Make a revision on hackage to support GHC 9.0

[andreasabel]

GHC 9.0 was released. lifted-async does not build because of the constraint on base.
I successfully tried:

cabal install --allow-newer lifted-async

I suggest to make a revision on hackage (https://hackage.haskell.org/package/lifted-async/maintain) that lifts the necessary upper bounds to allow compilation with GHC 9.0.

UPDATE:

• Blocked by hashable 1.3 does not install on ghc 9.0.1 haskell-unordered-containers/hashable#193.

Thanks for reporting.

I'm waiting for a dependency to be updated. The constraints package cannot build with 9.0.1 because the hashable package needs to be revised.

I successfully tested building lifted-async-0.10.1.2 just now with a relaxed upper bound on base (see below [1]).

So a new release does not seem necessary, just a revision of metadata on hackage.

E.g. here is my workflow for revisions: https://github.com/haskell-pkg-janitors/haskell-src/blob/540fc48dc2f0f2c75699315df950ff26e1918270/CONTRIBUTING.md

But it seems you are also planning to fix some warnings in #33, so this is of course not suitable for a revision...

Sorry for the delay. Just uploaded https://hackage.haskell.org/package/lifted-async-0.10.1.3.

Excellent, thank you! Works for me.
