On OctoPi 0.12? Be sure to have fixed the python environment!

I have gotten some reports that seem to hint at issues people are running into while updating to 1.3.9 on OctoPi 12. Apparently those issues can be fixed by following the steps outlined in this blog post from November 2017.

Still running OctoPrint 1.3.6? Heads-up!

OctoPrint 1.3.9 includes a couple of dependency updates whose update during switch to 1.3.9 are known to trigger an "update failed" message within OctoPrint's update dialog:

The update did in fact succeed and the issue lies with a change in the underlying update mechanism concerning the dependencies. This problem has been fixed in 1.3.7/1.3.8 and versions prior to 1.3.6 aren't yet affected, so there you won't ever see this message there. If you are still running 1.3.6 though and updating from it, simply run the update a second time through Settings > Software Update > "Check for updates" and clicking "Update now" in the reshown update notification.

Running NGINX as reverse proxy? Be sure to configure HTTP protocol version 1.1!

OctoPrint 1.3.9 updates the internal webserver Tornado from 4.0.2 to 4.5.3. Among many many fixes and improvements this also includes a change (actually a fix) in the websocket implementation that requires you to tell your NGINX to use HTTP 1.1 instead of the default 1.0 to talk to OctoPrint. You can do this by simply adding

proxy_http_version 1.1;

to the location config. The configuration examples have been adjusted accordingly. See also #2526.

Disabled IPv6 and now there are issues with the server after the update? Bind to IPv4 addresses only!

Starting with this release OctoPrint natively supports IPv6 and will attempt to bind to such addresses if it detects support in the underlying OS. If for whatever reason your OS doesn't support IPv6 even though Python's socket says otherwise, you can tell OctoPrint to bind to an IPv4 address only either via the --host command line parameter or server.host in config.yaml. Use 127.0.0.1 for localhost only, 0.0.0.0 for all IPv4 addresses or whatever specific IPv4 address you want to bind to.

Plugin author and still dependent on the legacy plugin bundling flag? Fix your plugin!

As announced with the release of OctoPrint 1.3.6, the legacy plugin bundling flag has now been removed again. Make sure to check and if necessary fix your plugins if you haven't done that so far!

