v0.13.4

• Changes
  • Fixed new compiler warnings with Elixir 1.15
  • Support the Nerves Heart v2.2 snooze feature.
    Nerves.Runtime.Heart.snooze/0 will request that heart continues to pet
    the hardware watchdog and ignore lack of updates from Erlang for a short
    amount of time to allow debug of conditions that would otherwise be
    interrupted by a watchdog timeout.
  • Report errors from Heart functions rather than hang forever when Erlang
    :heart is unresponsive.
  • Support additional status from Nerves Heart v2.2 to report the initial
    bootup grace period timeout and snooze timeout remaining.
