⚠️ 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.



  • More resilience against third party plugins that happily block or kill important startup threads
  • Improved backwards compatibility of the sarge dependency by monkey patching it to support the old async keyword parameter. Plugin authors are still advised to switch to the new async_ parameter if running against sarge>=0.1.5, unmodified plugins should continue to work now however. For reference, OctoPrint 1.3.10 requires sarge==0.1.5post0.
  • Pi Support plugin: Better wording on the "undervoltage & overheat" popover & added a link to the FAQ entry
  • Printer Safety plugin: Micro3D printers running stock or iMe firmware are now detected as unsafe

Bug fixes

  • #2897 - Improved error resilience of is_lan_address so an error during its execution no longer nukes requests
  • #2898 - ForceLogin plugin no longer interferes with websocket messages sent by plugins right on UI load but instead puts them into a (limited) backlog and then sends them out in received order once the user has authenticated on the socket.
  • #2903 - Backup plugin: Support for ZIP64 extensions for large zip files
  • #2903 - Backup plugin: Better error reporting
  • #2908 - Tracking: Use the file's path instead of just the name for file name hashing.
  • Logout socket on UI logout
  • Tracking: Fixed homepage link
