Re: [ANNOUNCE] Glasgow Haskell Compiler 9.0.1-alpha1 released
Very late followup, but I just wanted to share that Fedora users can install this now (stable since last week) with: sudo dnf module install ghc:9.0/default Thanks, Jens ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/glasgow-haskell-users

There have been several false-starts on this ticket and while the solution we are ending up with is indeed a compromise (in both performance impact and convenience), I am fairly convinced it is the best we can do. I am waiting for a version of the patch to validate as we speak. As soon as it (and a few other relevant patches) have been backported I will move ahead with cutting the release candidate. I hope this can happen by the end of the week.

Re: [ANNOUNCE] Glasgow Haskell Compiler 9.0.1-alpha1 released
Will this be updated to the latest containers before release? It's two versions behind at the moment.
