1.10.0rc1

⚠️ 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.

Thanks!

Things to take a closer look at

For this RC, these things should get a closer look while testing, if possible:

• Proper behaviour when using the included web interface as well as any third party clients at your disposal.
• User and group management functioning as expected.
• Plugin installation functioning as expected.
• Application key management functioning as expected. Authentication workflow with third party clients at your disposal (e.g. slicers) works as it should.

🔒 Security fixes

• Severity Moderate (4.2): It was possible for admins to perform password changes for their own account or others via the Settings dialog without having to re-enter their password. A malicious administrator or an attacker having taken over an administrator's session could have used this to effectively lock out users from their accounts.

  This has now been fixed by introducing a reauthentication requirement on changing passwords in the Settings. Unless the user has authenticated with their password (and other credentials possibly in the future) in the past 5min of their login session, a reauthentication dialog to re-enter the credentials will be shown, and only after that has done properly will the request work. This reauthentication dialog has also been added to other critical operations (adding, changing and deleting users, adding, changing and deleting groups, installing plugins, revealing the deprecated global API key, generating, revoking, revealing and granting application keys, accessing the recovery page). The reauthentication timeout of 5min is configurable via config.yaml, see the documentation.

✨ Features & improvements

Core

• #4586: Added the capability report of the firmware as returned from M115 to octoprint.log and also the systeminfo bundle in shape of a new m115.txt file that gets generated if the bundle gets created while there's an active printer connection.
• #4617: Added a manual refresh button to the webcam view that allows to reload the underlying webcam stream (if webcam plugin supports that by having implemented onWebcamRefresh in its viewmodel, otherwise the button will be a no-op). Only gets made visible when hovering over the webcam.
• #4681: Added information on old and new file to the "file already exists dialog". See also PR#4721.
• #4685: Implemented a custom versioning tool to replace the so far used customized version of versioneer that has gotten quite long in the tooth. It should behave the same, but with way less code to keep maintained.
• #4714: Added a new dialog that gets displayed when the printer reports an unrecoverable error, containing the error message, what happened due to that error (print cancellation, disconnect), if available a link to an FAQ entry, the last lines of communication and a big reminder that printer errors are printer errors and not OctoPrint's fault. The dialog will be automatically opened on connected clients, however it can also be accessed later by clicking on the new error icon added to the printer state panel.
• #4747: Made temperature graph time axis always show the configured cutoff interval. That should prevent any jumping of events.
• #4760: Made OctoPrint compatible to Python 3.12.
• #4764: Refactored the Tornado/WSGI interface based on the current Tornado code to make it async. That fixed the issue with connection reuse and as a very welcome side effect also very much increased the performance of the internal web server in general. Long running Flask endpoints now should no longer be able to fully block Tornado, and requests can get parallelized by the frontend, leading to a large reduction of time needed to fully load the UI.
• #4838: Improved performance of the internal settings data structure, reducing the initial settings fetch right after a server start from 2s+ to 400-700ms.
• #4843: Made the upload drop zone an optional feature that can be disabled in the settings. See also PR#4853.
• #4866: Added axis labels to model size info. See also PR#4898.
• #4880: Removed scripts folder from repo.
• #4881: Display an error popup in case of startup issues due to inaccessible application directories.
• #4892: Keep tool change controls enabled while printing.
• #4921: Added graph markers for the Connected and Disconnected events to the temperature graph.
• PR#4743: Migrate from netifaces to the pretty much drop-in replacement netifaces2, since the former has been abandoned.
• PR#4752: Send initial history message when the web socket subscription is changed.
• PR#4820: Added file and print head position to paused and cancel event & log entries.
• PR#4833: Improved first run wizard safety hints. They are now visually more alerting and the wizard now also requires the user to acknowledge having read and understood each warning by checking a checkbox.
• PR#4874: Added new Thermal Malfunction error to recognized as a kill inducing error on Marlin.
• PR#4899: Removed the upper version pin for the argon2-cffi dependency.
• PR#4918: Made target temperature lines in the temperature graph dashed. Improves accessibility for color blind users.
• PR#4928: Further improve screen reader accessibility.
• Use a file <basefolder>/.incomplete_startup to flag an incomplete startup instead of a config.yaml entry. Makes it easier to reconfigure the server in CI situations.
• Improved the UX of the systeminfo CLI. octoprint systeminfo will now generate a bundle in the current directory even without an explicitly added . parameter. octoprint systeminfo --short has been added to generated an abridged version directly on the command line. This should clear up issues we saw in the past where people forgot the . and then just pasted the abridged text only version when in fact a bundle was needed and requested.
• Added progress to PrintFailed, PrintCancelled and PrintPaused events.
• Added operation to FileRemoved event. Allows distinguishing between a removal due to an actual remove or a move.
• Added a funding banner to the About dialog and a funding link to the footer.

Achievement Plugin (✨ New!)

Added a new bundled Achievements plugin! OctoPrint will now internally record some instance stats and monitor some events and based on that give out various achievements. This version contains 36 achievements, 22 of which are hidden and for you to be discovered. Additionally, the instance stats are also being recorded per year to make it possible in the future to give you some yearly stats overview of your OctoPrint and printing use.

Action Command Notification Plugin

• #4326: Added ability to ignore incoming printer notifications based on a filter regex. This is to combat notification spam by firmwares which abuse the feature. Please talk to your firmware provider about not abusing the notification action command for things triggered by the user, e.g. mirroring M117 commands! See also PR#4886.

Application Keys Plugin

• #4894: Added application key details incl. QR Code to user settings. See also PR#4895.

Classic Webcam Plugin

• #4837: Apply the selected camera aspect ratio to its video tag.

Virtual Printer Plugin

• PR#4799: Added support for generating an area report as part of the response to M115.

Documentation

• #4787: Added a note to the documentation of the SettingsPlugin mixin that updating settings will trigger a reload screen.
• #4852: Updated the plugin tutorial to reflect current CLI outputs.
• PR#4823: Slight improvement on the pause GCODE script.

Testing & CI

• #4908: Automatically publish release build artifacts on GitHub Releases as well as PyPI.
• Updated the node-qunit-puppeteer version to combat some JS unit test flakyness.
• Run the E2E tests against the lowest and highest supported Python version, to make sure things work on both edge cases.
• Updated playwright used for the E2E tests.

• Fixed some warnings in the vendored awesome-slugify dependency.

Classic Webcam Plugin

• #4885: Fixed snapshot timeout & SSL validation settings.

Discovery Plugin
