 240 2.3.95
 241
 242 Match 'Standard Symbols L' for 'Symbol'.  Add URW fonts as aliases for
 243 all of the PostScript fonts.  (reported by Miguel Rodriguez).  Fix a
 244 number of Coverity defects (Frederic Crozat).  Speed up FcFontSort
 245 (fix suggested by Kenichi Handa).  Fix error with charsets.  Survive
 246 missing docbook2pdf.  Compile on HP-UX, AIX, SGI and Windows (Cygwin,
 247 MinGW).  Fix intel compiler warnings.  Fix multiarch support (don't
 248 destroy multiarch files!)  Require pkg-config.  (Thanks Behdad; better
 249 solution wanted for libxml2 detection!)  Fix typos in orth files and
 250 add orth for Lingala (reported by Denis Jacquerye).  Remove debian/
 251 directory.  Add a configuration file that disables hinting for the
 252 Lohit Gujarati font (since the hinting distorts some glyphs quite
 253 badly).  Sort directory entries while scanning them from disk;
 254 prevents Heisenbugs due to file ordering in a directory (due to Egmont
 255 Koblinger).  Fix Wine's problem with finding fonts.  (Reported by
 256 Bernhard Rosenkraenzer.)  Fix the issues with GNU libiconv vs. libc
 257 iconv (which especially appear on Solarii); patch by Behdad Esfahbod,
 258 approach suggested by Tim Mooney.
 259
 260 2.3.94
 261
 262 fc-cat can take directories as input and creates old-style fonts.cache
 263 listings.
 264 fc-cache takes -r --really-force which blows away all old caches and
 265 regenerates.
 266 Robustness fixes, integer overflow fixes (notably to cache handling
 267 code), toast broken global cache files.
 268 Change binary format to make it compatible with static langset
 269 information (thanks to Takashi Iwai).
 270 Open hashed caches before fonts.cache-2 (Takashi Iwai).
 271 Fix FcFontSetMatch's algorithm, which used to unjustly kill fonts for
 272 not declaring certain elements (Takashi Iwai).
 273 Fix matching bug when multiple elements match; don't use
 274 the sum of all scores, but the best score (James Su).
 275 Make fc-lang more friendly to Windows systems.
 276 Remove archaic chars from Georgian charset; add Euro character to
 277 charsets for European languages.
 278 Fix treatment of broken PCF fonts that don't declare family names.
 279 Pass O_BINARY to open if appropriate (reported by Doodle).
 280 Normalize font directories to the form in which they appear in
 281 config files.
 282 Add a record of the cached directory to the cache file.
 283 Perf optimizations (Dirk Mueller; some reported by Michael Meeks.)
 284 Don't loop infinitely on recursive symlinks.
 285 Make 'make distcheck' work with automake 1.6.3.
 286 Replace 'stamp' target with mkinstalldirs.
 287 Don't stop scanning if a directory in fonts.conf doesn't exist,
 288 because subsequent directories might exist.
 289 Put directory names into global cache (reported by Ronny V. Vindenes).
 290 Treat zh-hk fonts differently from zh-tw fonts.  This patch may cause
 291 fontconfig to treat A-X fonts differently from A-Y fonts; please mail
 292 the fontconfig list if this causes any problems.
 293 Fix for unaligned memory accesses (Andreas Schwab).
 294 Fix treatment of cache directory as read from cache file; don't use
 295 string equality to determine if we have the right file, use inode
 296 equality.
 297 Properly skip past dir caches that contain zero fonts, as occurs
 298 in global caches (reported by Mike Fabian).
 299 Print out full pathname in fc-match -v (reported by Frederic Crozat).
 300 Fix bug where fc-match crashes when given __DUMMY__ property to
 301 match on.
 302
 303 2.3.93
 304
 305 Create cache files in /var/cache/fontconfig with hashed filenames, if
 306 possible, for added FHS compliance.
 307 Make fc-cat read both per-directory and global cache files.
 308 Add config file for Persian fonts from Sharif FarsiWeb, Inc.
 309 Major performance improvements by Dirk Mueller, Stephen Kulow, and Michael Matz at SuSE: in particular, speed up FcFontSetMatch, and inline many functions.
 310 Fix treatment of globs in config files, broken since 2.3.2 and discovered by Mathias Clasen.
 311 Don't use freetype internal headers (patch by Matthias Clasen).
 312 Further space improvements: create langsets statically, so that they can live in .rodata.
 313 Properly align mmapped data structures to make e.g. ia64 happy.
 314 Bug fixes.
 315
 316 2.3.92
 317

