multiconnect
Multiconnect lets a client running the newest supported Minecraft version join servers that run several older releases.
What it does
The mod works by translating the network protocol and fixing gameplay differences between versions on the client itself. Because the fixes live in the client, a server cannot resolve these differences on its own, which is why the client side matters. Multiconnect is the only mod in this group that restores the swimming mechanics and parkour differences of earlier releases, and it also re-adds features removed from the client, such as command syntax.
Multiconnect is open source under the MIT License and is published for Fabric and Quilt. Its client-side environment means servers need nothing installed, and players need Fabric Loader to run it. Files exist for 1.17.1, 1.18, 1.18.1, 1.19, 1.19.1, 1.19.2 and 1.19.3, with 1.6-beta.26 as the latest file for both loaders, released 2023-02-23.
Key features
Multi-version connections
A client on the latest supported version can join servers running older Minecraft releases without switching installations.
Swimming and parkour restored
The swimming mechanics and parkour differences of earlier releases are restored, which other connection mods do not address.
Removed command syntax
Command syntax removed from the client in newer versions is re-added so older-server commands still work.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
How it compares
ViaFabric and ViaVersion are both open source Fabric mods that work on the client or the server, with a range of 1.8.9 – 26.3, and both serve more versions than Multiconnect does. ViaBackwards is open source under the GNU General Public License v3.0 only, covering 1.10 – 26.3 on Fabric and usable on either side. Multiconnect runs on the client alone and fixes version differences there, which is a different approach from these server-capable mods.
