   * Change udev rules for an instance with `sudo octoprint_deploy/octoprint_deploy.sh replace`
   * Always a good idea to update octoprint_deploy from time-to-time with `git -C octoprint_deploy pull`
 # Recent Changes
+* Multi-camera support (experimental). 
 * If haproxy is used, cameras stream can be placed behind it.
 * Allow making backups of generic instance.
 * Add 'noserial' command line option. Currently for cameras only, this will unset the serial number in cases where cameras are known to share a serial number.
