v0.13.7

• Changes
  • Add Nerves.Runtime.Heart.guarded_immediate_reboot/0 to ungracefully reboot.
  • Modify Nerves.Runtime.FwupOps.factory_reset/1 to immediately reboot to
    avoid a graceful shutdown unintentionally partially undoing the factory
    reset work.
  • Default EXT4 application partitions to remount read-only when formatted.
    This changes the behavior from file I/O returning file system corruption
    errors to file I/O returning read-only filesystem errors. The change was
    made for consistency with F2FS and to lock things down as soon as corruption
    was detected.
