GHC Weekly News - 2015/06/10

Hi *,

Welcome for the latest entry in the GHC Weekly News. The past week, GHC HQ met up for a quick catch up on 7.10.2 (which you'll want to read up on, see below), and some other technical nonsense about some work we've been doing. As a result the current weekly notes have been slow - the current priority is the next release though, which leads us to...

7.10.2 status

7.10.2 is going to be out soon - our current plan is to have a release candidate on the weekend of Saturday the 13th, and the final release the next week. That means if you want something fixed, you'd better hollar very soon, or we're just not going to get to it!

If you're wondering what's currently been fixed/scheduled, the status page shows the current set of tickets we've fixed and plan on fixing.

List chatter

  • Jan Stolarek asks: in some cases, GHC will generate default instances or values, but that source code has no textual information location (for example, consider an instance clause without the where) - what do people think about fixing this, and are there anythings to look out for? https://mail.haskell.org/pipermail/ghc-devs/2015-June/009202.html
  • David Luposchainsky has opened a new thread - about moving fail out of Monad and into its own typeclass, MonadFail. This change is a request that's very long in the tooth (older than the AMP or FTP changes by a landslide), but David's proposal has a clearly set out goal to tackle compatibility, warnings, and implementation. https://mail.haskell.org/pipermail/ghc-devs/2015-June/009186.html
