Merge remote-tracking branch 'origin/develop' into continue_tcs_tests

CHANGELOG.md

@@ -24,13 +24,23 @@ will consitute of a breaking change warranting a new major release:
 
 ## Changed
 
+- Added additional logic for SDC state machine so that the SD cards are marked unusable when
+  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
+- 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.
