The most notable commit this morning is perhaps the Nouveau NVC0 (Fermi+) driver supporting OpenGL multi-sample textures, thanks to work done by Christoph Bumiller with this commit.
Multi-sample texture support within the Gallium3D/Mesa drivers is relatively new: Intel got it last month while Radeon Gallium3D has had it since January. The GL_ARB_texture_multisample extension is mandated by the OpenGL 3.2 specification. The registry specification on the extension can be viewed at OpenGL.org.
Aside from the NVC0 multi-sample textures, there were several other Nouveau Gallium3D commits pertaining to NVC0 and NV50 too.
