As the first release of 2021 I present you a bugfix release that fixes two small bugs that were identified in 1.5.x and which turned out to cause a significant amount of support overhead over the past couple of weeks.

Accordingly, the changelog is very short and only consists of these entries:

  • #3849 - Fix plugin install errors (e.g. due to undervoltage) not being properly reported to the client.
  • #3886 - Fix handling of 404 errors upon plugin install

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 💕

Heads-ups

The heads-ups from 1.5.0 still apply, please read them carefully, they might impact you and how you use OctoPrint! Also see the Further Information and Links below for more information, where to find help and how to roll back.
