 - Internal error reporter set is now enabled by default and generated every 120 seconds.
 - Persistent TM store dumps are now performed in chronological order.
+- Various robustness improvements for the heater handler. The heater handler will now only
+  process the command queue if it is not busy with switch commanding which reduces the amount
+  of possible bugs.
+- The heater handler is only able to process messages stricly sequentially now but is scheduled
+  twice in a 0.5 second slot so something like a consecutive heater ON or OFF command can still
+  be handled relatively quickly.
