What is this new OpenGL 3.0 thing. I heard a lot of functions are depracted now and should not be uses anymore? How does this impact developing OpenGL applications. Will thing work more like OpenGL ES?
Is there a quick introduction on migrating to OpenGL 3.0 ?
Also how does this impact on supporting older hardware? Need two or more opengl paths in your application? One for old skool opengl and one for OpenGL 3.0?
OpenGL 3.0 requires DX10 Hardware. Currently there are only beta drivers for nvidia cards. It won't be a bad idea to read the forums on http://opengl.org for more informations.
What i find stupid is that they say that the reasons for Deprecation is that it means that GFX Card manufacturors don't have to support all the old methods, meaning less buggy patches etc. But they will now have to support Pre 3.0 and 3.0 at the same time or else Gamers who buy the latest cards will moan that they now can't play the current generation of games on there GFX Card because they weren't made for OGL 3.0 . Which means more buggy GFX drivers and more wasted time by the GFX Card manufacturors.
NVIDIA will take full advantage of the mechanism described in question #2 to keep supporting all functionality, including functionality on the deprecated list in OpenGL 3.0, for all future OpenGL versions. If, for example, OpenGL 3.1 will actually remove the features on the deprecated list, developers will be able to keep using those features on NVIDIA hardware using one of the mechanisms described in question #2.
I fail to see the point of deprecating features when NVidia states that it will support all deprecated features..... I assume ATI will do the same so they don't loose some ground.

Look at this site http://developer.nvidia.com/object/opengl_3_driver.html.
Some functions are marked as deprecated but nothing was removed.
The most interesting features are new more solid FBO, GLSL 1.2 and Texture Arrays.
Every feature you can use with gf8800 cards on OpenGL2.1 as extension.
