2007-01-31  Werner Lemberg  <[e-mail]>


	* Version 2.3.1 released.
	=========================


	Tag sources with `VER-2-3-1-FINAL'.

	* builds/win32/visualc/freetype.dsp,
	builds/win32/visualc/freetype.vcproj: s/230/231/.
	* builds/win32/visualc/index.html: s/221/231/.

	* vms_make.com: Add `ftgasp'.

2007-01-30  David Turner  <[e-mail]>

	Tag sources with VER-2-3-1 to prepare release.

	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 1.

	* docs/VERSION.DLL, docs/release, README, Jamfile (RefDoc):
	s/2.3.0/2.3.1/.

	* builds/unix/configure.raw (version_info): Set to 9:12:3.


	* src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
	(af_loader_load_g): Disable the warper (i.e., the light hinting
	improvements) to make a 2.3.1 bugfix release before introducing a
	new feature.  This should give us more time to tune and improve the
	warper for the next release.

	* docs/CHANGES: Update accordingly.

2007-01-25  David Turner  <[e-mail]>

	For light auto-hinting, improve glyph advance widths and resurrect
	normal/full hinting to its normal quality.

	* src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
	and `xmax_delta'.
	* src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
	and `xmax_delta'.

	* src/autofit/afloader.c (af_loader_load_g) <AF_USE_WARPER>: Replace
	preprocessor conditional with if-clause, handling both light and
	normal mode.

	* src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.
	(af_warper_compute): Handle `xmin_delta' and `xmax_delta'.

2007-01-25  Werner Lemberg  <[e-mail]>

	* docs/release: Updated -- Savannah uses a new uploading scheme.

2007-01-25  David Turner  <[e-mail]>

	* src/cff/cffload.c (cff_index_get_pointers): Improve previous fix.

	* src/cff/cffgload.c (cff_decoder_parse_charstrings)
	<cff_op_callsubr, cff_op_callgsubr>: Fix sanity check for empty
	functions.

	* docs/CHANGES: Document light auto-hinting improvement.

2007-01-25  Werner Lemberg  <[e-mail]>

	* src/cff/cffload.c (cff_index_get_pointers): Handle last entry
	correctly in a sanity check.  Since this function is only used to
	load local and global functions, any charstring that called the last
	local/global function would fail otherwise.  This fixes Savannah bug
	#18867.

	* docs/CHANGES: Document it.

2007-01-23  David Turner  <[e-mail]>

	* src/truetype/ttobjs.c (tt_size_ready_bytecode): Fix typo that
	prevented compilation when disabling both the unpatented and the
	bytecode interpreter in the TrueType font driver.


	Fix and enable the warper to improve `light' hinting mode.  This is
	not necessarily a final version, but it seems to work well.

	* src/autofit/aflatin.c (af_latin_hints_init) [AF_USE_WARPER]:
	Disable code.
	(af_latin_hints_apply) [AF_USE_WARPER]: Handle FT_RENDER_MODE_LIGHT.
	* src/autofit/aftypes.h: Activate AF_USE_WARPER.

	* src/autofit/afwarp.c (AF_WarpScore): Tune table.
	(af_warper_compute_line_best): Fix array size of `scores'.
	(af_warper_compute): Better handling of border cases.
	* src/autofit/afwarp.h (AF_WarperRec): Remove unused members `X1'
	and `X2'.

2007-01-21  Werner Lemberg  <[e-mail]>

	* docs/CHANGES: Document SHZ fix.

	points.

2007-01-21  Werner Lemberg  <[e-mail]>

	* src/sfnt/ttmtx.c (tt_face_get_metrics)
	[!FT_CONFIG_OPTION_OLD_INTERNALS]: Fix limit check.

	* builds/amiga/include/freetype/config/ftconfig.h: Synchronize.

2007-01-14  Detlef Würkner  <[e-mail]>

	Fix various compiler warnings.

	* src/truetype/ttdriver.c (tt_size_select), src/cff/cffobjs.h,

	s/index/strike_index/.
	* src/base/ftobjs.c (FT_Match_Size): s/index/size_index/.

	* src/gxvalid/gxvmorx5.c

	(cff_service_ps_info): Register cff_ps_get_font_info.

2007-01-13  Werner Lemberg  <[e-mail]>

	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Fix compilation
	with C++ compiler.

	* src/autofit/afhints.c (af_glyph_hints_dump_segments,
	af_glyph_hints_dump_edges): Ditto.

	crash with some Mac OS X .dfont files.  Submitted by Masatake
	Yamato.

	* autogen.sh: Small fix to get it working on Mac OS X properly:
	The issue is that GNU libtool is called `glibtool' on this platform,
