This update has not been tested by PaperMC and as with ANY update, please do your own testing
Bukkit Changes:
b999860d SPIGOT-2304: Add LootGenerateEvent
CraftBukkit Changes:
77fd87e4 SPIGOT-2304: Implement LootGenerateEvent
a1a705ee SPIGOT-5566: Doused campfires & fires should call EntityChangeBlockEvent
41712edd SPIGOT-5707: PersistentDataHolder not Persistent on API dropped Item
This is how it use to behave on Paper, and this is totally destroying
the ability to try to shut the server down gracefully during the
shutdown process as events firing on the watchdog thread are throwing
errors.
This isn't an issue on Spigot
This has caused me so many rollbacks on watchdog already :(
