⚠️ Important note on release candidates

This is a Release Candidate of OctoPrint. It is not a stable release: severe bugs can occur, and they can be bad enough that they make a manual downgrade to an earlier version necessary - maybe even from the command line.

You should be comfortable with and capable of possibly having to do this before installing an RC.

Feedback on this RC

Please provide general feedback on this RC in this ticket. An "All is working fine" is valuable feedback as well because it tells me people are actually testing this RC and just not finding problems with it.

If you run into any obvious bugs, please follow "How to file a bug report" - I need logs and reproduction steps to fix issues, not just the information that something doesn't work.


Heads-up for RC testers on OctoPi 0.15.1 with 1.3.12rc1

Those of you who are running OctoPi 0.15.1 and already updated to 1.3.12rc1 will either have to manually update their pip version to something >=10.0.1 or manually update to this second release candidate. I sadly made a mistake in the version limitations introduced to exclude OctoPi 0.14 and lower and thus OctoPrint 1.3.12rc1 won't allow to update itself on OctoPi 0.15.1 with stock pip version.

To manually update pip (via SSH):

source ~/oprint/bin/activate
pip install -U pip
sudo service octoprint restart

You might have to "Force Check for Update" in the Software Update plugin after this.

To manually update OctoPrint (via SSH):

source ~/oprint/bin/activate
pip install
sudo service octoprint restart
