@@ -24,6 +24,10 @@ will consitute of a breaking change warranting a new major release:
 - ACS Controller strategy is now actually written to the dataset for detumbling.
 - During detumble the fused rotation rate is now calculated.
 - Detumbling is now exited when its exit value is undercut and not its entry value.
+- Rotation rate of last cycle is now stored in all cases for the fused rotational rate
+  calculation.
+- Fused rotation rate estimation during eclipse can be disabled. This will also prevent
+  detumbling during eclipse, as no relevant rotational rate is available for now.
 - `EiveSystem`: Add a small delay between triggering an event for FDIR reboots and sending the
   command to the core controller.
