+
+	* Version 2.9 released.
+	=======================

+
+	* include/freetype/freetype.h (FREETYPE_MINOR): Set to 9.
+	(FREETYPE_PATCH): Set to 0.
+
+	* builds/unix/configure.raw (version_info): Set to 22:0:16.
+	* CMakeLists.txt (VERSION_PATCH): Set to 1.
+
+2018-01-07  Werner Lemberg  <wl@gnu.org>
+
+	Add check for librt, needed for `ftbench' (#52824).
+
+	* builds/unix/configure.raw (LIB_CLOCK_GETTIME): Define; this will
+	hold `-lrt' if necessary.
+
+	* builds/unix/unix-cc.in (LIB_CLOCK_GETTIME): New variable.
+
+2018-01-07  Ewald Hew  <ewaldhew@gmail.com>
+
+	[psaux] Fix Type 1 glyphs with too many stem hints.
+
+	According to the CFF specification, charstrings can have up to 96 stem
+	hints. Due to hint replacement routines in Type 1 charstrings, some
+	glyphs are rejected by the Adobe engine, which implements the above
+	limit. This fix turns off hinting for such glyphs.
+
+	* src/psaux/pshints.c (cf2_hintmap_build): Reset the error from calling
+	`cf2_hintmask_setAll' on a problematic Type 1 charstring and turn off
+	hinting.
+
+2018-01-06  Werner Lemberg  <wl@gnu.org>
+
+	Add `FT_Done_MM_Var'.
+
+	This is necessary in case the application's memory routines differ
+	from FreeType.  A typical example is a Python application on Windows
+	that calls FreeType compiled as a DLL via the `ctypes' interface.
+
+	* include/freetype/ftmm.h, src/base/ftmm.c (FT_Done_MM_Var): Declare
+	and define.
+
+	* docs/CHANGES: Updated.
+
+2018-01-03  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Round offsets of glyph components only if hinting is on.
+
+	* src/truetype/ttgload.c (TT_Process_Composite_Component): Implement
+	it.
+
+2018-01-03  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttgxvar.c (ft_var_to_design): Remove dead code.
+
+	This is a better fix than the previous commit, which is now
+	reverted.
+
+2018-01-03  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	Move internal LCD-related declarations.
+
+	* include/freetype/ftlcdfil.h (ft_lcd_padding, ft_lcd_filter_fir):
+	Move from here...
+	* include/freetype/internal/ftobjs.h: ... to here.
+
+2018-01-03  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	* include/freetype/config/ftconfig.h (FT_EXPORT, FT_EXPORT_DEF)
+	[_MSC_VER]: Limit Visual C++ attributes.
+
+2018-01-03  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Make blend/design coordinate round-tripping work.
+
+	Behdad reported that setting blend coordinates, then getting design
+	coordinates did incorrectly return the default instance's
+	coordinates.
+
+	* src/truetype/ttgxvar.c (tt_set_mm_blend): Fix it.
+
+2017-12-31  Werner Lemberg  <wl@gnu.org>
+
+	* src/sfnt/ttcmap.c (tt_cmap2_char_next): Fix endless loop.
+
+	Reported as

+
+	Use Adobe hinting engine for `light' hinting of both CFF and Type 1.
+
+	Since Ewald Hew factored the Adobe hinting engine out of the CFF
+	driver code, we can now use it on Type 1 (and CID) font formats, as
+	both have the same hinting philosophy.
+
+	This change activates the Adobe hinter when in LIGHT mode, and
+	therefore always unless explicitly asking for the auto-hinter.  This
+	makes LIGHT behavior consistent with CFF fonts.  As of this commit,
+	the hinting engine table looks as follows.
+
+	             LIGHT  NORMAL

+
+	The interpreter in Type 1 mode rewinds the charstring after collecting

+	[cff, truetype] Adjust behaviour of named instances.
+
+	This commit completely separates the interaction between named

+
+	As a side effect, variation functions no longer change the named

+	[cff] Fix family name logic of pure CFF fontdata (#52056).
+
+	1. If `FamilyName' is present in the CFF font, use this for
+	   FT_Face's `family_name'.
+	2. Otherwise, use the face name and chop off any subset prefix.
+	3. If at this point FT_Face's `family_name' is set, use this
+	   together with the full name to determine the style.
+	4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.
+	5. If we don't have a valid style, use "Regular".
+
+	Previously, FT_Face's `family_name' entry for pure CFF fontdata
+	nearly always was the fontname itself, instead of the `FamilyName'
+	entry in the CFF font (assuming there is one).

+	* src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.

-	[gzip] Improve building with external zlib (#49673).
-
-	Building FreeType with external zlib 1.2.8 makes msvc 14 stop with
-	the following error.
-
-	  ftgzip.c
-	  zlib-1.2.8\zlib.h(86): error C2061:
-	                         syntax error: identifier 'z_const'
-	  zlib-1.2.8\zlib.h(94): error C2054:
-	                         expected '(' to follow 'z_const'

-	                          error count exceeds 100; stopping compilation
-
-	The error happens because FreeType keeps an own copy of zlib-1.1.4
-	under `src/gzip'.  When building `src/gzip/ftgzip.c' with
-	FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses
-
-	  #include <zlib.h>
-
-	which correctly finds an external `zlib.h', but `zlib.h' itself has
-	a line
-
-	  #include "zconf.h"
-
-	which makes Visual Studio 2015 find `src/gzip/zconf.h' while
-	compiling the files in `src/gzip'.
-
-	* src/gzip/zconf.h: Rename to...
-	* src/gzip/ftzconf.h: ... this.
-	* src/gzip/zlib.h, src/gzip/rules.mk (GZIP_DRV_SRCS): Updated.

-
-	Introduce a way of quickly retrieving (embedded) bitmap metrics.
-
-	`FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph

-
-	[pcf] Enrich family name with foundry name and glyph width info.
-
-	This is a very old patch from openSuSE (from 2006, submitted to
-	FreeType in 2011) that I forgot to apply.
-
-	  https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch
-
-	Prepend the foundry name plus a space to the family name.  There are
-	many fonts just called `Fixed' which look completely different, and
-	which have nothing to do with each other.  When selecting `Fixed' in
-	KDE or Gnome one gets results that appear rather random, the style
-	changes often if one changes the size and one cannot select some
-	fonts at all.
-
-	We also check whether we have `wide' characters; all put together,
-	we get family names like `Sony Fixed' or `Misc Fixed Wide'.
-
-	* src/pcf/pcfread.c (pcf_load_font): Implement it.
-
-	* docs/CHANGES: Document it.

-
-	* docs/CHANGES: Updated.
-
-2016-09-25  Werner Lemberg  <wl@gnu.org>
-
-	[truetype] Sanitize only last entry of `loca' table.
-
-	Without this patch, a loca sequence like `0 100000 0 100000 ...',
-	where value 100000 is larger than the `glyf' table size, makes
-	FreeType handle the whole `glyf' table as a single glyph again and

-
-	[smooth] Fix valgrind warning and reoptimize.
-
-	The algorithm calls `gray_set_cell' at the start of each new contour

-
-	[smooth] Simplify span rendering more.
-
-	It turns out that there is significant cost associated with `FT_Span'
-	creation and calls to `gray_render_span' because it happens so
-	frequently. This removes these steps from our internal use but leaves
-	it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain
-	is about 5%.
-
-	* src/smooth/ftgrays.c (gray_render_span): Removed. The code is
-	migrated to...
-	(gray_hline): ... here.
-
