Up to now 'upgrade' took no args and tried to upgrade all installed packages to the latest versions. It retains that mode but also has a new mode rather like 'cabal install'. The difference is that with $ cabal install foo it means install latest version of foo but otherwise prefer the installed versions of deps of foo, while $ cabal upgrade foo means install the latest version of foo and also the latest versions of all the dependencies of foo.
