Release 3.3.0

This reads a little confusingly. I know it's best to use the present tense in commit messages, but I read this like a command as an end-user, i.e. I should update to vCloud Core 0.7.0 if I install vCloud Walker version 3.3.0.

Perhaps 'Dependency on vCloud Core upgraded to version 0.7.0' might be clearer?
