ViaFabricPlus

Fabric mod to connect to EVERY Minecraft server version (Release, Beta, Alpha, Classic, Snapshots, Bedrock) with QoL fixes to the gameplay

Why another protocol translator?

ViaFabricPlus is intended to replace multiconnect, and it also promises more compactness and stability. ViaFabricPlus can do everything multiconnect could do, but supports more Minecraft versions (listed below) and has more protocol changes implemented.

Supported Server versions

• Release (1.0.0 - 1.20.2 [23w32a])
• Beta (b1.0 - b1.8.1)
• Alpha (a1.0.15 - a1.2.6)
• Classic (c0.0.15 - c0.30 including CPE)
• Snapshots (3D Shareware, 20w14infinite, Combat Test 8C)
• Bedrock (1.20.0)
