 ## Changed
 
+- TCS: Remove OBC IF board thermal module, which is exactly identical to OBC module and therefore
+  obsolete.
 - Swapped PL and PS I2C, BPX battery and MGT are connected to PS I2C now for firmware versions
   equal or above v4. However, this software version is compatible to both v3 and v4 of the firmware.
 - The firmware version variables are global statics inititalized early during the program
@@ -40,6 +42,8 @@ will consitute of a breaking change warranting a new major release:
 - 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.
+- TCS CTRL: Limit number of heater handler messages sent in case there are not sensors available
+  anymore.
