Currently, the way to do this is:

    * Visit:
        http://hackage.haskell.org/package/QuickCheck-2.1.1.1

    * Visit:
        http://hackage.haskell.org/package/QuickCheck-2.1.0.3

And note any differences in the documentation.

Hackage doesn't yet provide support for changelogs. However, it does
provide support for repository links, from which we can construct a
changelog. That's right: you have to read each repo to get the full
changelog, unless the author has been nice to add it to the .cabal file.

I think what we need is: 

    * Every HP package has to have a .cabal file with the source
      repository type and link.

If we have the source repo and type, I can write a tool to extract the
changelogs between each release automatically.

E.g.
    * darcs
    * http://code.haskell.org/QuickCheck/

>From here we can:

    $ darcs get http://code.haskell.org/QuickCheck/

And running darcs changes:

    * Bump version number

    Thu Jun 17 06:53:22 PDT 2010

    * library
