4026	library documentation has unstable URLs	duncan		"Currently google is returning URLs for ghc libraries that return 404, eg:
http://haskell.org/ghc/docs/latest/html/libraries/base-4.2.0.0/Data-List.html

The new URL is with `base-4.2.0.1` rather than `base-4.2.0.0`.

This is not google's fault, it is our fault. We are using unstable URLs. Of course, we cannot guarantee full stability as modules get added/removed however we can do much better than breaking all URLs every time.

I suggest we have two sets of stable URLs, versioned URLs and ""latest""/unversioned URLs:

{{{
/ghc/docs/6.12.1/html/libraries/base-4.2.0.0/Data-List.html

/ghc/docs/latest/html/libraries/base/Data-List.html
}}}

This will either mean generating them separately so that links between packages work, or using redirects such as:
{{{
/ghc/docs/latest/html/libraries/base-4.2.0.1/
->
/ghc/docs/latest/html/libraries/base/
}}}
so that we can generate the docs once and use them at both the ""latest"" and ghc-versioned locations."	bug	closed	normal		Documentation	6.12.2	fixed			Unknown/Multiple	Unknown/Multiple	None/Unknown
