Cabal for GHC 7.8

I noticed that the Cabal package doesn’t have a branch for ghc-7.8: http://git.haskell.org/packages/Cabal.git Is that intended? Maybe as a result the instructions at https://ghc.haskell.org/trac/ghc/wiki/Building/GettingTheSources to check out a branch from the *GitHub mirror repos* doesn’t work either. It fails with == running git submodule update Cloning into 'libraries/Cabal'... fatal: remote error: ghc/packages/Cabal is not a valid repository name Email support@github.com for help Clone of 'git@github.com:ghc/packages/Cabal.git' into submodule path 'libraries/Cabal' failed git failed: 256 at ./sync-all line 122.
