 # [unreleased]
 
+## Fixed
+
+- Fixed transition for dual power lane assemblies: When going from dual side submode to single side
+  submode, perform logical commanding first, similarly to when going to OFF mode.
+
 ## Changed
 
+- Bugfixes for STR mode transitions: Booting to mode ON with submode FIRMWARE now works properly.
+  Furthermore, the submode in the NORMAL mode now should be 0 instead of some ON mode submode.
+- Updated GYR bias values to newest measurements. This also corrects the ADIS values to always
+  consit of just one digit.
 - The CCSDS IP core handler now exposes a parameter to enable the priority select mode
   for the PTME core. This mode prioritizes virtual channels with a lower index, so for example
   the virtual channel (VC0) will have the highest priority, while VC3 will have the lowestg
-  priority. This mode will be enabled by default for now, but can be set via the parameter IF with the unique
-  parameter ID 0. The update of this mode requires a PTME reset. Therefore, it will only be performed
-  when the transmitter is off to avoid weird bugs.
