Hi Zubin,

Thank you for message!

With talk of retiring the 8.10 branch, I think it might be worthwhile to
remind folks that GHC 8.10(.6) is still the most recent release that is
suitable for production use.  GHC 9.0.1 is *not* suitable for production
use due to major issues, and GHC 9.0.2 is not ready yet.

Major GHC 9.0.1 issues:

* https://mail.haskell.org/pipermail/haskell-cafe/2021-March/133540.html
* https://gitlab.haskell.org/ghc/ghc/-/issues/19345
* https://gitlab.haskell.org/ghc/ghc/-/issues/19976

GHC 9.0.2 progress:

* https://gitlab.haskell.org/ghc/ghc/-/milestones/367

Thank you to the GHC developers for great progress.  Four active
branches does indeed sound daunting.  I hope that the GHC 8.10.7 release
goes well, and I am really looking forward to a production-ready release
of GHC 9 whenever it is ready!
