+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 6.1) designate new developmental releases.
+Even numbered versions (such as 6.0) designate stable releases.
+
+
+New Features
+------------
+
+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
+
+
+
+Driver / context changes
+------------------------
+
+The _mesa_create_context() and _mesa_initialize_context() function
+parameters have changed.  They now take a pointer to a struct
+dd_function_table.  Drivers can initialize this table by calling
+_mesa_init_driver_functions().  Drivers should then plug in the special
+functions they implement.  In particular, the ctx->Driver.NewTextureObject
+pointer _must_ be set so that the default texture objects created in
+_mesa_create/initialize_context() are correctly built.
+
+The _mesa_init_driver_functions() function allows a lot of redundant code
+to be removed from the device drivers (such as initializing
+ctx->Driver.Accum to point to _swrast_Accum).  Adding new functions to
+the dd_function_table can be done with less hassle since the pointer can
+be initialized in _mesa_init_driver_functions() rather than in _all_ the
+drivers.
+
+
+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:
+
+Driver			Status
+----------------------	---------------------
+XMesa (Xlib)		implements OpenGL 1.5
+OSMesa (off-screen)	implements OpenGL 1.5
+Glide (3dfx Voodoo1/2)	implements OpenGL 1.3
+SVGA			implements OpenGL 1.3
+Wind River UGL		implements OpenGL 1.3
+Windows/Win32		implements OpenGL 1.5
+DJGPP			implements OpenGL 1.5
+GGI			implements OpenGL 1.3
+BeOS			implements OpenGL 1.5
+Allegro			needs updating
+D3D			needs updating
+
