	version number to 2.3.4.

	* README, Jamfile (RefDoc), builds/win32/visualc/index.html,
	builds/win32/visualc/freetype.dsp,
	builds/win32/visualc/freetype.vcproj: s/2.3.3/2.3.4/, s/233/234/.

	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 4.

	* builds/unix/configure.raw (version_info): Set to 9:15:3.

2007-04-09  Martin Horak  <[e-mail]>

	* src/truetype/ttgload.c (load_truetype_glyph): Save and restore
	memory stream to avoid a crash with the incremental memory
	interface (Savannah bug #19260).

2007-04-06  David Turner  <[e-mail]>

	* src/base/ftbimap.c (ft_bitmap_assure_buffer): Fix buffer-overwrite bug
	(Savannah bug #19536).

2007-04-04  Werner Lemberg  <[e-mail]>

	* Version 2.3.3 released.
	=========================


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

	* docs/CHANGES: Mention CVE-2007-1351.

2007-04-03  David Turner  <[e-mail]>

	* src/base/ftobjs.c (FT_Set_Char_Size): As suggested by James Cloos,
	if one of the resolution values is 0, treat it as if it were the
	same as the other value.

2007-04-02  David Turner  <[e-mail]>

	Add special code to detect `extra-light' fonts and do not snap their
	stem widths too much to avoid bizarre hinting effects.

	* src/autofit/aflatin.h (AF_LatinAxisRec): Add `standard_width' and
	`extra_light' members.

	* src/autofit/aflatin.c (af_latin_metrics_init_widths): Initialize
	them.
	(af_latin_metrics_scale_dim): Set `extra_light'.
	(af_latin_compute_stem_width): Use `extra_light'.

2007-03-28  David Turner  <[e-mail]>

	* src/base/ftbitmap.c (ft_bitmap_assure_buffer): Fix zero-ing of the
	padding.

2007-03-28  Werner Lemberg  <[e-mail]>

	* src/bdf/bdflib.c (setsbit, sbitset): Handle values >= 128
	gracefully.
	(_bdf_set_default_spacing): Increase `name' buffer size to 256 and
	issue an error for longer names.  This fixes CVE-2007-1351.
	(_bdf_parse_glyphs): Limit allowed number of glyphs in font to the
	number of code points in Unicode.

	* builds/win32/visualc/index.html,
	builds/win32/visualc/freetype.dsp,
	builds/win32/visualc/freetype.vcproj, README: s/2.3.2/2.3.3/,
	s/232/233/.

2007-03-26  David Turner  <[e-mail]>

	* src/truetype/ttinterp.c [FIX_BYTECODE]: Remove it and
	corresponding code.
	(Ins_MD): Last regression fix.

	* src/autofit/aflatin.c (af_latin_metrics_init_blues): Fix blues
	computations in order to ignore single-point contours.  These are
	never rasterized and correspond in certain fonts to mark-attach
	points that are very far from the glyph's real outline, ruining the
	computation.

	* src/autofit/afloader.c (af_loader_load_g): In the case of
	monospaced fonts, always set `rsb_delta' and `lsb_delta' to 0. 
	Otherwise code that uses them will most certainly ruin the fixed
	advance property.

	* docs/CHANGES, docs/VERSION.DLL, README, Jamfile (RefDoc): Update
	documentation and bump version number to 2.3.3.

	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 3.

2007-03-22  suzuki toshiya  <[e-mail]>

	* builds/unix/ftsystem.c (FT_Stream_Open): Temporary fix to prevent
	32bit unsigned long overflow by 64bit filesize on LP64 platform, as
	proposed by Sean McBride:
	http://lists.gnu.org/archive/html/freetype-devel/2007-03/msg00032.html

2007-03-22  suzuki toshiya  <[e-mail]>

	setjmp, proposed by Sean McBride:
	http://lists.gnu.org/archive/html/freetype-devel/2007-03/msg00032.html

2007-03-19  suzuki toshiya  <[e-mail]>

	* builds/unix/configure.raw: Dequote `OS_INLINE' in comment of
	conftest.c, to avoid unexpected shell evaluation.  Possibly it is a
	bug or undocumented behaviour of autoconf.

2007-03-18  David Turner   <[e-mail]>

	* src/truetype/ttinterp.c (Ins_MDRP): Another bytecode regression
	fix; testing still needed.

	<[e-mail]>.

	* src/type1/t1afm.c (T1_Read_PFM): Read kerning values as 16-bit
	signed values, not unsigned ones.  Problem reported by Johannes
	Walther <[e-mail]>.
