Hi all, We're close to a new release of Cabal/cabal-install and I'd appreciate some help in testing the new release. To install the release candidate, simply run: cabal install http://johantibell.com/files/Cabal-1.18.0.tar.gz http://johantibell.com/files/cabal-install-1.18.0.tar.gz Please try on different OSes if you have several available. Report bugs at https://github.com/haskell/cabal/issues *Things to try* This is not a complete list of new features (and bugs fixed)! *Sandboxing* Sandboxes help prevent "dependency hell" by having each project you're working on use a separate package database to install its dependencies in. Try it out on one of your projects like so: cd my-pkg cabal sandbox init # only once cabal install --only-dependencies cabal configure cabal build *GHCi support* The new cabal repl commands lets you load up your library inside GHCi without lots of command line fiddling. Just run cabal repl instead of cabal build and play around without your library. *Known issues to be fixed before release* https://github.com/haskell/cabal/issues/1439 Cheers, Johan
