+(Add new stuff at the top!)
+
+Sept 27th:
+==========
+* Added a 'collisionMap' and pre-populated it with the handles of
+  four of the cubes (which are coloured RED so you can see them).
+* Non-red cubes are painted in shades of blue/green.
+* Every cube (including the red ones) is gravitationally attracted
+  to all four red cubes in inverse proportion to their ranges.
+
+Sept 9th:
+=========
+* Merged in my latest changes into SVN repository.
+* Arranged to avoid reading/writing textures at same time.
+* Removed depth and stencil buffers from FBO's.
+* Eliminated 1-component FBO that caused grief for FBO completeness test.
+* Added back missing cubeShaderNoTexture.vert
+
+------------------- FIRST ADDITION TO SUBVERSION ---------------------
+GPUphysics-0.4
+==============
+
+* Test for availability of vertex shader textures.
+* Fixed 'status: xxxx' message.
+* Added support for running the demo in the absence of vertex shader textures.
+
+GPUphysics-0.3
+==============
+
+* Use signed initial velocities so everything doesn't slide off the screen!
+* The 'bounce' now slows down X/Z motion as well as Y so things actually
+  do stop moving eventually.
+* Caught up with some portability issues for more recent versions of
+  GLSL.
+
+GPUphysics-0.2
+==============
+
+* Added MacOSX support.
+* Added a ton of command-line debug options (see DEBUG_README)
+* Changed to ZLib license.
+
+GPUphysics-0.1
+==============
+
+* Fixes for stencil buffer problems on some systems.
+
+GPUphysics-0.0
+==============
+
+* Initial release
