This first bugfix release for 1.7.x fixes two bugs discovered in 1.7.0 after its stable release (one in the handling of gcode files containing a #, one in the sorting of plugins in the Plugin Manager) and also provides a mitigation for a very rare issue where attempting to enable low latency mode on the printer (a new feature in 1.7.x) causes connection issues:

  • #4267 - Properly escape names of uploaded files and timelapses containing a #. Not doing so would make such files unmanageable through the core UI.
  • #4273 (PR) - Plugin Manager: Fix a wrong sorting selected in the list of installed plugins and the list of plugins on the repository.
  • #4292 - Set requesting of low latency mode on the serial connection to disabled by default, as there’s a small number of users for which this causes issues in connecting.

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

Like every single release (and release candidate) of OctoPrint ever since early 2016 this release was made possible only through your continued support of my work 💕
