-- Haddock 2.4.2

A new version of Haddock, the Haskell documentation tool, is out.

This is a bug fix release only, and it's the same version that will ship with
GHC 6.10.2, unless any important problems are discovered before the GHC

Because the .haddock file format has changed, links to previously installed
documentation will not work when generating documentation using this version.

Please use the bug tracker to submit bug reports or feature requests.

-- Changes in version 2.4.2
