+ Added split impulse support, penetration recovery won’t add momentum
+ cloth/soft body improvements: picking (pick and drag), tearing (click and release without mouse move), preliminary support for btSoftBody versus compound and concave trimesh
+ Added new btDbvtBroadphase, based on dynamic AABB tree. It has the capability to do view frustum culling and front-to-back traversal. See Extras\CDTestFramework for view frustum culling sample.
+ Enabled new btGjkEpa2 penetration depth solver, thanks to Nathanael
+ Provide access to all persistent manifolds for a given btBroadphasePair, see CharacterDemo for sample usage
+ Added linear and angular motor for btSliderConstraint
+ Add penetration depth test for convexSweepTest
+ removed several warnings for Windows build, thanks to Martijn Reuvers
+ Added Mac Cocoa Xcode project, thanks to TomorrowPlus
+ use collision margin of btBvhTriangleMeshShape for convexTest, Thanks to reltham for the contribution.
+ added custom memory allocator registration, thanks to Sly.
Download Bullet 2.69 from the Bullet repository at Google Code.
+ New BulletSoftBody library: cloth, rope and deformable volumes, including interaction with rigid bodies. Thanks Nathanael Presson.
+ Added btSliderConstraint
+ Added Extras/CdTestFrameWork, Thanks Pierre Terdiman
+ Added posix thread support (pthreads), Thanks Enrico.
+ Moved ConvexHull into Bullet/src
+ Moved optional quickstep and box-box collision detector to Bullet/src. Thanks Russell Smith for permission to re-distribute under the ZLib license.
+ Many bugfixes and improvements to BulletColladaConverter, btSubsimplexConvexCast, btMultiSapBroadphase, btOptimizedBvh

Wolfgang Engel developed the Oolong Engine 2 for iPhone, and initial Bullet support looks very promising. Unlike most other phones, the floating point performance of the iPhone is very good.
Thanks everyone for the hard work and feedback,
Bullet 2.67 is available now from http://code.google.com/p/bullet/
- Add support for fast batch raycasting on SPU / BulletMultiThreaded
- Add support for 16 and 32-bit indexed triangle meshes in SPU / BulletMultiThreaded version.
- Improved COLLADA Physics export snapshot from any Bullet btDynamicsWorld. Saving the physics world into .dae (xml textfile) can be useful for debugging etc.
- Initial version for Character Control Demo
- Bugfixes in ConvexCast support against the world.
- Added btCapsuleShapeX/Z
- Added btTypedUserInfo, useful for serialization
- Added Stan Melax Convex Hull utility library in Extras/ConvexHull. This is useful to render non-polyhedral convex objects, and to simplify convex polyhedra.
The SVN repository is sychronized with the existing sourceforge repository.
Development is ongoing, and outstanding issues will roll into upcoming releases.

The slides for the Game Developers Conference 2008 Tutorial, Physics for Game Developers, on parallel SPU physics are available for download now.
For feedback please use the
Physics Simulation Forum
Following link provides some physics related sessions during upcoming GDC. There will be some demos of Bullet physics at the showfloor. It is a nice occasion to meet up, so if you are around, please get in touch!
More details here.
One of the distinguished projects at the Department of Computing at Imperial College London is about real-time physics simulation, using the Bullet physics library as case study.
At a first glance it looks like an interesting read!
The new CUDA 1.1 SDK includes some new physics demos including particle systems, FFT-based 2D fluids, and n-body gravitational simulation, all running on the GPU.
Thanks to Simesgreen for the link
The project contains a small library that connects the Bullet Physics Engine to the Horde3D Graphics Engine.
The source code contains also a little example application and a patch for the Collada Converter of the Horde3D Engine version 0.11 that allows the usage of basic features of the Collada Physics extension.
This text is also available in german. A local cached copy of the source/demo is available too.
