New release candidate: 1.3.12rc2

Blog
1

This second RC of 1.3.12 fixes a regression observed with the first one, and a bug fix and improvement that while not technically regressions make sense to include in this release due to usefulness:

Improvements

  • #3271 - Extend safemode to also disable third party language packs

Bug fixes

  • #3270 - Properly escape translation strings in single/double quoted template locations
  • #3272 (regression) - GCODE viewer: Fix out-of-sync & layer slider issue
  • Fix minimum pip version for OctoPi 0.15.1 (regression)

Sadly, due to a wrong version check included in 1.3.12rc1 there’s also another heads-up for those of you who are on OctoPi 0.15.0 or 0.15.1 and already updated to OctoPrint 1.3.12rc1:

Heads-up for RC testers on OctoPi 0.15.0 and 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 https://github.com/foosel/OctoPrint/archive/1.3.12rc2.zip
sudo service octoprint restart

You can find the full changelog and release notes as usual on Github.

Special thanks to everyone who contributed to this release candidate and provided full, analyzable bug reports!

As the past RCs have shown me that a lot of people appear to be unaware of this: Please do not install this RC if you expect a fully stable version. It is not a stable release, it is a release candidate: severe bugs may occur, and they might be bad enough that they make a manual downgrade to an earlier version necessary - maybe even from the command line.

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

If you want to and can help test this release candidate, you can find information on how to switch to the “Maintenance RCs” release channel in this guide if not already done (also linked below).

Please provide feedback on this RC. For general feedback you can use this ticket on the tracker. The information that everything works fine for you is also valuable feedback 😄. For bug reports 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 so make sure to fill out all fields of the issue template.

Thanks!

Depending on how the feedback for this release candidate turns out, I’ll either look into releasing 1.3.12 or fix any observed regressions and push out a new release candidate ASAP.

I just upgraded from RC1 a few minutes ago. No issues on the upgrade. I don't know when my next print job will be, but I'll try and make a point to look at the GCODE viewer.

this is the first time it happened to me but might not be related to 1.3.12rc2 .... during printing ( State: Printing ) I got the "Update Available" notice window asking to update some plugin.. I of course did not try to update anything in the middle of the print but I kinda assumed that while state is "printing" octoprint is not checking for updates neither :smiley:
