I’m happy to present you the first release candidate of the 1.3.9 release!
The changelog is once again on the lengthy side thanks to the maintenance releases now being spread apart a bit further. Don’t let that scare you though 😉
Here are some highlights from the release notes:
- A very annoying race condition causing OctoPrint to get stuck in “Cancelling” or “Pausing” state was identified and fixed. See also this FAQ entry which outlines the workarounds for this issue if you didn’t yet come across them.
- An observed incompatibility with pip versions 10 and after that caused issues with plugin installation/uninstallation was also identified and fixed (see here for details).
- Added support for plugins to override GCODE analysis provider and live print time estimation with their own
implementations through two new hooks
octoprint.printer.estimation.factory. Feel free to go nuts with this.
- Allowed more granular control over components to be upgraded through the software update plugin in its settings dialog. Instead of performing an “all-or-nothing” update, you may now apply each update individually.
- Added detection for more unsafe firmwares to the bundled Printer Safety Plugin:
- Anycubic Mega
- Malyan M200
- all Repetier firmware versions prior to 0.92
- any firmware that reports the
THERMAL_PROTECTIONcapability as disabled to thermal protection warning (see also MarlinFirmware/Marlin#10465)
- Added a new bundled plugin “Action Command Prompt support” that allows printer firmware to trigger confirmation/decision dialogs in OctoPrint (e.g. for filament swaps).
- The bundled web server Tornado was updated to a newer version to work around issues with client IP logging and other things. This also led to the discovery a heads-up for anyone running OctoPrint behind NGINX - please see the release notes for details on this.
- As announced with the release of OctoPrint 1.3.6, the legacy plugin bundling flag has now been removed again. Plugin authors, please make sure to check your plugins if you haven’t done that so far!
- And of course there were also quite a number of bugs fixed reported for earlier versions, e.g. the logged in user
_apiif the general API key was used to access the API in the same browser instance, inconsistencies in the port and baud rate lists between connection and settings dialog, a race condition in resend handling in case of missing
oks, plus various fixes of typos and grammar in the documentation.
