-- Refactored IMTQ handlers to also perform low level I2C communication tasks in separate threads.
+- Refactored IMTQ handlers to also perform low level I2C communication tasks in separate thread.
   This avoids the various delays needed for I2C communication with that device inside the ACS PST.
   (e.g. 1 ms delay between each transfer, or 10 ms integration delay for MGM measurements).
 - Updated generated CSV files: Support for skip directive and explicit
   "No description" info string
+- The polling threads for actuator polling now have a slightly higher priority than the ACS PST
