Forge and NeoForge ViaVersion have seen almost no use in recent months, aside from some very old client versions. Keeping the project updated and working has become increasingly time-consuming, and it’s no longer worth the effort.

Please consider switching to the FabricMC mod loader with one of our Fabric platforms, or use ViaProxy.

ViaForge

Client-side ViaVersion implementation for MinecraftForge and NeoForge

If you are using the latest Minecraft version and care about the gameplay being more enjoyable/functional, you may want to check ViaFabricPlus out.

• Minecraft 26.x+ versions
• 1.16.5 – 1.21.11
• 1.8.9 / 1.12.2 using the Forge or NeoForge (1.20.1+) Loader.

ViaForge supports sending a custom payload to transmit player protocol version data to the server. This allows servers to retrieve a player's protocol version via plugin messages, which can be useful for anti-cheat checks and version-dependent logic. For more details on how to use this feature, see the Server and Player Details Protocol wiki.

It cannot be guaranteed that this mod is allowed on specific servers as it can possibly cause problems with anti-cheat plugins.
(USE ONLY WITH CAUTION!)
