+
+## Changelog
+
+Compared to the latest release [3.3.5](release_notes_335.html), the following changes and bugfixes were added.
+
+### Changes
+
+
+### Bugfixes
+
+This is a complete list of the
+[merged pull requests](https://github.com/eclipse-ditto/ditto/pulls?q=is%3Apr+milestone%3A3.3.6).
+
+#### [Fixed providing Ditto Adaptable information in the "_context" of an SSE event](https://github.com/eclipse-ditto/ditto/pull/1716)
+
+Previously, the optional `_context` of an SSE subscription only contained the headers.
+
+The fix also adds (same as for the [`NormalizedMessageMapper`](connectivity-mapping.html#normalized-mapper)) the `topic`
+and `path` of the underlying Ditto protocol message.
+
+#### [Fixed using "/cloudevents" endpoint for other entities than things](https://github.com/eclipse-ditto/ditto/pull/1724)
+
+When sending `Policy` commands via the `POST /cloudevents` endpoint, the HTTP response was never completed successfully, 
+as the cloudevents implementation made the assumption to always handle thing commands only.  
+This has been fixed, now also Policy commands may be sent via the Cloud Events endpoint.
+
+
+### Helm Chart
+
+The [Ditto Helm Chart](https://github.com/eclipse-ditto/ditto/tree/master/deployment/helm), which was enhanced and changed 
+a lot for version 3.3.0, contained some configuration bugs which are also addressed with this bugfix release.
+
+#### [Support for basic nginx-ingress authentication](https://github.com/eclipse-ditto/ditto/pull/1702)
+
+When using "Ingress" in the Ditto Helm chart, now also users via nginx "Basic auth" can be authenticated.
