+LATEST CHANGES BETWEEN 2.0.3 and 2.0.3
+
+  I. CHANGES TO THE MODULES / FONT DRIVERS :
+  
+    - THE AUTO-HINTER HAS BEEN SLIGHTLY IMPROVED, in order to fix several
+      annoying artefacts, mainly:
+      
+        - blue zone alignement of horizontal stems wasn't performed
+          correctly, resulting in artefacts like the "d" being placed
+          one pixel below the "b" in some fonts like Time New Roman
+          
+        - overshoot thresholding wasn't performed correctly, creating
+          unpleasant artefacts at large character pixel sizes
+          
+        - composite glyph loading has been simplified. This gets rid
+          of various artefacts where the components of a composite glyphs
+          were not correctly spaced.
+          
+      These are the last changes to the current auto-hinting module.
+      A new hinting sub-system is currently in the work in order to
+      support native hints in Type 1 / CFF / OpenType fonts, as well
+      as globally improve rendering
+
+
+    - The PCF driver has been fixed. It reported invalid glyph dimensions
+      for the fonts available on Solaris.
+    
+    - The Type 1, CID and CFF drivers have been modified to fix the
+      computation of the EM size
+
+    - The Type 1 driver has been fixed to avoid a dangerous bug that
+      crashed the library with non-conforming fonts (i.e. ones that
+      do not place the .notdef glyph at position 0)
+
+    - The TrueType driver had a rather subtle bug (dangling pointer when
+      loading composite glyphs) that could crash the library in rare
+      occasions !
+
+
+  II. HIGH-LEVEL API CHANGES :
+                              
+    - the error code enumeration values have been changed. An error
+      value is decomposed in a generic error code, and a module number.
+      see <freetype/fterrors.h> for details     
+
+    - a new public header file has been introduced, named FT_TRIGONOMETRY_H
+      (include/freetype/fttrig.h), providing trigonometric functions to
+      compute sines, cosines, arctangents, etc.. with 16.16 fixed
+      precision. The implementation is based on the CORDIC algorithm
+      and is very fast while being sufficiently accurate.
+
+
+  III. INTERNALS :
+             
+    - added BeOS-specific files in the old build sub-system. Note that
+      no changes were required to compile the library with Jam.
+
+    - the configuration is now capable of automatically detecting 64-bit
+      integers on a set of predefined compilers (GCC,Visual C++,Borland C++)
+      and will use them by default. This provides a small performance
+      boost
+
+    - a small memory leak that happened when opening 0-sized files (duh !!)
+      have been fixed..
+          
+    - fixed bezier stack depth bug in the routines provided by the
+      FT_BBOX_H header file. Also fixed similar bugs in the rasterizers.
+
+    - the outling bounding box code has been rewritten to use direct
+      computations, instead of bezier sub-division, to compute the
+      exact bounding box of glyphs. This is slightly slower but more
+      accurate.
+
+    - The build system has been improved and fixed, mainly to support "make"
+      on Windows 2000 correctly, avoid problems with "make distclean" on
+      non Unix systems, etc..
+      
+    - hexadecimal constants have been suffixed with "U" to avoid problems
+      with certain compilers on 64-bit platforms.
+
+    - a new directory named "src/tools" has been created. It contains
+      Python scripts and simple unit test programs used to develop the
+      library.
+      
+    - the DocMaker tool has been moved from "docs" to "src/tools" and
+      has been updated with the following:
+      
+         - now accepts the "--title=XXXX" or "-t XXXX" option from the
+           command line to set the project's name in the generated
+           API reference
+           
+         - now accepts the "--output=DIR" or "-o DIR" option from the
+           command line to set the output directory for all generated
+           HTML files
+           
+         - now accepts the "--prefix=XXXX" or "-p XXX" option from the
+           command line to set the file prefix to use for all generated
+           HTML files.
+
+         - now generates the current time/data on each generated page
+           in order to distinguish between versions.
+
+      DocMaker can be used with other projects now, not only FT2
+      (e.g. MLib, FTLayout, etc..)
+
