I'd like to recommend a mod called ViaFabric+, please add ViaFabric+ to Minecraft versions 1.8.9, 1.20.1, and potentially more. ViaFabric+ is a modification that provides a bridge between different Minecraft versions, enabling players to connect to a single server regardless of the version they are using. This is an incredibly helpful feature, as it allows players to enjoy the benefits of their favourite mods and plugins on a server that may otherwise be limited to a specific Minecraft version.
With ViaFabric+, players can join a server using their preferred Minecraft version, without worrying about compatibility issues. This means that players can use their favourite mods, tools, and features from any version of Minecraft on the server, making the gaming experience more enjoyable and personalized.
In addition, ViaFabric+ offers a range of other benefits. For example, it can help to reduce server lag, as players are distributed across different Minecraft versions, rather than all playing on a single version. It also enables server owners to attract a wider range of players, as they can advertise the server as being compatible with multiple Minecraft versions.
Overall, adding ViaFabric+ to your Minecraft client is a smart choice that can greatly enhance the gaming experience for all players.
ViaForge is just an alternative version that works the same but for Forge
