Next release, 0.8

[meooow25]

It's been a while since 0.7 and we've accumulated commits, should we start preparing for a release?

Pending things I'd like to see done/fixed for 0.8:

• Add filterKeys for Map and IntMap #972
• NFData1,NFData2 instances (#767) #992
• updateMax Map/IntMap discrepancy #1061
• foldl' and foldr' for Seq are not strict in the starting value #1072
• Improve Ord instances for IntSet and IntMap #470, Improve Ord IntSet instance #787
• IntSet foldl and foldr smell funny #666
• Inline the common case of balance functions #1056
• Fusible Set,Map fromAscList (working on it)
• Build Set and Map more efficiently and consistently #1042

It's expensive to bump major version of containers, hundreds and thousands of packages would have to update. Please consider sticking to 0.7.*.

There is an upcoming release of GHC 9.12 very shortly, do you aim to release containers before that? As with any boot library, clients hardly ever use a release unless it is bundled with GHC.

We have breaking changes so we do need a major version bump. The changes aren't drastic (at least in the public API), but they are still breaking changes.

GHC 9.12 is sticking to 0.7 (GHC #25123), which is fine.

Anyway, the release is not happening right now. This is just to get the ball rolling and track what we want to include, we can decide the time of release once these issues are resolved.

GHC 9.12 is sticking to 0.7

I'm not sure but i have the feeling they put that version number there because it was the latest version available. Perhaps it would be nice to have a new containers version together with a new major ghc versions because at that point several things have to be upgraded anyway. Though i can understand it would perhaps be too short notice. Would it go into ghc 9.14 then? or a point release of 9.12?

[treeowl]

I don't think a point release is likely to take a major release of containers. If we want to get a major release in, now is probably the last time.

[meooow25]

Yes, 0.8 should make it into 9.14.

Even if it's not too late for 9.12, I don't see a good reason to rush the release. A new major release means other core libraries also need to update to accept the new containers, which is a lot of work. Another thing I want to make sure is that we include all the breaking changes we want to at once, so we don't need another major release in the near future.
