Downgrading
Sometimes, you might want to return to an earlier version of Tidal. Use the ghc-pkg command to do so. Enter the following commands in your terminal (or Powershell for Windows users) to downgrade your Tidal installation.
Listing all the currently installed versions
This command will list the versions of Tidal you have installed. If there is more than one, the most recent will be used:
ghc-pkg list tidal
Uninstalling a version
To uninstall a version, you can do, for example:
ghc-pkg unregister tidal-1.0.6
Do this for each version until the most recent is the one you want.
Choosing a specific version
If you don't have the one you want installed, you can select the desired version:
cabal install tidal-0.9.10
