Protocol version numbers

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. The json is minified and allows inheritance. A documentation about this file is here. You can also find protocol version in page of each development version in Minecraft Wiki

  Notes

  1. ↑ April fools snapshot.
  2. ↑ 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.
  3. ↑Protocol itself didn't change in 31c btw, but we added an entity which warrants incompatibility
  4. ↑ Despite having the same ID, 13w41a and 13w41b are incompatible.

  Examples

  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. For ease of navigation, this list is also split by Minecraft release stages, but the versions were not reset between these (other than near the start of alpha).

  Note: the position of alpha servers with relation to clients is mostly guesswork partially based on timestamps, and shouldn't be treated as an exact record of when things were released publicly.
