My free cross platform library Proton SDK (a framework that helps you write C++ apps for iOS, Android, WebOS, Win, and OS X) has quietly been receiving improvements across the board:

• Android support now works with the Android NDK R6 out of the box, Crystax no longer needed.  Binaries still run on Android 1.6+ too!
• Redid the “Setting up Proton to make Android stuff” page using NDK R6 (wrote as I set up my new computer, so it’s pretty accurate)
• HP Touchpad/WebOS 3.0 support added (native touch keyboard automatically pops up when needed, full multi-touch enabled)
• New tutorial added on how to setup GL ES 1.1 emulation on Windows using the latest PowerVR SDK
• Audio systems across all platforms improved
• LoopingSound class added, for playing looping sounds with optional intro/outtro effects
• AudioManagerDenshion added, recommended for iOS and OS X builds
• A new example (RTPhysics) was added a while back, combined Irrlicht 3D with Bullet physics (shoot cubes to knock down a stack)
• Irrlicht under Android improved, now provides seamless automatic reloading of fonts and textures after losing/restoring focus
• Many bugfixes…

Some Proton-based games recently released by other companies:

• Duke Nukem 3D for Touchpad
• Az Sky Defender for Android
