Which stable GHC release is expected to have support for linear types?

[Wolfgang Jeltsch]

Hi!

I am just reading the instructions for cloning GHC from Git under

    https://ghc.haskell.org/trac/ghc/wiki/Building/GettingTheSources#CloningfromGitHub

Do these instructions also apply in an analogous way to cloning your GHC
repository?

All the best,
Wolfgang
