Adding the FT_Face_CheckTrueTypePatents API to FT_FREETYPE_H, it is
implemented by the optional src/base/ftpatent.c
builds/win32/visualc/freetype.vcproj, docs/VERSION.DLL,
include/freetype/freetype.h, include/freetype/t1tables.h,
include/freetype/internal/tttypes.h: updating version
number to 2.3.0 !!
* include/freetype/ftchapters.h, include/freetype/ftgasp.h,
include/freetype/ftlcdfil.h: updating reference documentation
with GASP support and LCD filtering sections
src/base/ftlcdfilt.c, src/smooth/ftsmooth.c: API change for
the LCD filter, the FT_LcdFilter value is a enum describing
which filter to apply, new values FT_LCD_FILTER_LIGHT and
FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
algorithm which produces incredible color fringes for everything
except very-well hinted text)
* src/autofit/aflatin.c: various tiny improvements that drastically
improve the handling of serif fonts and of LCD/LCD_V hinting modes.
* include/freetype/config/ftstdlib.h: Cast away volatileness from
argument to ft_setjmp.
* include/freetype/internal/ftvalid.h: Add comment that
ft_validator_run must not be used.
src/base/ftobjs.c: fixed a bug in the automatic unpatented
hinting support which prevented normal bytecode hinting to
work properly
* src/autofit/aftypes.h: undefining AF_DEBUG to get rid of
traces
for an upcoming 2.2.2 release
* include/freetype/ftlcdfil.h, src/freetype/ftlcdfil.c:
added a new API to support color filtering of subpixel glyph
bitmaps. In default build, the function FT_Library_SetLcdFilter
returns FT_Err_Unimplemented_Feature; you need to #define
FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile
the real implementation
* src/smooth/ftsmooth.c: adding support for sub-pixel color
filtering; simplifying a few function calls
* include/freetype/config/ftheader.h: adding FT_LCD_FILTER_H
macro that points to <freetype/ftlcdfil.h>
Fix miscellaneous compiler warnings.
* freetype2/include/freetype/internal/ftobjs.h: close
comment with `*/' to avoid `/* in comment' compiler warning.
* freetype2/src/base/ftdbgmem.c (ft_mem_table_get_source): Turn
cast `(FT_UInt32)(void*)' into `(FT_UInt32)(FT_PtrDist)(void*)'
since on 64-bit platforms void* is larger than FT_UInt32.
* freetype2/src/base/ftobjs.c (t_validator_error): cast
away volatileness of argument to ft_longjmp. Spotted by
Werner `Putzfrau' Lemberg.
* freetype2/src/bdf/bdflib.c (bdf_load_font): initialize
local variable `lineno'.
* freetype2/src/gxvalid/gxvmod.c (classic_kern_validate):
mark local variable `error' volatile.
Fix for previous commit, which caused many compiler warnings/errors
about addresses of volatile objects passed as function arguments
as non-volatile pointers.
* freetype2/include/freetype/internal/ftvalid.h: Make
FT_Validator typedef a pointer to a volatile object.
* freetype2/src/gxvalid/gxvmod.c (gxv_load_table): Make function
argument `table' a pointer to a volatile object.
* freetype2/src/otvalid/otvmod.c (otv_load_table): Make function
argument `table' a pointer to a volatile object.

src/psaux/t1cmap.c, src/psnames/psmodule.c: Fix for the memory
leak described in bug #16759.
We change 'ps_unicodes_init' so that it also takes a 'free_glyph_name'
callback to release the glyph names returned by 'get_glyph_name'
src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c,
src/autofit/aftypes.h, src/base/ftcalc.c, src/base/ftoutln.c,
src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c,
src/type1/t1gload.c:
this is a major patch used to drastically improve the performance
of loading glyphs. This both speeds up loading the glypn vector
themselves and the auto-fitter.
note that we've started using inline assembler with GCC to
implement FT_MulFix, given that this function is so damn
important for the engine's performance.
the resulting speed-up is about 25%.
* include/freetype/*: s/scale/scaling value/ where appropriate.
Many other minor documentation improvements.
* src/tools/docmaker/sources.py (re_italic, re_bold): Handle
trailing punctuation.
* src/tools/docmaker/tohtml.py (HtmlFormatter::make_html_word): Add
warning message for undefined cross references.
Update handling of re_italic and re_bold.
