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

There are over 300 commits since the last release and lots of interesting new features and changes. I will write them down when I make the actual release.

To install the release candidates simply run:

    cabal install --constraint="HTTP >= 4000.2.5" http://johantibell.com/files/Cabal-1.20.0-rc.tar.gz http://johantibell.com/files/cabal-install-1.20.0-rc.tar.gz

(The --constraint="HTTP >= 4000.2.5" flag is used to work around an issue I already found in the RC, it won't be needed for the real release.)

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.
