Cabal is allowed to use any version that fullfills the required bounds. It uses a heuristic the tends to prefer
* installed * newest * other in that order. If you want to make sure the newest version is used temporarily you can pass --constraint="foo-1.2.3.4" to cabal install. If you want to make this change more permanent you can set an exact version in a cabal.config file in the same directory as the .cabal file.
