Hii! We would love to hear all your questions about Caves&Cliffs. It can be about certain features, about the split of the update or anything else you want to ask related to it :). Feel free to share your questions in a thread to this tweet. Thank you! 
Significant worldgen changes have traditionally been a "wipe save, start fresh" event. Old maps can probably be imported into the new height range, but given the significant worldgen changes coming up, will newly-genned chunks blend nicely into existing terrain?
