Owen Taylor discovered a rather serious memory usage issue with fcpackage
RC2; it was using about 1MB of memory for language coverage information.
I've had to restructure how the language coverage information was stored,
the result is that language coverage now consumes about 2KB.
However, this was a more significant change to the library than I really
wanted to see at this point, the result is that I've cut another release
candidate and I'd like to get a bit of help in testing to make sure
nothing unexpected has happened.

ChangeLog since RC2:
Mon Aug 26 13:37:23 PDT 2002 keithp
+ Append a version number to cache filenames
Thu Aug 22 11:36:18 PDT 2002 keithp
+ Add "contains" and "not_contains" operators and elements to
font configuration
+ Changed semantics of eq operator for LangSets to check for
FcLangEqual so that any match will do
+ FcFontList was using FcConfigCompareValue (...FcOpEqual) instead
of FcValueEqual to check for identical values when inserting into
the results. This broke when the above semantic change was made,
now it uses FcValueEqual which is "more correct" in any case.
Thu Aug 22 00:32:29 PDT 2002 keithp
+ Reimplement FC_LANG as new datatype. Lists of strings
was consuming over a megabyte of memory for 401 fonts.
+ Freeze patterns loaded from cache files. This shares
common value lists and common patterns which saves
considerable memory.
+ Change the denotation of 'constant' charsets to use special
ref value instead of separate boolean.
+ Clean up leak tracing stuff, found several unannoted alloc/free
calls
Tue Aug 20 16:17:37 PDT 2002 keithp
+ Fix memory leak when parsing matrices from XML
Mon Aug 19 11:57:27 PDT 2002 keithp
+ Fix autoconf files to pass FONTCONFIG_PATH on
compile line so that ${prefix} gets substituted
correctly.
+ Use getc_unlocked/putc_unlocked on systems that
provide them to avoid damage done to stdio by posix
+ Eliminate FC_PATTERN and FcTypePattern in favor of
an extended api for FcConfigSubstitute which takes
both the font and the pattern.
+ Add 'sans serif' alias for 'sans-serif' as some apps
can't handle hyphens in family names
+ Eliminate pretense of support for libxml2
+ Comment origins of Han orthographies
