They were fully functional at the time of their use (display lists & all). You can hardly expect a banshee to support the latest opengl versions however. If you're referring to the current level of support (and I'll use opengl as an example here) - I'm pretty sure everyone who can support the latest version already does. And we'll exclude opengl 3.2 from that list (considering the spec hasn't even been released yet). I find it interesting in that regard that the nvidia drivers put the version number in there - whilst true that it will likely include everything in 3.2, it's still a little pre-emptive.
No announcement yet.
