This page lists the protocol version numbers used in the various MC releases. Official releases are marked bold, weekly snapshots are in regular font.

The 1.7 release has seen a complete rewrite of the network protocol (using Netty), including the version numbers. The protocol numbers have been reset. This page contains version numbers for both the pre-Netty and post-Netty protocol versions.

A list of packet IDs and names per linked protocol version on this page is available here.

Versions after the Netty rewrite

Beginning with the 1.7.1 pre-release (and release 1.7.2), versioning was reset.

Notes

  1. ↑ Although it has the same ID as 1.9.1, the April Fools version 1.RV-Pre1 has new blocks and items that cannot be used on 1.9.1 servers.
  2. ↑ <Dinnerbone> Protocol itself didn't change in 31c btw, but we added an entity which warrants incompatibility
  3. ↑ Despite having the same ID, 13w41a and 13w41b are incompatible.

Versions before the Netty rewrite

Minecraft version 1.6.4 and older used a protocol versioning scheme separate from the current one. As such, the same version number may ambiguously refer to an old version in this list and a new version in the list above.

Notes

  1. ↑ This protocol has no encryption and a different handshake layout than the previous ones.
  2. ↑ This version is incompatible with 12w01a which also uses protocol 23, due to the removal of 0x1B.
  3. ↑ These versions are incompatible with the previous snapshots also using protocol 22, due to the additon of 0xFA Plugin Message.
  4. ↑ This version was never publicly released, but is found lurking on the old update site. It's equivalent to beta 1.6 in terms of protocol. Curiously, it has a unique protocol version.
  5. ↑ 1.0.15 is the first version publicly supporting SMP
  6. ↑ These versions have a multiplayer button, but a specific server is hardcoded.
  7. ↑ These versions (specifically 1.0.8_01, 1.0.7 and 1.0.5_01) have multiplayer code, but no multiplayer interface.