 319 Store only basename in the cache, reconstitute on demand
 320 (reported by James Cloos).

 322 enables the support for artificial emboldening included in cairo
 323 (patch by Zhe Su).
 324 Add FC_EMBEDDED_BITMAP object type to tell Xft/Cairo whether
 325 to load embedded bitmaps or not (patch by Jinghua Luo).
 326 Fix GCC4 warnings (some by Behdad Esfahbod).
 327 Support localized font family and style names; this has been reported
 328 to break old apps like xfd, but modern (gtk+/qt/mozilla) apps work
 329 fine (patch by Zhe Su).

 331 Matthias Clasen).
 332 Add valist sentinel markup for FcObjectSetBuild and
 333 FcPatternBuild (patch by Marcus Meissner).

 338 Use libtool -no-undefined flag on all platforms (patch by Christian
 339 Biesinger).
 340
 341 2.3.91
 342
 343 Use libxml2 if requested or if expat not available. (Mathias Hasselmann)
 344 Fix multi-arch cache files: compute the position for the
 345 block to be added using info from OrigFile, not NewFile. (plam)
 346 Cast results of sizeof() to unsigned int to get rid of
 347 warnings on x86_64 (reported by Matthias Clasen).
 348 Use FcAtomic to rewrite cache files; don't unlink the fonts.cache-2
 349 file even if there's no data to write; just write an empty cache file.

 420 Added Punjai orthography.
 421
 422 The timestamp in fonts.conf is gone now.  Too many problems.
 423
 424 The default font path includes all of the X fonts; use selectfont/rejectfont
 425 to eliminate bitmaps, as shown in the sample local.conf file.
 426
 427 <include> configuration elements may now reference a directory.  Files
 428 in that directory matching [0-9]* are loaded in UTF-8 collating sequence order.

 442
 443 Fix FcConfigUpToDate to actually check all font directories and eliminate

 445 <l.lunak@suse.cz>)
 446
 447 Remove comma at end of FcResult enum definition for picky compilers.
 448

 455
 456 2.2.94
 457
 458 The 2.2.93 release was prepared with a broken libtool which created
 459 the shared library without the '.so' in the file names.
 460
 461 2.2.93
 462
 463 This is the third prerelease of fontconfig 2.3.  Significant changes from
 464 2.2.92 are:
 465
 466  o      Use new FreeType #include syntax
 467  o      use y_ppem field instead of 'height' in bitmap sizes rec -
 468         FreeType changed the semantics.  Still uses height for
 469         older versions of FreeType
 470  o      Don't construct program manuals unless docbook is available
 471
 472 2.2.92
 473
 474  o      make distcheck work
 475
 476 2.2.91
 477
 478  o      Switch to SGML manuals
 479  o      Add FC_DUAL width spacing value
 480  o      Add FcFini to close out fontconfig and release all memory
 481
 482 2.2
 483
 484 This is the third public release of fontconfig, a font configuration and
 485 customization library.  Fontconfig is designed to locate fonts within the
 486 system and select them according to requirements specified by applications.
 487
 488 Fontconfig is not a rasterization library, nor does it impose a particular
 489 rasterization library on the application.  The X-specific library
 490 'Xft' uses fontconfig along with freetype to specify and rasterize fonts.
