Today, Mojang has released Minecraft 1.13, the Update Aquatic! I know some of you might be anxious to try it, but you'll need to stay on 1.12.2 to connect to the Creeper's Lab for the time being.
Some of you are aware already that this new game version includes a lot of technical upgrades, many of which break internal compatibility. The Spigot team estimates that the amount of changes is about the equivalent of 1.9 to 1.12, combined. This means that a lot of server plugins will need a review and updates before we can safely look forward. We have to wait for some plugin developers to refresh their code, while I'll have to take care of some changes of my own. As such, it's likely that this will need some time. Your patience is appreciated!
Keep an eye on this space for later updates!