Improvements

  • #652 & #1545 - Added name of user who started a job to job info (see also #2576).
  • #1203 & #1905 & #1797 & #2514 - Added support for plugins to override GCODE analysis provider and live print time estimation with their own implementations through two new hooks octoprint.filemanager.analysis.factory and octoprint.printer.estimation.factory.
  • #1217 - Software Update Plugin: Block the UI in general when an update is in progress (even in browser windows that didn't start it and logged in as user) so that no prints can be accidentally started during that.
  • #1513 - Option to allow sending M0/M1 to the printer instead of swallowing it.
  • #2318 - Gcode Viewer: Visualize "current" print head location with a marker.
  • #2351 - Support for binding to IPv6 addresses. OctoPrint will now default to binding to :: if IPv6 support is detected, and to 0.0.0.0 if not. Both the intermediary server and Tornado are instructed to bind their sockets to both IP versions. Positive IPv6 support detection relies on
    • socket.has_ipv6 being True
    • socket.IPPROTO_IPV6 and socket.IPV6_V6ONLY being available (or redefined in case of Windows) in order to ensure dual stack binding for the intermediary server)
  • #2379 - File and plugin list now use the browser's native scrollbar instead of slimscroll. Slimscroll is still bundled though, in case third party plugins might depend on it.
  • #2487 - Improved documentation of system command configuration (see also #2498).
  • #2495 - Removed unneeded filter from a template.
  • #2498 - Improved documentation of the async flags of custom system commands.
  • #2512 - Log files will now contain client IP as provided by first entry in X-Forwarded-For header (or more if server.reverseProxy.trustDownstream is configured accordingly).
  • #2518 - Display absolute file upload date and time on hover (see also #2630).
  • #2522 - Perform logging to disk asynchronously to avoid slow downs caused by it.
  • #2541 - Added link to instructions to reset passwords. Part of solving #1239.
  • #2543 - Added --no-cache-dir to pip calls to work around MemoryErrors. See also #2535 and pypa/pip#2984 for more details.
  • #2558 - Have the watched folder processor ignore hidden files.
  • #2572 - More error resilience in ItemListHelper against empty child elements.
  • #2573 - Added M118 to commands to never automatically upper case.
  • #2583 - Handle scripts that are part of a job like other lines coming from a job and thus allow them to be kept back using job_on_hold.
  • #2597 - Disabled animation on cancel print confirmation.
  • #2463 - Added documentation for printingarea and dimensions in gcodeAnalysis data model (see also #2540).
  • #2615 - Allowed more granular control over components to be upgraded through the software update plugin in its settings dialog.
  • #2620 - Save ItemListHelper page sizes to local storage.
  • #2642 - Added methods for adding and updating items to ItemListHelper.
  • #2644 - Detect broken symlinks in configured folders on startup (see also further below).
  • #2648 - Allowed class methods as callbacks in view models.
  • A new API endpoint /api/settings/templates allows (admin only) access to information regarding the loaded templates and their order in the UI. That should allow plugins wishing to offer modification of ordering of tabs, sidebar components and so on to retrieve the data they need for that.
  • Have the watched folder processor handle vanished files gracefully.
  • Removed legacyPluginAssets flag.
  • Improved requirement detection in octoprint_setuptools, added unit tests for that.
  • Bundled sockjs-tornado dependency. It hasn't been updated by the author in a while although there exist a number of issues plus patches for them, so we now vendor it.
  • Disabled position logging on cancel by default. If you need this, please explicitly enable it, it is causing too many issues in the field with misbehaving firmware.
  • Extended URL test API to allow whitelist/blacklist check for the returned content type, used that to verify that the webcam snapshot URL actually returns images.
  • Added timeout for position logging on pause/cancel. This should work around firmware which doesn't provide a proper M114 resport that might be unparseable so we won't get stuck in those cases.
  • Migrated file storage metadata to json instead of YAML since it performs way way better.
  • Added missing linenumber to recognized non-fatal error messages.
  • Got rid of some Python 2 only code.
  • Added sanity checks for configured folders (see also #2644):
    • on startup: check they are writable, if not revert to defaults
    • on settings save: check they are writable, if not return an HTTP 400
    • in the settings dialog: allow quick check of writability via test buttons
  • Never send referrers with links
  • Confirmation dialog helper now supports an HTML body.
  • Sort serial ports naturally (e.g. tty1, tty2, ..., tty10 instead of tty1, tty10, ...)
  • Added paused and resumed action commands, see here for details.
  • Added two new hooks for firmware information, octoprint.comm.firmware.info and octoprint.comm.firmware.capabilities.
  • Added view model list to OctoPrint.coreui UI module.
  • Improved logging of FatalStartupErrors.
  • Add sanity check for disabled plugin list (see also #2687 (comment)).
  • Improve logging of exceptions triggered inside the state update worker (see also #2715).
  • Workaround for a potential pip issue when updating components through the Software Update plugin.
  • Fix resend and timeout handling during an active job_on_hold.
  • Updated some dependencies:
    • Tornado to 4.5. Version 5 sadly has issues with web socket handling when access behind haproxy. So far no solution has been found, so we stay at 4.5 for now.
    • jQuery to 3.3.1
    • Several other Python dependencies
  • Announcement Plugin: Don't reload all notifications if one is marked as read.
  • Printer Safety Plugin: Added new detected firmwares:
    • Anycubic Mega
    • Malyan M200
    • CR-10S
    • all Repetier firmware versions prior to 0.92
    • any firmware that reports the THERMAL_PROTECTION capability as disabled to thermal protection warning (see also MarlinFirmware/Marlin#10465)
  • Software Update Plugin: Default to force_base = False for version checks.
  • Virtual Printer Plugin: Allow defining custom M114 response formats.
