Release checklist

[Mikolaj]

Last minute optional breaking changes:

• [ ] hlint (M-x haskell-check | hlint . | C-x `)
• [ ] remove dead code detected with weeder or HPC

Last minute optional checks and tweaks:

• [ ] compare current small benchmark results in CI vs CI benchmark logs from the previous release (but logs are kept only 90 days!)
• [ ] run long benchmarks and benchmarks against other libraries
• [ ] profile and optimize any surprise regressions and outliers
• [ ] spellcheck any longer texts
• [ ] verify that code samples in README and elsewhere make sense and match their counterparts in current tests
• [ ] add any used extensions to other-extensions in .cabal file

Testing:

• [ ] rebuild with -fwith_expensive_assertions
• [ ] run the full test suite (not the short CI one)
• [ ] review the output of CI for any red flags

Package:

• [ ] switch on the release flag in .cabal file
• [ ] check that haddocks get generated and fix any warnings
• [ ] update changelog
• [ ] if breaking changes, bump version number some more
• [ ] verify no dependencies are too strict
• [ ] cabal check; cabal sdist
• [ ] upload hackage candidates
• [ ] create a draft of the github release
• [ ] flesh out the github release, copy the changelog
• [ ] publish the github release, which also creates a tag
• [ ] publish hackage candidates as the official releases

Supervise:

• [ ] if the haddocs don't build, upload them
• [ ] https://matrix.hackage.haskell.org/package/horde-ad

Cool down:

• [ ] bump version number for development
• [ ] switch off release flag
