* 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.
