     - Various memory leaks have been found and fixed.
 
+    - Fixed the TrueType name loader that didn't deal properly with some
+      fonts that encode their names in UTF-16 (the spec was vague, and
+      the code assumed UCS-4)
+
+    - Fixed the TrueType bytecode loader to deal properly with subtle
+      monochrome/gray issues when scaling the CVT. Some fonts exhibited
+      bad rendering artefacts otherwise.
+
+    - FT_GlyphSlot_Embolden now supports vertical layouts correctly
+      (it mangled the vertical advance height)
+
+  II. NEW API FUNCTIONS
+
+    - FT_Library_SetLcdFilter allows you to select a special filter to
+      be applied to the bitmaps generated by FT_Render_Glyph when one
+      of FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V is used. This
+      filter is used to reduce color-fringes, several settings are
+      available through the FT_LCD_FILTER_XXX enum.
+
+      See its declaration and documentation in FT_LCD_FILTER_H, a.k.a.
+      include/freetype/ftlcdfil.h.
+
+      *IMPORTANT*: note that this function returns an error 
+      (FT_Err_Unimplemented_Feature) in default builds of the library
+      for patent reasons. See below
+
+
+    - FT_Get_Gasp allows you to query the TrueType GASP flags for a
+      given character pixel size. This is only useful to duplicate
+      Windows' text rendering, when the native bytecode interpreter is
+      enabled (which still isn't the default for other patent reasons)

+  III. IMPORTANT CHANGES
+
+    - The auto-hinter has been severely tuned to improve its results
+      with serif fonts. This results in much better font rendering of
+      many web pages.

       The  displayed result  should  be equal  to normal  anti-aliased

+      Additionally, if FT_CONFIG_OPTION_SUBPIXEL_RENDERING is not

     - Some computation bugs in  the TrueType bytecode interpreter were
       found,  which  allow us  to  get rid  of  very  subtle and  rare
       differences we had experienced with the Windows renderer.
 
 
+    - It's now possible to cross-compile the library easily. See the

   III. MISCELLANEOUS
 
-    - TrueType glyph loading is now about 25% faster.
+    - Various performance and memory footprint optimizations have been
+      performed on the TrueType and CFF font loaders, sometimes with
+      very drastic benefits (e.g. the TrueType loader is now about
+      25% faster, FreeType should use less heap memory in nearly all
+      conditions)
