 # Recent Changes
+* 0.1.3, printer and camera detection now done with dmesg instead of journalctl. This allows faster timeouts when a device is detected by USB port but it does not have a serial number.
 * Write /etc/octoprint_deploy if missing (older version system preparation)
 * Add option for plugin installation during system preparation.
 * Enable ssh.
