The Travis folks have decided they want to support Haskell better (multiple compiler versions): https://github.com/travis-ci/travis-ci/issues/882#issuecomment-20165378 (Yay!) They're asking for someone to help them up with setup scripts. They mention their cookbook collection here: https://github.com/travis-ci/travis-cookbooks In that thread above, I pasted our little script that fetches and installs multiple GHC versions, but I have little experiences with cloud technologies & VMs. Can someone jump in and help push this forward? As a community I'm sure it would be great to get a higher percentage of Hackage packages using simple, hosted continuous testing... I'd personally like to replace my Jenkins install if they can get the necessary GHC versions in there. Best, -Ryan
