This hasn't been 100% confirmed yet. But if you build on the unfinished biomes you could probably expect that to be destroyed.

Nope, but the world you have will "with a high chance" will not have things released post-update.
In case anything incompatibility-related happens, I suggest you to back up your world and then use "unofficial" releases of the game to play your older saves.

Modders will not allow this. You can already export buildings to individual schematic files and reroll prematurely explored regions.

As an EA game you should expect that nothing is final and that it is quite possible you will need to start over as stuff gets added and plans change.

Well, it's hard to say for sure since this is still pretty early in development but with any early access game it's also best to just accept that you will need to restart worlds a few times as major updates hit. Some change in ways were you can keep a legacy server but it simply won't have everything new available on it, or at least not available in already defined (explored) areas of that map. Others change in ways were legacy saves simply no longer function at all and you are forced to start new whether you want to or not. So far the updates we've gotten are that first category where you can keep your legacy server but may be lacking content in it, but there's no guarantee it will stay that way through all updates up until full release.

Tks all
