This is the expected new behavior in cabal 2.0, due to usage of Hackage Security. The new tarball is much larger since it keeps all revisions of a cabal file from all time (though I'm honestly surprised to hear it's 4 times the size). The additional files have to do with new features in Hackage Security, like mirroring and incremental updates. On Thu, Aug 17, 2017 at 10:35 AM, Jonathon Delgado wrote:
