2011-9-29

  • Beta 1.9 pre2.
  • Protocol version is now 19
  • Four packets changed:
  • The 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
  • The format of the NBT is as follows

 COMPOUND
   LIST: 'ench'
     SHORT: 'id'
     SHORT: 'lvl'
   END
 END
