The 3.x branch is discontinued and obsolete. I think, you won’t find any download for 3.3.x anymore (well, maybe still on some servers…). Only 3.4.1 can be downloaded as a legacy build. Thus, consider upgrading to 3.4.1 (if you prefer a conservative approach) or to 4.0 (currently supported version).
