	* README: Fix typo.
	* docs/CHANGES: Minor fixes.


	* Version 2.0.8 released.
	=========================


2002-02-08  David Turner  <[e-mail]>

	* docs/CHANGES: Updating for 2.0.8.

	* include/freetype/freetype.h: Setting `PATCH_LEVEL' to 8 and
	removing `FT_Get_Next_Char' from the API (temporarily).

	* include/freetype/freetype.h: Adding comments to FT_Get_Next_Char;
	note that this function might temporarily be removed for the 2.0.8
	release.

2002-02-07  David Turner  <[e-mail]>

	* src/pcf/pcfread.c (pcf_load_font): Removed immature support of
	the AVERAGE_WIDTH property.

2002-02-06  David Turner  <[e-mail]>

	* src/sfnt/sfobjs.c (SFNT_Load_Face): Since many fonts embedded in
	PDF documents do not include 'cmap', 'post' and 'name' tables, the
	SFNT face loader has been changed to not immediately report an
	error if these are not present.

	Note that the specification _requires_ these tables, but Adobe
	seems to ignore it completely.

	* src/sfnt/ttcmap.c: Removing compiler warnings.

	* src/pcf/pcfread.c (pcf_read_TOC): Use FT_UInt.
	(pcf_parse_metric, pcf_parse_compressed_metric): Removed.  Code
	is now in ...
	(pcf_get_metric): Here.
	(pcfSeekToType): Renamed to ...
	(pcf_seek_to_table_type): This.
	Use FT_Int.
	(pcfHasType): Renamed to ...
	(pcf_has_table_type): This.
	Use FT_Int.
	(find_property): Renamed to ...
	(pcf_find_property): This.
	Use FT_Int.
	(pcf_get_bitmaps, pcf_get_encodings): Handle invalid PCF fonts
	better (delaying format checks out of FT_Access_Frame ..
	FT_Forget_Frame blocks to avoid leaving the stream in an incorrect
	state when encountering an invalid PCF font).

	* src/pcf/pcfdriver.c (PCF_Done_Face): Renamed to ...
	(PCF_Face_Done): This.
	(PCF_Init_Face): Renamed to ...
	(PCF_Face_Init): This.
	(PCF_Get_Char_Index): Renamed to ...
	(PCF_Char_Get_Index): This.
	(PCF_Get_Next_Char): Renamed to ...
	(PCF_Char_Get_Next): This.
	(pcf_driver_class): Updated.

	* src/pcf/pcf.h (PCF_Done_Face): Removed.

2002-02-06  Detlef Würkner  <[e-mail]>

	* src/pcf/pcfdriver.c (FT_Done_Face): Fixed small memory leak.

	* src/pcf/pcfread.c (pcf_load_font): Now handles the `AVERAGE_WIDTH'
	property to return correct character pixel (width/height) pairs for
	embedded bitmaps.

2002-02-04  Keith Packard  <[e-mail]>

	Adding the function `FT_Get_Next_Char', doing the obvious thing
	w.r.t. the selected charmap.

	* include/freetype/freetype.h: Add prototype.
	* include/freetype/internal/ftdriver.h: Add `FTDriver_getNextChar'

	* include/freetype/internal/tttypes.h: Add `TT_CharNext_Func'
	typedef.
	(TT_CMapTable): Use it.

	* src/base/ftobjs.c (FT_Get_Next_Char): New function, implementing
	high-level API.
	* src/cff/cffdrivr.c (cff_get_next_char): New function.
	(cff_driver_class): Add it.
	* src/cid/cidriver.c (Cid_Get_Next_Char): New function.
	(t1cid_driver_class): Add it.

	functions.
	(TT_CharMap_Load): Use them.
	* src/truetype/ttdriver.c (Get_Next_Char): New function.
	(tt_driver_class): Add it.
	* src/type1/t1driver.c (Get_Next_Char): New function.
	(t1_driver_class): Add it.
	* src/winfonts/winfnt.c (FNT_Get_Next_Char): New function.

