+LATEST CHANGES BETWEEN 2.1.0 and 2.0.9
+
+ I. IMPORTANT BUG FIXES
+
+ - The TrueType bytecode interpreter has been fixed to produce
+ _exactly_ the same output as FreeType 1.x. Previous differences
+ were due to slightly distinct fixed-point computation routines
+ used to perform dot products and vector length measurements.
+
+ It seems that native TrueType hinting is _extremely_ sensitive
+ to rounding errors. The required vector computation routines have
+ been optimized and placed within the "ttinterp.c" file.
+
+
+ II. NEW FEATURES
+
+ - The 'configure' script used on Unix systems has been modified to
+ check that GNU Make is being used to build the library. If not,
+ it will display a message proposing to use the GNUMAKE environment
+ variable to name it..
+
+ The Unix-specific file README.UNX has been modified accordingly
+
+
+ III. MISCELLANEOUS
+
+ - The FreeType License in 'docs/FTL.txt' has been updated to include
+ a proposed preffered disclaimer. If you're using FreeType in your
+ products, you're encouraged (but not mandated) to use the following
+ text in your documentation:
+
+ """
+ Portions of this software are copyright © 1996-2002 The FreeType
+ Project (www.freetype.org). All rights reserved.
+ """
+
+
+ - The default size of the render pool has been reduced to 16 Kb. This
+ shouldn't result in any noticeable performance penalty, unless you're
+ using the engine as-is to render very large and complex glyphs..
+
+
+ - The FreeType 2 Re-Design has begun. More information can be found
+ at the following web address:
+
+ http://www.freetype.org/freetype2/redesign.html
+
+ The following internal changes have been performed within the sources
+ of this release:
+
+ - many internal types have been renamed to increase consistency.
+ the following should be true, except for public types:
+
+ * all structure types have a name ending in "Rec" (short for
+ 'record').
+
+ * a pointer-to-structure type has the same name than the
+ structure, _without_ the "Rec" suffix.
+
+ for example:
+
+ typedef struct FooRec_
+ {
+ ....
+
+ } FooRec, *Foo;
+
+ - many internal macros have been renamed to increase consistency.
+ the following should be true:
+
+ * all macros have a name beginning in "FT_". This required
+ a few changes like:
+
+ ALLOC => FT_ALLOC
+ FREE => FT_FREE
+ REALLOC => FT_REALLOC
+
+
+ * all macro are completely UPPERCASE. This required a few
+ changes like:
+
+ READ_Short => FT_READ_SHORT
+ NEXT_Short => FT_NEXT_SHORT
+ GET_ULongLE => FT_GET_ULONG_LE
+ MEM_Set => FT_MEM_SET
+ MEM_Copy => FT_MEM_COPY
+ etc..
+
+ * whenever possible, all macro names follow the FT_<OBJECT>_<METHOD>
+ pattern. For example:
+
+ ACCESS_Frame => FT_FRAME_ENTER
+ FORGET_Frame => FT_FRAME_EXIT
+ EXTRACT_Frame => FT_FRAME_EXTRACT
+ RELEASE_Frame => FT_FRAME_RELEASE
+
+ FILE_Pos => FT_STREAM_POS
+ FILE_Seek => FT_STREAM_SEEK
+ FILE_Read => FT_STREAM_READ
+ FILE_ReadAt => FT_STREAM_READ_AT
+ READ_Fields => FT_STREAM_READ_FIELDS
+
+
+ - many internal functions have been renamed to follow the
+ FT_<Object>_<Method> pattern. For example:
+
+ FT_Seek_Stream => FT_Stream_Seek
+ FT_Read_Stream_At => FT_Stream_ReadAt
+ FT_Done_Stream => FT_Stream_Close
+ FT_New_Stream => FT_Stream_Open
+ FT_New_Memory_Stream => FT_Stream_OpenMemory
+ FT_Extract_Frame => FT_Stream_ExtractFrame
+
+ note that method names do not contain "_".
+
+
+ - the FT_ALLOC_ARRAY and FT_REALLOC_ARRAY have been removed and
+ are now replaced by FT_NEW_ARRAY and FT_RENEW_ARRAY which do
+ not take a type as the fourth argument. Instead, the array
+ element type size is computed automatically from the type
+ of the target pointer used.
+
+
+ - a new object class, named FT_CMap has been introduced. These
+ internal objects are used to model character maps. This eases
+ the support of additional charmap types within the engine
+
+
+ - a new configuration file named "ftstdlib.h" has been added
+ to 'include/freetype/config'. It is used to define aliases
+ for _every_ routine of the ISO C library that the font engine
+ uses. Each aliases has a "ft_" prefix (e.g. "ft_strlen" is an
+ alias for "strlen").
+
+ this is used to ease the porting of FT2 to exotic runtime
+ environments where the ISO C Library isn't available (e.g.
+ XFree86 extension modules).
+
+
+
+ More details are available in the "ChangeLog" file.
