Supported Client Versions (ViaVersion and ViaBackwards) Guide
ViaVersion and ViaBackwards translate supported Java Edition protocols between the client and the server. Together they let 1MoreBlock accept a wider range of Minecraft Java versions than the server’s native Paper version alone.
Commands and features on 1MoreBlock depend on the current server configuration, world, and your permissions. A command listed here may be limited to certain ranks or contexts.
What it adds
Section titled “What it adds”- ViaVersion protocol translation for newer-client/older-server combinations and shared protocol infrastructure.
- ViaBackwards translation that lets supported older Java clients join newer servers.
- Per-version connection diagnostics and compatibility handling.
- A wider connection window without changing the server’s actual gameplay version.
Commands
Section titled “Commands”This feature does not require a general player command. It appears automatically, through another menu, or through staff-created content.
Getting started
Section titled “Getting started”- Use a client version listed as supported by 1MoreBlock.
- Connect to the normal Java server address.
- For problems, report the exact client version, loader/modpack, and disconnect text.
Player notes
Section titled “Player notes”- Protocol support does not backport every visual, UI, item, sound, or gameplay feature perfectly.
- The server still runs one native Minecraft/Paper version.
- Bedrock clients use Geyser/floodgate, documented separately.
