This plugin is a compatibility layer that will translate the Eaglercraft 1.5 packets to an EaglercraftX 1.8 connection, allowing them to connect to a 1.8-compatible Eaglercraft server. This usually involves running ViaVersion, ViaBackwards, and ViaRewind on your server as well, to upgrade the 1.8 connection to whatever modern version of Spigot you're running.

Note: If you would like to support versions of Eaglercraft 1.5 older than 22w34a (before singleplayer), add the -Deaglerxrewind.oldChunkFormat=true system property to your JVM arguments. This will perform worse for both clients and the server, but will be compatible with every version of 1.5 going back to 2020.
