Bug 103212

Good catch, thanks! This allows glxinfo and wglinfo to show 4.6 info :)

I went ahead and create a commit for you, and pushed it:

Next time you have a patch, it would be easier if you sent it to the mailing list instead.
Everything you need to know is explained on our website:

It should work even without the patch. When requesting GL 4.5 (or 3.1 even) the driver is allowed to create a 4.6 context since it's compatible with the requested version.

Regardless, it's a good idea to be explicit imho.

@Eric Engestrom thanks! And also thanks for pointing me to that page in the website.

@Emil Velikov with the NVIDIA proprietary driver glxinfo was showing OpenGL version 4.5, even if the driver supports 4.6

That is probably because OpenGL 4.6 is still only a provisional specification (due to no conformance program yet).  Once the conformance program is in place and 4.6 support moves out of beta, I bet it would just work.
