New upcoming foraging update build question.

Since the new foraging update has blocks included in the new updates it is safe to presume that you would only be able to play the new island in the newer versions just how the beta has been. Does that also mean that you can acquire these new blocks and build on your own island with them. There is also a chance that skyblock in general will now be required to play on the new version, and in that case my question is useless. Any information or thoughts would be useful.
