Supported versions

List of all supported Minecraft versions and server software

Client Versions

• Minecraft: Java Edition 1.7.2-26.2

• Minecraft: Bedrock Edition is handled through GeyserMC (skipped by default; see below)

Software

• Java 17 (or above)

Servers

• Velocity (3.6.0 or above)

• BungeeCord (1.20 or above)

• Paper (1.21 or above)

• Bukkit/Spigot (1.8.8 or above)

  • Bukkit and Spigot are supported, but it is highly recommended to use Paper.

Dependencies

• Netty 4.1 (or above)

  • If your server depends on an older Netty version (1.7.2-1.8.8 servers mainly have this problem), please consider using an updated fork such as PandaSpigot (or similar alternatives).

Disclaimer

• It is possible that some highly altered server forks are unsupported.

• Some significantly modified Minecraft clients (including cheats) may interfere with the verification process. Since it is the client developer's duty to guarantee vanilla protocol, this cannot be fixed by Sonar.

Sonar skips players connecting through GeyserMC by default, as the UDP protocol is deemed unstable, especially when compared to TCP, which Minecraft: Java Edition uses. You can, however, enable support for Bedrock in the configuration.
