Thank you and other contributors for your continuous work on this project. I’ve started using it recently, especially on an M1 macbook, and the experience has been good.

Great work as usual, thanks specially for the compile hls feature, i am just installing a custom version with

 ghcup compile hls --repository https://github.com/pepeiborra/ide.git --overwrite-version new-shake --cabal-project cabal-ghc901.project --git-ref reimplement-shake 9.0.1

I was able to upgrade with ghcup upgrade, but I don’t see 0.1.17 available for manual install here: https://downloads.haskell.org/~ghcup/.

The download server has a cache. It can be purged with e.g. curl. Try https://downloads.haskell.org/~ghcup/0.1.17/

That did the trick. Thank you!

I was also able to defeat the cache by appending a bogus query parameter, like https://downloads.haskell.org/~ghcup/?1.
