root pages should redirect to versioned pages about matplotlib.github.com

Soft links definitely do not work - I tested on GitHub pages, and the GitHub pages are transparent to the soft links.

I would avoid the redirect; people tend to copy-past link in SO and GitHub, it's usually better to even redirect the other way, or at least have the rel=canonical point to /latest/ this push google to better index latest.

Though I agree that a /latest/ and/or /stable/ prefix would be nice.

I'll re-open because we still haven't done the redirect

We now have /stable/ redirecting to /3.3.3/ which is good. However, "canonical" is listed as 3.3.3. Suggest instead that "canonical" be /stable/. This will require post-processing the html files upon release, but it is easy to write a python script to do that.

For reference, google will suggest the canonical link, but we are really confusing it by having 3.3.3 be canonical and 3.3.2 also canonical. So what happens is the version of the docs that was referenced the most ends up the top search.
