Minecraft 1.14.4 is finally released fixing again some major bugs and performance issues (Which some actually fixed this time!)
We highly recommend to upgrade to this version if your still using the older Minecraft 1.14.x vanilla versions.
EDIT: CraftBukkit Plugin support now released! (Spigot Craftbukkit can be installed from Plugins and Modpack section)
Update your servers now! For how to, see:
