Hi Mark,
I was planning on releasing GHC 7.8.3 very soon (in the next few days,) and I'm wondering if it is still a possible candidate for the next Haskell Platform?
Actually there are few commits of changes to Haddock which fix a rather serious hyperlinking bug but I'm not sure whether this is relevant. It's on the 7.8 branch already. Just piping up in case it matters.
To be clear, there are no library updates this time around - 7.8.3 is almost 100% a pure compiler/runtime bugfix release, and some of the fixes are quite bad.
https://ghc.haskell.org/trac/ghc/ticket/9078 https://ghc.haskell.org/trac/ghc/ticket/8768 https://ghc.haskell.org/trac/ghc/ticket/9148 https://ghc.haskell.org/trac/ghc/ticket/9001
The first one, #9078, would be particularly bad to let slip into the release - it affects possibly all EDSLs using mkStableName for sharing, and is very easy to trigger by allocating stable names quickly. I'd say #8768 is somewhat nasty as well. Accelerate and SBV are two examples of projects that will crash.
There are currently no plans to even bump the corresponding library numbers - we didn't do so for 7.8.2, and there are no changes at all that would warrant a bump for 7.8.3. It's really a stability release more than anything and irons out several real bumps.
Do let me know what you think - I'll keep this thread updated as the release gets closer if anything else goes in.
