A protocol version number[1] (PVN) is an integer used to check for incompatibilities between server versions.

Usage[]

파일:Outdated client.png

An outdated client attempting to connect to a server on a a newer version.

Client and server versions with the same protocol version are compatible with each other. For example, a client running Java Edition 1.8.9 can connect to a server running Java Edition 1.8, as both have a protocol version of 47.

Upon attempting to join a multiplayer server, the game will check if the client has a protocol version newer or older than the selected server; if it does, the game will then alert the player that their client (or the server) is outdated.

Versioning[]

All versions, including minor releases and development versions on both Java and Bedrock editions, have their own protocol version. The version takes the form of an ever-increasing positive integer unlike client versions. Protocol versions may occasionally be skipped between major releases.

Storage location[]

Each Minecraft build since 18w47b specifies its current protocol version in the version.json file, found in the root directory of the client and server jars.

  • version.json
    •  protocol_version: The protocol version of this build.

List of protocol versions[]

자바 에디션의 최신 버전인 1.17.1의 프로토콜 버전은 Pending이다. 자바 에디션의 최신 개발 버전인 21w38a의 프로토콜 버전은 Pending이다.
