The HLS team is proud to announce a new release for the vscode-haskell extension.
This is the first release which enables Language Server support for .cabal files by default.
If this causes any problem for you, you can disable the support for .cabal file by setting the new option "haskell.supportCabalFiles": "disable".
By default, this setting is set to automatic, which enables Language Server support for .cabal files conditionally on the version of your Haskell Language Server binary (HLS binaries older than 1.9.0.0 cannot process .cabal files).
