@@ -22,11 +22,15 @@ will consitute of a breaking change warranting a new major release:
 
 - Version of thermal controller which performs basic control tasks.
 - PCDU handler can now command switch of the 3V3 stack (switch ID 19)
+- Set STR dev to OFF in assembly when it is faulty.
+- STR: Reset data link layer and flush RX for regular commands and before performing special
+  commands to ensure consistent start state
 
 ## Fixed
 
 - PTME was not reset after configuration changes.
 - GPS health devices: ACS board assembly not reacts to health changes.
+- STR COM helper: Reset reply size after returning a reply
 
 ## Changed
