That's really good news!
But if it displays 1.4.4, then it very probably still is. Cabal in general is not working well at the moment. A reliable fix is to remove all the packages by hand - on Mac OS and Linux you can do this by removing the hidden .cabal and .ghc folders from your home folder. Then install again using the 'old style' cabal commands which work much better than the new ones. You can do this with cabal v1-update then cabal v1-install tidal
So in brief I'm not sure why it's working now but wasn't before !
