 New Features
 ------------
 
-TBD
+Half-precision floating point (GLhalf) pixel formats are supported
+in Mesa, but the feature isn't exposed yet since the ARB extension
+hasn't been finalized yet.
+
+
+Texture image handling
+----------------------
+
+The code which implements image conversion, pixel transfer ops, etc
+for glTexImage commands has been rewritten.
+
+Now the gl_texture_format struct has a new StoreImage function
+pointer.  Each texture format must implement this function.  The
+function is totally responsible for converting the user's texture
+image into the specific format.  A few helper functions makes this
+relatively simple.
+
+Overall, the code is much simpler, cleaner and easier to work with
+now.  Adding new texture formats is straight-forward and there's no
+longer any distinction between "hardware" and "software" formats.
+
+Finally, the code for compressed texture images has been reorganized
+as well.
+
+Removed files:
+  texutil.c
+  texutil.h
+  texutil_tmp.h
+
+New files:
+  texcompress_s3tc.c
+  texcompress_fxt1.c

 Device Drivers

+Mesa advertises itself as supporting OpenGL 1.2, 1.3, 1.4 or 1.5
+depending on the device driver's capabilities.  For example, if the
+driver enables all the ARB extensions which are part of OpenGL 1.5
+then glGetString(GL_VERSION) will return "1.5".  Otherwise, it'll
+return "1.4" or the next lower version that implements all required
+functionality.
 
 A number of Mesa's software drivers haven't been actively maintained for
 some time.  We rely on volunteers to maintain many of the drivers.
 Here's the current status of all included drivers:
