Minecraft Network Protocol Docs 10/1/20

For 16u1-beta-9, (rc0), Network Protocol Version 417

Packet Changes

We're partway into implementing a server authoritative movement correction system that is currently turned off because it still has some outstanding bugs but the fields are still being sent across the wire; for now they're okay to ignore when incoming and it's fine to send a 0 when outgoing.

AvailableActorIdentifiersPacket

ActorInfo compound tags no longer contain an experimental flag.

New Packets

ItemComponentPacket

An array of the items with their components. It should be fine to send an empty array after the StartGamePacket.
