The 3.1 spec in on the OpenGL site and Nvidia are quick out of the block again announcing their release of the 3.1 driver.

A new __extension__ has been added ARB_compatibility which can be used to check if the depreciated functions listed in the 3.0 spec are supported by the driver, as it is now optional to support them.

Details were posted via twitter

Uhh...I'm not seeing the new spec anywhere.

It's here.
Looks like they added (promoted?) some features and removed immediate mode, but still nothing like the major rewrite that was promised a long time ago for version 3. Is that still in the pipeline or should we forget about that?

Removing all the features they did will allow a major rewrite of the code. It is about what I was expecting. I am guessing 3.0 is a result of the bureaucrat that said just removing features without notice would have been to harsh so they marked them for deletion wait a little while and then deleted them.
I am happy with this, cant wait to see what is added later and how much of a speed improvement this will cause.

Oh, they only link the specs from that page and not anywhere else. Weird.

I think its a bit stupid to provide the backwards extension, now vendors have to support two architectures/implementations and users will have the option to "be lazy" (i know economically this is a good move, but from a progresionist point of view, i think its quite silly)

I will personally continue to use GL and will dump < GL 3.1 support however IMO (Im not saying they ever will, just an oppinion) MS would erradicate GL for games (probably most other things as well...) if they created a supported D3D implementation for nix based OS's - ofcourse this would also mean Sony would have to drop/change their librsx implementation... but yea..

I want Khronos to just focus on not screwing up OpenGL|ES because they are doing well in that regard so far. although leaving out push/pop attrib methods in ES1 was a total brain-fart for obvious reasons - GL is a state machine! and you decide to leave out the client controlled state stack????, so my fear is genuine.

Well they didn't make us wait 8 years so I'm pleased, even if all we are getting is a little tweak. I would rather like lots of little changes gradually than nothing for years and then disappointment with no real changes.

I've never used them and I use std GL. There is quite a lot in GL that I don't use.
