Alternatives to this mod:

• ClientViaVersion: This discontinued client-side plugin for The 5zig Mod implemented ViaVersion, ViaBackwards and ViaRewind for 1.7.10, 1.8.9, 1.12 and 1.12.2 clients, allowing them to connect to 1.7-1.12.2 servers. It also had a protocol translation for 1.7 servers, which there's an updated version at https://github.com/KennyTV/ViaVersion/tree/hack (unsupported).
• multiconnect: This client-side Fabric mod does also translate older protocols and fixes some differences between versions, which ViaFabric doesn't. Currently, it goes down to 1.10. (2020-06-23)
• Protocol4: This LiteLoader client-side mod allows your 1.7.10 client to connect to 1.7.x servers.
• ProtocolSupport: This Bukkit plugin allows clients to connect from older versions (down to 1.4.7).
• ViaVersion: ViaVersion can run as a plugin for BungeeCord, CraftBukkit, SpongeCommon and Velocity servers.
