Paper/Spigot-Server-Patches/0284-Mob-Pathfinding-API.patch
Aikar 64ed429884
(FIRST 1.16.3): Update Paper to 1.16.3
This is a pretty tiny update with very little changed. Recommended to update
from 1.16.2 ASAP as 1.16.2 is now no longer supported.

Plugins should mostly remain working as the NMS revision did not change.
