At CMU I got to ride herd on a rather astonishing collection of ancient hardware; I wouldn't be looking to install ghc8 on much of it either, since usually upgrading the OS is no-go and I'd have to backport a lot of stuff to get it --- and, even more so, packages using it --- to build at all.

It's that time again. I'd very much like to drop containers support for GHC version 7.0 (so I can increase the lower bound on array to 0.4 for Safe Haskell-related reasons). I'd also prefer to drop support for GHC versions 7.2 and 7.4, but I'm somewhat open to being convinced not to. What do you all think?

I am still mainly using GHC-7.4.2.

I'm rather curious why! _______________________________________________ Haskell-Cafe mailing list To (un)subscribe, modify options or view archives go to: http://mail.haskell.org/cgi-bin/mailman/listinfo/haskell-cafe Only members subscribed via the mailman list are allowed to post.

That’s fair enough but couldn’t you just keep using an older version of `containers` on this hardware? Obviously, newer versions will contain bugfixes and new features but the same can be said for new releases of GHC (and probably a ton of other software on those systems) and missing out on those is apparently not a deal-breaker either.

How would you feel about switching to 7.6.3? That would definitely make my life easier. I have to warn you, however, that we will not support 7.6 or 7.8 forever. We'll probably drop 7.6 in another year or two, and 7.8 in another two or three. On Mar 9, 2018 11:15 AM, "Henning Thielemann" wrote:

GHC-7.8.4 is the last compiler that prevents me from "length (1,2)" but it has a bug in the optimizer that leads to a compiler crash. So I have the choice between GHC-7.6.3 and GHC-7.4.2. _______________________________________________ Haskell-Cafe mailing list To (un)subscribe, modify options or view archives go to: http://mail.haskell.org/cgi-bin/mailman/listinfo/haskell-cafe Only members subscribed via the mailman list are allowed to post.
