Spigot (the server software out server uses) was updated to 1.17 late last night. Now I’m just waiting on plugins to be brought up to date. As soon as that’s done, I’ll update the server to 1.17.
I’ve been asked if there will be a world reset for 1.17, not for part one. When Caves and Cliffs part two comes out later this year, that will necessitate a world reset.
