#Bregma - actually Mesa doesn't support full OpenGL 4 features yet, they are work in progress.They allow OpenGL 3.1 level feature set in release 9.2, although I know that even some OpenGL 4.x level extension are implemented.

The problem is, Ubuntu is using old version in their packages.

We ship Mesa 9.2, released August 27, 2013, in Ubuntu "Saucy Salamander". That doesn't seem all that old to me, considering it's the latest version released. Of course, you might be using an older release of Ubuntu, which consists of older packages.

But I stand corrected, Mesa supports only OpenGL 3.1 (and OpenGL|ES 3).

My laptop has an Intel GMA 965 which on FreeBSD glxinfo reports version 2.0 and on OpenBSD it reports 2.1 (I guess OpenBSD is ahead of FreeBSD for graphics drivers for some reason) :/

Regardless I find using glew with 2.1 pretty ideal. There are not really any major restrictions to be encountered
An interesting test to sanity check my OpenGL code is using Emscripten and outputting to a web browser which only supports OpenGL ES 2.0 and is pretty strict.

However, I am really curious about the OpenGL SC 1.3 standard (http://www.khronos.org/openglsc). Is this possible on consumer hardware? In which case we can no longer call OpenGL 1.3 "legacy" ;)
