ppem field instead of 'height' in bitmap sizes rec -
 338         FreeType changed the semantics.  Still uses height for
 339         older versions of FreeType
 340  o      Don't construct program manuals unless docbook is available
 341
 342 2.2.92
 343
 344  o      make distcheck work
 345
 346 2.2.91
 347
 348  o      Switch to SGML manuals
 349  o      Add FC_DUAL width spacing value
 350  o      Add FcFini to close out fontconfig and release all memory
 351
 352 2.2
 353
 354 This is the third public release of fontconfig, a font configuration and
 355 customization library.  Fontconfig is designed to locate fonts within the
 356 system and select them according to requirements specified by applications.
 357
 358 Fontconfig is not a rasterization library, nor does it impose a particular
 359 rasterization library on the application.  The X-specific library
 360 'Xft' uses fontconfig along with freetype to specify and rasterize fonts.
