For everything else, OgRiCanX’s community changelog breaks down all changes.

Before you update an existing world

This is not a drop-in update. The changelog lists a lot of changes that affect existing worlds, including items that disappear and builds that need rebuilding. You should absolutely read the Before you update page first, and always make a backup before switching versions. Other than the mentioned changes, updating is as easy as selecting the new version in the HypeServ Panel.
