Revision as of 17:47, 11 November 2011
This page documents the changes from the last stable Minecraft release (currently 1.8.1) to the current pre-release (currently 1.9pre4)
Contents
New packets
Enchant Item (0x6C)
Client to Server only
| Packet ID | Field Name | Field Type | Example | Notes |
|---|---|---|---|---|
| 0x6C | Window ID | byte | 1 | The ID sent by 0x64 |
| Enchantment | byte | 0 | The position of the enchantment on the enchantment table window, starting with 0 as the topmost one. | |
| Total Size: | 3 bytes | |||
Changed packets
"Slot" type change
Four packets changed:
- 0x0F player block placement
- 0x66 window click
- 0x67 set slot
- 0x68 window items
- 0x6B Create Inventory
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
Experience (0x2B)
Now float, short, short
Other changes
Protocol version is 20, as of 1.9pre4
New mobs: Blaze, Magma Cube, Ender Dragon, Snowman, Villager
Notchian server features two new protocols: RCON (server class: o.java) and Query (server class: su.java)
