Support for GHC 9.8.4

[meMuszr]

Hi -

I'm new to this whole environment so excuse me if I'm doing something incorrect.

HLS states supported versions here:
https://haskell-language-server.readthedocs.io/en/latest/support/ghc-version-support.html#current-ghc-version-support-status

Snapshots:
https://www.stackage.org/snapshots

LTS 23.8 uses GHC 9.8.4 which is not supported by HLS - is there a way to add support? I would imagine the minor version increment would make this easy but not sure how to go about it myself.

@meMuszr Thank you for the bug report!

HLS master already supports GHC 9.8.4, we are merely missing a release for GHC 9.8.4 which we are planning to do soon.
You can compile HLS from source via ghcup, for example ghcup compile hls --ghc 9.8.4 --git-ref master, that should work fine.

Thanks for the support. Is there a reason these don't release in tandem? Confusing DX trying to bootstrap a project with defaults and not having it work appropriately.

Is there a reason these don't release in tandem?

Basically, because they're maintained by separate groups of people, both somewhat lacking in manpower (ditto GHCup, Cabal...). It's a recognised problem and I believe there have been discussions around syncing releases up better, possibly shepherded by the Haskell Foundation, but I can't seem to find a thread about this right now.

Still waiting for this, what's the holdup for making a new release?

[fendor]

We were hoping we could coordinate it with the upcoming 9.6.7 and 9.12.2 release.

Support for GHC 9.8.4 will be added with #4434
