   the active SD card is switched or there is a transition from hot redundant to cold redundant mode.
   This gives other tasks some time to register the SD cards being unusable, and therefore provides
   a way for them to perform any re-initialization tasks necessary after SD card switches.
+- TCS controller now only has an OFF mode and an ON mode
 - The TCS controller pauses operations related to the TCS board assembly (reading sensors and 
   the primary control loop) while a TCS board recovery is on-going.
-
-## Changed
-
 - Allow specifying custom OBSW update filename. This allowed keeping a cleaner file structure
   where each update has a name including the version
 - The files extracted during an update process are deleted after the update was performed to keep
   the update directory cleaner.
 
+## Added
+
+- TCS controller: SUBMODE_NO_HEATER_CTRL (1) added for ON mode. If this submode is
+  commanded, all heaters will be switched off and then no further heater
+  commanding will be done.
+- Fixed a bug in persistent TM store, where the active file was not reset of SD card switches.
+  SD card switch from 0 to 1 and vice-versa works without errors from persistent TM stores now.
