Unity 3.5 released, been using beta, do I need to do anything

So, I’ve been using the Unity 3.5 beta and now I see the official version has been released. Are there changes between the beta and the final version and should I be installing the new version over the existing one or deleting the existing one and installing fresh?

Thanks.

Just download the new version and install it. It will overwrite the older version and leave your projects intact.
