Not many changes this month but this may have to do with the fact that I didn't had time to explore the OpenGL implementations. Two bugs have been fixed in the AMD implementation and we will particularly enjoy that rendering without vertex array is now supported which is particularly convenient for image space processing but it could also find further usages that are waiting to be explored.
The AMD Catalyst 11.10 drivers released today are not OpenGL 4.2 drivers.
These tests have been done on Seven 64 with the OpenGL Samples Pack 4.2.1.1.
