I wish it hadn’t be necessary to push yet another release out within this short amount of time, but sadly a recent third party dependency update that introduced a critical backwards incompatibility on a patch release forced my hand here. On the upside, you also get a bugfix included that was originally only scheduled to go out with 1.6.0.

Due to this being a hotfix release the changelog is very short and only consists of these entries:

  • #3855 & #3867 - Fix settings merging on the frontend causing issues with array values.
  • Pin watchdog dependency to 0.10.4 to work around backwards incompatibility with the just release 0.10.5 under Python 3.

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 💕
