Well that's about bloody time. Other than that and ES compatibility there doesn't seem to be much of interest though? Or am I missing something?
Well even if there isn't much new, the OpenGL 4.1 release has had a pretty cool effect on OpenGL's image. It certainly now feels as if OpenGL is back in the game, regular updates, massive crossplatform support behind it, seems even better now that ES and OpenGL are unified. Also with some of the small changes in 4.1 we can see Khronos are now starting to weave OpenCL much more closely into OpenGL too.
Khronos dropped the ball a little with 3.0 release but seems they've made up for most of it.
OpenGL now looks far better then DirectX both technically and in terms of support behind it.