2002-02-02  Keith Packard  <[e-mail]>

	* builds/unix/freetype-config.in: Add missing `fi'.


	* Version 2.0.7 released.
	=========================


2002-02-01  David Turner  <[e-mail]>

	* include/freetype/freetype.h: Increasing FREETYPE_PATCH to 7
	for the new release.

2002-01-31  David Turner  <[e-mail]>

	* README, README.UNX, docs/CHANGES: Updating documentation for the
	2.0.7 release.

2002-01-30  David Turner  <[e-mail]>

	* INSTALL: Moved to ...
	* docs/INSTALL: Here to avoid conflicts with the `install' script on
	Windows, where the filesystem doesn't preserve case.

2002-01-29  David Turner  <[e-mail]>

	* configure: Fixed the script.  It previously didn't accept more
	than one argument correctly.  For example, when typing:

	  ./configure --disable-shared --disable-nls

	the `--disable-nls' was incorrectly sent to the `make' program.

2002-01-29  Werner Lemberg  <[e-mail]>

	* README.UNX: Fix typo.
	* builds/unix/install.mk (uninstall): Fix library name for libtool.

2002-01-28  Francesco Zappa Nardelli  <[e-mail]>

	* src/pcf/pcfdriver.c (PCF_Done_Face): Fix incorrect destruction of
	the face object (face->toc.tables, face->root.family_name,
	face->root.available_size, face->charset_encoding,
	face->charset_registry are now freed).  Thanks to Niels Moseley.

2002-01-28  Roberto Alameda  <[e-mail]>

	* src/type1/t1load.c (parse_encoding): Set `loader->num_chars'.

2002-01-28  Werner Lemberg  <[e-mail]>

	* src/type1/t1load.c (parse_subrs, parse_charstrings): Use copy
	of `base' string for decrypting to not modify the original data.
	Based on a patch by Jakub Bogusz <[e-mail]>.

2002-01-27  Giuliano Pochini  <[e-mail]>

	* src/smooth/ftgrays.c (gray_render_scanline): Fix bug which caused
	bad rendering of thin lines (less than one pixel thick).

2002-01-25  Werner Lemberg  <[e-mail]>

	* src/cff/cffdrivr.c (cff_get_name_index): Make last patch work
	actually.

2002-01-13  Werner Lemberg  <[e-mail]>

	* builds/unix/freetype2.a4: The script was still buggy.
	* builds/unix/freetype-config.in: Make it really work for any install
	prefix.

2002-01-10  Werner Lemberg  <[e-mail]>

	* builds/unix/freetype2.a4: Fix some serious bugs.

2002-01-09  David Turner  <[e-mail]>

2002-01-09  Maxim Shemanarev  <[e-mail]>

	* src/smooth/ftgrays.c (gray_render_line): Small optimization to
	the smooth anti-aliased renderer that deals with vertical segments.
	This results in a 5-7% speedup in rendering speed.

2002-01-08  David Turner  <[e-mail]>

	Added some wrapper scripts to make the installation more
	Unix-friendly.

	* configure, install: New files.

	* INSTALL, README.UNX: Updated installation documentation to use the

2002-01-07  David Turner  <[e-mail]>


	* Version 2.0.6 released.
	=========================


	* docs/BUGS, docs/CHANGES: Updating documentation for 2.0.6 release.

	* src/tools/docmaker.py: Fixed HTML quoting in sources.
	(html_format): Replaced with ...
	(html_quote): New function.
	(html_quote0): New function.
	(DocCode::dump_html): Small improvement.
	(DocParagraph::dump, DocBlock::html): Use html_quote0 and html_quote.

	* include/freetype/config/ftoption.h: Setting default options for
	a release build (debugging off, bytecode interpreter off).

	* src/base/ftobjs.c, src/base/ftoutln.c, src/cache/ftccmap.c,
	src/cff/cffload.c, src/cff/cffobjs.c, src/pshinter/pshalgo2.c,
	src/sfnt/ttload.c, src/sfnt/ttsbit.c: Removing small compiler
	warnings (in pedantic compilation modes).

