ViaVersionProtocolSupport

ViaVersionProtocolSupport adds compatibility for Minecraft versions 1.4.6–1.6.4, similar to what ProtocolSupport provided, and extends support to classic versions (c0.0.15–1.4.6), which ProtocolSupport did not cover.

Note: Fallback support is limited to versions 1.0.0–1.6.4 and may not work with ViaProxy unless Use-ViaLegacy is disabled.
