Looking to get back into it

Hey everyone, I played years ago I think and haven't played since. I saw it released or came outta early access I think recently and wanted to get back into it. I enjoyed it when I first played, I played it solo or not in a PVP world (I think it was PVE? If that's a thing) and I enjoyed it but it got a little stale quick as there wasn't to much to do. Could anyone explain any big changes or things to do in the past 2 ish years? It doesn't have to be everything but just the major things. Any tips/tricks would be great, thanks!
