add PE_REF macro to allow Win32 SIMD for Physics Effects box-boxBoxDistance (although performance hardly differs)
Disable Bullet SAP by default (initialization takes too long, will speed that up later), just compare btDbvt, CUDA and OPCODE broadphases
add 'NextScene' button and minor help in GUI
Raise number of objects to 16384, move all objects at 0.01 speed, to show worst case behaviour (and CUDA benefits)
+ repaired SpuParallellSolverTask: support for warmstarting and added btAssert for constraint sizes that exceed CONSTRAINT_MAX_SIZE
+ Share some more code between SpuParallelSolver and btSequentialImpulseConstraintSolver (both use btSolverBody now)
Lack of warmstarting reported here: http://bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2858
+ allow btBoxBoxDetector to execute on SPU.
some minor fixes for BulletMultiThreaded
cosmetic text fix for ForkLiftDemo
mutable wasn't needed for this anonymous union (btBroadphasePair)
fix in (unused) operator ==
Fix issue with un-initialized broadphase proxy during broadphase insert. It was an chicken-egg problem: 

1) creating a broadphase proxy -> adding pairs during insertion. But during this pair insertion, the btGhostObject broadphase handle isn't set yet (it is done in step 2)
2) assign the broadphase proxy to btGhostObject
Thanks to ihar3d for the report http://bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2864
moved a few Extras projects into Extras/obsolete.
Added IBM Cell SDK 2.x software_cache to Bullet/Extras. There is an option to enable it for the BulletMultiThreaded Cell version.
See USE_SOFTWARE_CACHE in Bullet\src\BulletMultiThreaded\SpuNarrowPhaseCollisionTask\SpuGatheringCollisionTask.cpp
It improves the Bullet midphase collision detection (triangle/vertex fetch)
The license is CommonPublicLicense-1.0, see included license docs.
removed unused files, accidently copied wrong license header in them.
added missing license in headers
Add support for broadphase acceleration of convex cast (re-use rayTest implementation with an added aabb min/max, zero for rays)
Add Concave Convexcast demo back in AllBulletDemos, and tweaked it a bit.
Fix view frustum of ForkLiftDemo (caused picking to fail)
Removed innerloop profiling for ray and convex casts, it hurts performance.
Set default #aabb's in CDTestFramework to 8192
Made btCollisionWorld::convexSweepTest and btGhostObject::convexSweepTest consistent. Both have an optional last argument for allowedCcdPenetration.
Bugfix due to recent change in friction in constraint solver.
minor update in Bullet user manual (needs a lot of work)
added missing Jamfile
duplicate class name causes crashes, thanks to Nado and mickey for the report

CPU implementation of btCudaBroadphase added. 
It is called bt3DGridBroadphase and btCudaBroadphase is now derived from it rater than from btSimpleBroadphase
Test of bt3DGridBroadphase was added to CDTestFramework
