This update has not been tested by PaperMC and as with ANY update, please do your own testing

CraftBukkit Changes:
1ec1b05e SPIGOT-5245: Unneeded cast to WorldNBTStorage in CraftWorld#getWorldFolder
e5e8eec2 SPIGOT-5241: setAttributeModifiers does not work on untouched stack
803eaa31 SPIGOT-5231: ShotAtAngle API for Fireworks
7881d2ae SPIGOT-5237: Horses, pigs do not drop their inventory

8887c5f4 Remove redundant late-bind option
dac29063 Rebuild patches

* Preserve old flush on save flag for reliable regionfiles

Originally this patch was in paper

* Fix some issues with the death event

- Entities potentially entering a glitched state to the client where
they appear to be falling over
- Donkeys losing their chest if the event was cancelled (only an
issue since the upstream merge)
- Some wither death logic running for an entity killed by a wither
