KES 4.0.0 now adds full mbin compatibility
KES is the Kbin Enhancement Suite.
This is just an update to note that the tool has undergone a total quality audit to ensure that all of its add-ons support both kbin and mbin instances and behave in an expected fashion regardless of which instance type you are using.
If you had previously tried KES on an mbin-type instance and encountered anomalous behavior, you should now find that it has full compatibility.
