The day has finally arrived, I'm declaring 1.2.0 as stable :) Just pushed and tagged 1.2.0 on the master branch, no "-RC" postfix on this one ;)

Release Notes are here: https://github.com/foosel/OctoPrint/releases/tag/1.2.0
More details on what's in there can be found in the announcement post for the first release candidate: https://plus.google.com/+OctoprintOrg/posts/czVKSZa39TB

Next step is supporting +Guy Sheffer in any way I can to push out a new OctoPi version including that ASAP. And of course getting back into full-blown development mode to make everything even better ;)

Until then you can find the update instructions for getting your OctoPrint version on your OctoPi installation upgraded in the FAQ: https://github.com/foosel/OctoPrint/wiki/FAQ#how-can-i-update-the-octoprint-installation-on-my-octopi-image
