RMenu 3.0.1 is now out, which mainly adds RMenu 4 | X21 support into AquaRunner, as well as adding BatchLoad support.

If you already have RMenu 3 and would like to try running RMenu 4 | X21 in AquaRunner or you would like to use RMenu 3 alongside BatchLoad, then you should probably update to RMenu 3.0.1.
