Carl Worth of Intel's Open-Source Technology Center announced Mesa 10.3-RC1 this morning. Leading up to the official release will now be weekly release candidates. "Mesa 10.3 release candidate 1 is now available for testing. The current plan is to have an additional release candidate each Friday until the eventual 10.3 release, (Ian can follow up to state what the planned date is for that)."
Mesa 10.3 brings many performance improvements, more OpenGL 4.x functionality, the VC4 Gallium3D driver, and much more. A separate article on Phoronix in the days ahead will recap the Mesa 10.3 improvements and we'll still keep delivering fresh Mesa 10.3 benchmarks against the current stable releases as we have been doing for the past weeks.
With Mesa 10.3 RC1 happening, Mesa Git master is now Mesa 10.4-devel. Mesa has been sticking to a three-month release cadence, but if OpenGL 4.0 compliance is reached in time, this next version will end up being called Mesa 11.0. Per the GL3.txt file, OpenGL 4.0 support is getting incredibly close for modern Intel hardware on Linux.
