Versace talked more about Waffle back at XDC last month in Germany.
The Waffle 1.1 release provides support for a new Linux platform, which is using EGL directly with GBM. When using EGL with the Graphics Buffer Manager in Mesa, OpenGL applications can run directly with Waffle and don't require a running display manager. Waffle 1.1.0 also adds experimental support for Google's Android operating system while not breaking backwards compatibility with Waffle 1.0. As a dessert to Waffle 1.1, the public API is now fully documented in the man pages.
The Waffle 1.1 announcement can be viewed on mesa-dev.
