The Haskell Platform wiki page says the platform follows a 6-month release schedule, yet the last release occurred more than one year ago, and I couldn't find information about future plans. Are there plans to update the platform with ghc 7.8.2? Thanks, Dominick

As far as I know, there are plans to release Haskell Platform shortly (no more than a few weeks) after GHC v7.8.3 is released. GHC v7.8.2 has a few showstopper bugs for some use cases that made it unsuitable for a platform release. The infrastructure for maintaining Haskell Platform was all rewritten since the last release with the goal that it should be much easier to keep it on schedule in the future. Alpha builds should be available very shortly after GHC v7.8.3 is released. On Mon, Jul 7, 2014 at 9:21 PM, Dominick Samperi wrote:

The Platform keeps getting stuck waiting for GHC. The skipped release was because ghc 7.8 took some 6 months after "we plan to release just before ICFP 2013"(!); now it's waiting on ghc 7.8.3 bug fixes, which were "should be released by the end of the week" a couple of weeks ago. :( 7.8.3's bug fixes are significant enough that it would be bad to release a platform without them. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net

And we couldn't go with 7.6 because of some problems on newer OS X:es right?

Among other things, yes (ghc 7.6 needs to be patched to work with Xcode 5). 7.8 is supposed to improve some things on Windows as well; plus it'd be nice to have 7.8's improvements in general. But the OS X issues are the biggest user-facing ones, and come up pretty much every time someone tries to install the current Platform on OS X. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net

Yup! Heck, one of the patches merged into 7.8.3 also makes it easy for a single ghc build to work on the full range of 10.7-10.10, which is pretty darn awesome. On Tuesday, July 8, 2014, Brandon Allbery wrote:

Releasing two platforms with the same GHC version is a recipe for disaster as well. It's currently designed to cohabitate with other versions of the platform and that is dependent on each platform release having a unique GHC release.

This sounds like something we need to fix, or we can't make HP releases more often than GHC releases, which could mean >1 year between HP releases (i.e. which is the case with 7.8 I think).

Probably not going to happen any time soon, cabal would need to know what version of the platform is installed, if any, to get the ~/.ghc stuff correct to prevent them from trying to use the same package database.

Haskell Platform 2014.2.0.0, based on GHC 7.8.3 just went alpha! I expect the platform team to run it through its paces and hope that we'll have no barrier to a release within two weeks at most - perhaps much sooner! If you want to be intrepid and try it - head to to the haskell-platform mailing list and look for announcements. As for versioning: The situation is that we can't (on Mac OS X at least) install two versions of Platform at the same time with the same GHC release. For patch release, 2014.2.0.0 and 2014.2.x.y this is fine and probably what we want: If we update a patch release, we sort of want people to use that, and not use the earlier vesion anymore. 2014.4.0.0 will need a new version of GHC... or will else we'll live with the idea that it isn't installable at the same time as 2014.2.0.0. - Mark