2002-01-05  David Turner  <[e-mail]>

	* src/autohint/ahhint.c (ah_align_linked_edge): Modified computation
	of auto-hinted stem widths; this avoids color fringes in
	`ClearType-like' rendering.

	* src/truetype/ttgload.c (TT_Load_Glyph_Header,
	TT_Load_Simple_Glyph, TT_Load_Composite_Glyph, load_truetype_glyph):
	Modified the TrueType loader to make it more paranoid; this avoids
	nasty buffer overflows in the case of invalid glyph data (as
	encountered in the output of some buggy font converters).

2002-01-04  David Turner  <[e-mail]>

	* README.UNX: Added special README file for Unix users.

	* builds/unix/ftsystem.c (FT_New_Stream): Fixed typo.

	* src/base/ftobjs.c: Added #include FT_OUTLINE_H to get rid
	of compiler warnings.

	* src/base/ftoutln.c (FT_Outline_Check): Remove compiler warning.

2002-01-03  Werner Lemberg  <[e-mail]>

	* src/type1/t1objs.c (T1_Face_Init): Add cast to avoid compiler
	warning.

2002-01-03  Keith Packard  <[e-mail]>

	* builds/unix/ftsystem.c (FT_New_Stream): Added a fix to ensure that
	all FreeType input streams are closed in child processes of a `fork'
	on Unix systems.  This is important to avoid (potential) access
	control issues.

2002-01-03  David Turner  <[e-mail]>

	* src/type1/t1objs.c (T1_Face_Init): Fixed a bug that crashed the
	library when dealing with certain weird fonts like `Stalingrad', in
	`sadn.pfb' (this font has no full font name entry).

	* src/base/ftoutln.c, include/freetype/ftoutln.h (FT_Outline_Check):
	New function to check the consistency of outline data.

	* src/base/ftobjs.c (FT_Load_Glyph): Use `FT_Outline_Check' to
	ensure that loaded glyphs are valid.  This allows certain fonts like
	`tt1095m_.ttf' to be loaded even though it appears they contain
	really funky glyphs.

	There still is a bug there, though.

	* src/truetype/ttgload.c (load_truetype_glyph): Fix error condition.

2001-12-30  David Turner  <[e-mail]>

	* src/autohint/ahhint.c (ah_hinter_load): Fix advance width
	computation of auto-hinted glyphs.  This noticeably improves the
	spacing of letters in KDE and Gnome.

2001-12-25  Antoine Leca  <[e-mail]>

	* builds/dos/detect.mk: Correcting the order for Borland compilers:
	16-bit bcc was never selected, always overridden by 32-bit bcc32.

2001-12-22  Francesco Zappa Nardelli  <[e-mail]>

	* src/pfc/pcfread.c (pcf_load_font): Handle property `POINT_SIZE'
	and fix incorrect computation of `available_sizes'.

2001-12-22  David Turner  <[e-mail]>

	* src/autohint/ahhint.c (ah_hinter_load): Auto-hinted glyphs had an
	incorrect glyph advance in the case of mono-width fonts (like
	Courier, Andale Mono, and others).

2001-12-22  Detlef Würkner  <[e-mail]>

	* builds/amiga/*: Adaptations to latest changes.
	Support added for MorphOS.

2001-12-22  Werner Lemberg  <[e-mail]>

	* src/pshinter/pshrec.c (FT_COMPONENT): Redefine to `trace_pshrec'.
	(ps_mask_table_merge, ps_hints_open, ps_hints_stem,
	ps_hints_t1stem3, ps_hints_t2mask, ps_hints_t2counter): Fix
	FT_ERROR messages.
	* src/pshinter/pshalgo1.c (FT_COMPONENT): Define as
	`trace_pshalgo1'.
	* src/pshinter/pshalgo2.c (FT_COMPONENT): Define as
	`trace_pshalgo2'.
	* include/freetype/internal/ftdebug.h (FT_Trace): Updated.

	* docs/modules.txt: New file.
