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__ + 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__ 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. + + LATEST CHANGES BETWEEN 2.0.9 and 2.0.8 I.
