-To Do before release
---------------------
- Fix dinoshade bug
+glDeleteTextures(), glDeletePrograms() and glDeleteBuffers() Changed
+--------------------------------------------------------------------
+
+To match the behaviour of other OpenGL implementations, glDeleteTextures,
+glDeletePrograms and glDeleteBuffers have been modified so that:
+
+  * The named texture/program/buffer ID is immediately freed for re-use.
+
+  * The actual texture object, program or buffers isn't really deleted until
+    it is no longer bound in any rendering context (the reference count
+    is zero).
+
+Previously, the texture/program/buffer ID wasn't freed until the object
+was really deleted.
+
+Note that textures, programs and buffers can be shared by several rendering
+contexts so they can't be deleted until they're unbound in _all_ contexts.
+
+
+
+GL_EXT_framebuffer_object changes
+---------------------------------
+
+Implementing this extension involved changing a lot of code (for the better).
+
+The gl_framebuffer object now a collection of gl_renderbuffer objects.
+Renderbuffers may store colors, stencil indices, or depth values.  The
+gl_framebuffer and gl_renderbuffer types are object-oriented in design.
+
+All the old RGB, color index, stencil and depth-related span functions for
+reading/writing pixels from/to buffers has changed.  Now, all pixels are
+read/written through a set of common renderbuffer functions (methods).
+
+Most device drivers have been updated for these changes, but some haven't.
+
+
+
+To Do (someday) items
+---------------------
  Switch to freeglut
  Increase MAX_DRAWBUFFERS
  driver hooks for BeginQuery/EndQuery
 
 
 
+Miscellaneous
+-------------
+
+The main/get.c file is now generated with a Python script (get_gen.py).
