New release: 1.11.1

This first bugfix release for 1.11.x fixes some bugs and user experience issues reported since the release of 1.11.0:

🔒 Security fixes

Minor Security fixes

  • Core: Thanks to some issues with certain third party translations it was discovered that autoescape doesn’t affect strings loaded from translations, specifically any single or double quotes contained therein. Consequently, all places in OctoPrint’s template files have been manually escaped using the existing filters edq (for double quoted strings) and esq (for single quoted strings). I will check if it’s possible to also add some kind of autoescaping (with manual safe marking) there in a future version, so plugin authors should follow future release notes closely (as always).

✨ Features & improvements

Core

  • #5144: The confirmation dialog when deleting a file can now be disabled. See Settings > Features.
  • #5145: Protect against potential misconfiguration of the reauthentication timeout by making sure it’s always >= 0 when checking against it.
  • #5153: It has been made clearer in octoprint.log when the connectivity check is disabled.

🐛 Bug fixes

Core

  • #5149: Fixed a logic error causing connection issues with printers such as Prusa MK3(s) when “wait for start on connect” is disabled.
  • #5151: Fixed a validation error in the comm layer causing a deadlock when trying to connect while there are no serial ports available. Also disabled the connect button when no serial ports are available. The autorefresh in the background that has now been built-in since OctoPrint 1.9.0 should make sure this isn’t a big behaviour change. However, in case that you need to refresh the available ports manually you can always use the little reload button on the header of the connection panel.

Achievements Plugin

  • #5148: Fixed the description of the “The Tinkerer” achievement.

You can also take a look at the changelog on GitHub.
