Modloader Updated to use 26.1 as the base. The existing modmenu example should still work. The mods can carry between game versions and will not break when using the osirus mod loader. So long as the update does not remove code the/a mod uses, it/they will continue to work and this is proof! Yay.
Update:
Major game version - 26.1
Updated link for classgraph dependency, should grab without issue now from maven.
