Upstream has added the equivalent of our SentientNPC API, with exception to the EnderDragon. We've added Mob to the EnderDragon, and our SentientNPC API should behave the same. Vex#getOwner has been deprecated and a replacement Vex#getSummoner has been added using Mob. However, since 1.13 is not production ready, SentientNPC API is subject for removal in 1.13.1 since 1.13 API is not compatible with 1.12. Please move to the Mob interface ASAP. This update has not been tested by PaperMC and as with ANY update, please do your own testing Bukkit Changes: c5ab54d8 Expand GameRule API ab9a606c Improve entity hierarchy by adding Mob interface.
