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 allowes inheritance. A documentation about this file is here

Versions after the Netty rewrite

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

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).
