v2.2.0

• Changes
  • Added snooze support to turn off reboots for 15 minutes per snooze. This is
    super helpful for debugging issues that interact with device health checks.
    It's activated via either a USR1 signal or the "snooze" command.
  • Support an initial grace period to avoid hardware watchdog reboots shortly
    after starting up. This lets you ensure that devices are up for a short
    period of time to make them debuggable. This helps with remote devices that
    may not connect to the network quickly enough to be easily debugged.
  • Support 2 second hardware watchdog timeouts. Previously the limit was 5
    seconds. 2 seconds is the shortest possible since the pet timer resolution
    is in seconds.
