I've prepared the 1.20 release candidates. I now need some help testing, especially on Windows as I don't have a Windows machine.

To install the release candidates simply run:

    cabal install http://johantibell.com/files/Cabal-1.20.0-rc.tar.gz http://johantibell.com/files/cabal-install-1.20.0-rc.tar.gz

Please report any issues on the bug tracker: https://github.com/haskell/cabal/issues

If I haven't heard of anything release blocking bugs (or last minute important patches) in a couple of days, I will make these tarballs the official release.

The commits used are tagged in the repo as Cabal-v1.20.0-rc and cabal-install-v1.20.0-rc.
