I was hoping to avoid this to be able to fully concentrate on 1.12.0, but sadly a bug with PrusaSlicer’s webview crept into 1.11.6, and so here is the second release of 2026, a bugfix release for 1.11.x, fixing that and a bunch of other issues:

🐛 Bug fixes

Core

  • #5235: Add custom parser for User Agent under Prusa Slicer’s webview, fixing an UI loading error
  • #5240: Use the right capability for registering active position autoreporting
  • #5248: Fix checkboxes not showing for unrendered timelapses
  • #5249: Fix response behaviour on missing subgroups on access management API
