CHANGELOG.md

@@ -29,6 +29,10 @@ will consitute of a breaking change warranting a new major release:
 
 - TMP1075: Set dataset invalid on shutdown explicitely
 - Small fixes for TMP1075 FDIR: Use strange and missed reply counters.
+- TCS controller: A helper member to track the elapsed heater control cycles was not reset
+  properly, which could lead to switch transitions being completed immediately. This can
+  lead to weird bugs like heaters being commanded ON twice and can potentially lead to
+  other bugs.
 - TMP1075: Devices did not go to OFF mode when being set faulty.
 - Update PL PCDU 1 in TCS mode tree on the EM.
 - TMP1075: Possibly ignored health commands.
