Release Notes
---------------------------------------------------------------------------------------------------------
- Increase PWM frequency of Aux output from 2kHz to ~16kHz, in order to decrease the noise (whine) when 
  the Aux output is used to drive small motors. 
- Fix a bug that caused the engine to automatically start on boot when used with the Benedini TBS Mini 
  sound card (as opposed to waiting for the explicit command to start from the user). This bug was found 
  to have been introduced on 8/12/2017 with v0.92.10 firmware.
