 ## Using multi-root workspaces
 
 First, check out [what multi-root workspaces](https://code.visualstudio.com/docs/editor/multi-root-workspaces) are. The idea of using multi-root workspaces, is to be able to work on several different Haskell projects, where the GHC version or stackage LTS could differ, and have it work smoothly.

 Now make sure to remove cached/installed libraries to avoid getting segfaults at runtime.
 
 As a final workaround, you can try to compile HLS from source (the extension should pick it up) via ghcup, see [https://haskell-language-server.readthedocs.io/en/stable/installation.html#ghcup](https://haskell-language-server.readthedocs.io/en/stable/installation.html#ghcup). In any case, the recommended approach is to let GHCup install the GHC binaries.

 Sometimes there is a release (stable) and pre-release (unstable) at the same time and we need to do a release for the stable release and sometimes we need to do a release for the pre-release series.
 To simplify the release management, the following policy is in place:
 
-* The branch `master` contains the current pre-release

-  * Dependency version bumps are automatically performed by dependabot against `master`
