+ Added split impulse support, penetration recovery won’t add momentum
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.

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.
Jezek announced a new release of JBullet, a Java port of Bullet. You can check the demos on-line:
Notes: requires Java 5.0, needs permissions for OpenGL rendering
Bullet 2.67 is available now from http://code.google.com/p/bullet/
The SVN repository is sychronized with the existing sourceforge repository.
Development is ongoing, and outstanding issues will roll into upcoming releases.

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 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.
NVidia released a VisSim demo to showcase NVSG. They showed this demo in the NVidia booth at SIGGRAPH 2007 in San Diego.
Quote from the website: “The demo illustrates the integration of Physics (Bullet physics system), Audio (OpenAL), and Graphics through Producer, Cal3D, FreeType and of course NVSG. Bullet, OpenAL and Producer are all open source projects that are available from their respective repositories on the Internet. Nvidia and the NVSG team do not endorse any of these projects specifically, but they have worked very well for us and we would certainly recommend them. The source code to the VisSim demo is available below.”
“Most interesting of the desired features, however, is the development of Capcom’s own physics system to replace the Havok middleware that it currently uses. ”
Explaining the decision, the page states that “Although middleware might increase efficiency, language discrepancies, response times for support/bugs and the loss of understanding on how our entire engine is structured leads us to feel that we get better results in a shorter period by developing our own engine.”
