Changed packets
"Slot" type change
Four packets changed:
This change affects the "slot" datatype. This type consists of at least a short (item_id). If this id isn't -1, a byte (count) and a short (uses) follow.
From 1.9pre2 onward, additional data is sent but only for certain item_ids. This means the protocol is no longer context free. The additional data is at least a short. If this short isn't -1, a byte[] array follows, containing gzipped NBT data
As of 1.9pre3, the format of the NBT is as follows
COMPOUND
LIST: 'ench'
SHORT: 'id'
SHORT: 'lvl'
END
END
