+## Changelog
+
+Compared to the latest release [3.5.10](release_notes_3510.html), the following changes and bugfixes were added.
+
+### Bugfixes
+
+This is a complete list of the
+[merged pull requests](https://github.com/eclipse-ditto/ditto/pulls?q=is%3Apr+milestone%3A3.5.11).
+
+#### Updating MongoDB Java driver to latest bugfix
+
+The latest MongoDB Java driver (which Ditto updated to in 3.5.10) contained a bug, 
+[JAVA-5516](https://jira.mongodb.org/browse/JAVA-5516), which lead to termination cursors obtained via the reactive API.
+
+This leads e.g. to the Ditto [Background cleanup](installation-operating.html#managing-background-cleanup) and
+[Background sync](installation-operating.html#managing-background-synchronization) not working in Ditto 3.5.10.
+
+Updating to the MongoDB driver version [5.1.4](https://github.com/mongodb/mongo-java-driver/releases/tag/r5.1.4) 
+(containing the fix done in [5.1.3](https://github.com/mongodb/mongo-java-driver/releases/tag/r5.1.3) as well), resolves
+seen issues about no longer working background sync and cleanup.
+
+#### Fixes around Docker base image
+
+Additionally, some fixes were done in the Docker image of Ditto, as the baseimage added users for uid `1000` and gid `1000`, 
+which were before used by Ditto.
+
+#### Various security related Helm improvements
+
+Various configurations were adjusted in order to e.g. not run containers with "root" permissions.
