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.

Versions after the Netty rewrite
Beginning with the 1.7.1 pre-release (and release 1.7.2), versioning was reset.
Notes
- ↑ 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.
- ↑ <Dinnerbone> Protocol itself didn't change in 31c btw, but we added an entity which warrants incompatibility
- ↑ 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. 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).

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.

Notes
- ↑ This protocol has no encryption and a different handshake layout than the previous ones.
- ↑ This version is incompatible with 12w01a which also uses protocol 23, due to the removal of 0x1B.
- ↑ These versions are incompatible with the previous snapshots also using protocol 22, due to the additon of 0xFA Plugin Message.
- ↑ 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.
- ↑ Beta 1.5_02 was a server-only update.
- ↑ Alpha 1.2.3_05 is actually the first release of Alpha 1.2.4.
- ↑ 1.0.15 is the first version publicly supporting SMP
- ↑ These versions have a multiplayer button, but a specific server is hardcoded.
- ↑ These versions have multiplayer code, but no multiplayer interface.
