We are moving along with a planned update to LCO. The 1.13 version (or "aquatic update") has been started on a dev server for the purpose of testing plugins for compatibility. Once we have a stable and usable server ready for player use we will be moving it over.
Moving forward, one change that we have decided on is that we will not be returning with the Epic Generator plugins (World, Nether). While they are certainly visually interesting, they just pull the experience too far from the fundamental Minecraft game. If you are a fan of the Epics, I encourage you to spend some time on the 1.12 server while it is still up.
