After an epic all nighter we have managed to port all of the features of the new V5 functionality to run in V4+! The whole back end looks just like the newer V5 backend....
When ever the version number is rendered out it will show V5 so that clients will not ask you to install the latest version on a website that as "its just an upgrade right"?
Install, relax and get on with learning V5 :)
