+The year is coming to an end, and while I'm currently mostly focused on 1.12.0 (and Moonraker & Bambu Connector Plugins for the new comm layer), I still wanted to push out
+this bugfix release for 1.11.x with fixes for two issues that were reported in the past few weeks, and a logic error I spotted during development:
+
+> **🐛 Bug fixes**
+>
+> _Core_
+>
+> - [#5206](https://github.com/OctoPrint/OctoPrint/issues/5206): Workaround for a regression in Tornado 6.5.x, causing file uploads with non-latin-1 characters in the name to fail.
+> - Fixed logic error in pure-python fallback of `search_through_file` helper
+>
+> _Backup Plugin_
+>
+> - Apply `--no-build-isolation` during installation of plugins with legacy packaging
+
+You can also take a look at the [changelog on GitHub](https://github.com/OctoPrint/OctoPrint/releases/tag/1.11.3).
