revert to 2.6?

Is there anyway to revert to 2.6 from 3.1? I can’t find a download link. I’m not worried about reverting the project back I just need the install for 2.6.

I plan on moving to 3.1, but due to changes to the way the physics behaves I would rather use that time to finish up this new version I’m working on and get it stable on 2.6 then move to 3.1 after that release.

Thanks in advance.
