Pre-release protocol
This page documents the changes from the last stable Minecraft release (currently 1.13.2, protocol 404) to the current pre-release (currently 19w02a, protocol 452). Note that this page contains bleeding-edge information that may not be completely or correctly documented.
One who wishes to commandeer the merging of this into Protocol when an update is made must be sure to respect any changes that may have occurred to the respective packets there.

Data types
Position
64-bit value split in to three parts
- x: 26 MSBs
- z: 26
LSBsmiddle bits - y: 12
bits between themLSBs
Encoded as followed:
((x & 0x3FFFFFF) << 38) |((y & 0xFFF) << 26) | (z & 0x3FFFFFF)((z & 0x3FFFFFF) << 12) | (y & 0xFFF)
And decoded as:
val = read_unsigned_long(); x = val >> 38; y =(val >> 26) & 0xFFFval & 0xFFF; z =val << 38 >> 38(val << 38 >> 38) >> 12;
Note: The details of bit shifting are rather language dependent; the above may work in Java but probably won't in other languages without some tweaking. In particular, you will usually receive positive numbers even if the actual coordinates are negative. This can be fixed by adding something like the following:
if x >= 2^25 { x -= 2^26 } if y >= 2^11 { y -= 2^12 } if z >= 2^25 { z -= 2^26 }

Entity Metadata
Entity Metadata Format
Note that entity metadata is a totally distinct concept from block metadata. It is not required to send all metadata fields, or even any metadata fields, so long as the terminating entry is correctly sent.
Entity Metadata is an array of entries, each of which looks like the following:
Name | Type | Meaning |
---|---|---|
Index | Unsigned Byte | Unique index key determining the meaning of the following value, see the table below. If this is 0xff then the it is the end of the Entity Metadata array and no more is read.

|
Value | Optional value of Type | Only if Index is not 0xff : the value of the metadata field

Chunk Data
- Main article: Chunk Format
- See also: #Unload Chunk
The server only sends skylight information for chunk pillars in the Overworld, it's up to the client to know in which dimenison the player is currently located. You can also infer this information from the primary bitmask and the amount of uncompressed bytes sent. This packet also sends all block entities in the chunk (though sending them is not required; it is still legal to send them with Update Block Entity later).

Chunk Section structure
A Chunk Section is defined in terms of other data types. A Chunk Section consists of the following fields:
Field Name | Field Type | Notes |
---|---|---|
Block count | Short | Number of non-air blocks present in the chunk section, for lighting purposes. "Non-air" is defined as any block other than air, cave air, and void air (in particular, note that fluids such as water are still counted). |

Handshaking
Clientbound
There are no clientbound packets in the Handshaking state, since the protocol immediately switches to a different state after the client sends the first packet.
Serverbound
Handshake
This causes the server to switch into the target state.
