Hub Firmware Release Notes - 18.18

The release currently going out is a very targeted bug fix to prevent the hub from going offline for extended periods of time. For people with embedded background - the Hub has a built-in watchdog timer in case critical processes fail. We discovered a path that could cause a segfault of our main application and would therefore cause a watchdog and a reboot. Between the watchdog time and reboot time, it was possible to get up to 15 minutes of offline time.
