The Minecraft server has been updated to 1.17. Some plugins, such as Essentials, are not fully compatible. Dynmap should be working. There may be some jank here and there, including sleeping. Feel free to try it out. I will probably expand the game world a little bit once it’s determined to be stable enough.
I’ll update this post again as more updates to plugins, etc roll out. I’m also thinking of adding a portal to a resource world that can be used for gathering, and that will be wiped clean each time a new version comes out.
