PaperMC/patches/server/1044-Brigadier-based-command-API.patch
Spottedleaf 66cb880754 Remove ThreadedWorldUpgrader patch 
The patch does not implement Vanilla forceUpgrade behavior.
Specifically, poi/entity conversion and regionfile recreation.

The Vanilla force upgrader is also no longer broken by CB, so the
bug fixes from this patch are not relevant anymore.
