+
+## Changelog
+
+Compared to the latest release [3.5.6](release_notes_356.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%3A3.5.7).
+
+#### Fixed that configuring "oauth2" based authentication for "devops" access does not allow to use a different OpenID connect provider
+
+Reported issue [#1946](https://github.com/eclipse-ditto/ditto/issues/1946), which caused that a configured `oauth2` based
+authentication of the `/devops` resources was not working with a different OIDC provider than used for the default authentication, 
+was fixed by PR [#1948](https://github.com/eclipse-ditto/ditto/pull/1948).
+
+#### Fix performance regression issue when running against MongoDB 6
+
+An `aggregation` query done by Ditto as part of background deletion was quick with MongoDB 5, however the MongoDB 6 query planner
+chose to use another index to run that aggregation query than MongoDB 5.  
+Depending on the amount of data in Ditto, this could lead to a 500 times higher query time, resulting in a lot of unneeded
+disk IOPS in MongoDB.
+
+The fix provided in PR [#1956](https://github.com/eclipse-ditto/ditto/pull/1956) provides the option to configure a 
+hint which index name to use should provide the option to fine-tune as needed.  
+By default, the mentioned query now is configured to use the default index `"_id_"` which should be best for that 
+specific case.
+
+
+### Helm Chart
+
+The [Ditto Helm Chart](https://github.com/eclipse-ditto/ditto/tree/master/deployment/helm) contained some configuration 
+bugs and enhancements which are also addressed with this bugfix release.
+
+#### Fix Ingress Websocket authentication
+
+PR [#1953](https://github.com/eclipse-ditto/ditto/pull/1953) provides a fix for authentication of the `/ws` (WebSocket)
+resource by the nginx configured as "Ingress" in the Helm chart.
+
+#### Add possibility to customize image used for pod-deletion-cost annotation patching job
+
+PR [#1954](https://github.com/eclipse-ditto/ditto/pull/1954) provides the option to customize the image to be used
+for the `pod-deletion-cost` annotation jobs.  
+This can e.g. be useful in order to use a custom image and/or a private docker registry for this image.
