we're skipping things that require a release branch to win some us time to merge some remaining PRs before the cut. E.g. C.2.

Currently at C.3.

Adding GHC 9.14 to CI (C.3.3) isn't easily possible yet because there's not even an official branch, there's a wip-branch in https://gitlab.haskell.org/ghc/ghc/-/merge_requests/14404 Same issue with bootstrap, c.3.5.

I propose to try finishing C.3 as much as possible without C.3.3 and add the remaining items on the checklist in OP.

[ulysses4ever]

I added a "PRs of interest" section in the OP where I list PRs that would be good to get into 3.16. Not all of that may happen but it's good to have a target. I used the 3.16 Milestone to collect those.

[geekosaur]

So we have two meta issues that are worked around for the time being but should be resolved properly for 3.18 if we can't get them figured out in time for 3.16:

• splitmix-0.1.3 references a symbol on Macs that GitHub's runners say doesn't exist
• the custom Setup for cabal-testsuite doesn't work with 3.14.1.1 and needs to be modified as per Make Cabal agnostic about working directory #9718

I've pinged the relevant people about both.

Tags pushed, candidates published

[ulysses4ever]

Will have to redo tags and candidates because of the missed copyright years updates, see #11061

[geekosaur]

Redone.

Release happened. Here's a discourse post: https://discourse.haskell.org/t/12544

Sadly, there's a big problem with it right off the bat: HLS won't be available. See #11101
