Comment (by simonmar):

 I'd like to do this automatically with tool support.  For example, we can
 retain the `.haddock` files for previous versions of a package, and
 Haddock can infer when particular entities were introduced, and add the
 appropriate annotations.  IIRC Hoogle has some functionality that could be
 used for this too.

 Related to this is the need to compare APIs for determining whether
 version bumps are necessary.  We should therefore have a way to dump an
 API in a machine-readable format for use by Haddock and other tools.
