+2010 July 21
+  - Preparing for Bullet 2.77 release, around revision r2135
+  - Added an OpenCL particle demo, running on NVidia, AMD and MiniCL
+    Thanks to NVidia for the original particle demo from their OpenCL SDK
+  - Added GPU deformable object solvers for OpenCL and DirectCompute, and a DirectX 11 cloth demo
+    Thanks to AMD
+  - Create a separate library for MiniCL, 
+    MiniCL is a rudimentary OpenCL wrapper that allows to compile OpenCL kernels for multi-core CPU, using Win32 Threads or Posix
+  - Moved vectormath into Bullet/src, and added a SSE implementation
+  - Added a btParallelConstraintSolver, mainly for PlayStation 3 Cell SPUs (although it runs fine on CPU too)

 	- Dynamica Maya plugin (and COLLADA support) is moved to http://dynamica.googlecode.com
