+### Deployment notes
+
+If your currently installed *Quality-time* version is not v3.36.0, please read the v3.36.0 deployment notes.
+
+### Fixed
+
+- When measuring the 'missing metrics' metric, *Quality-time* was still using an old endpoint to get the data, resulting in a parse error. Fixes [#3855](https://github.com/ICTU/quality-time/issues/3855).
