   the RADFET electronics.
 - The SD cards will still be switched OFF on a reboot, but this is done in a non-blocking manner
   now with a timeout of 10 seconds where the reboot will be performed in any case.
+- ACS Controller now includes the safe mode from FLP, which will calculate its rotational rate
+  from SUS and MGM measurements. To accommodate these changes, low-pass filters for SUS
+  measurements and rates as well as MGM measurements and rates are included. Usage of the new
+  controller as well as settings of the low-pass filters can be handled via parameter commands.
