@@ -27,6 +27,8 @@ will consitute of a breaking change warranting a new major release:
 - Skyview dataset for more GPS TM has been added
 - The MGM and SUS vectors being too close together does not prevent the usage of the safe
   mode controller anymore.
+- Parameter to disable usage of MGM4, which is part of the MTQ and therefore cannot be
+  disabled without disabling the MTQ itself.
 
 ## Fixed
