@@ -24,6 +24,8 @@ will consitute of a breaking change warranting a new major release:
   runtime now. This makes it possible to check the firmware version earlier.
 - The TCS controller will now always command heaters OFF when being blind for thermal
   components (no sensors available), irrespective of current switch state.
+- Make OBSW compatible to prospective FW version v5.0.0, where the Q7 I2C devices were
+  moved to a PL I2C block and the TMP sensor devices were moved to the PS I2C0.
 
 ## Fixed
