+### Changes
+
+
+### Bugfixes
+
+This is a complete list of the
+[merged pull requests](https://github.com/eclipse-ditto/ditto/pulls?q=is%3Apr+milestone%3A3.5.2).
+
+#### Fix wrongly done invalidation of non-existing cached policy entry in search
+
+A [bugfix for Ditto 3.5.0](https://github.com/eclipse-ditto/ditto/pull/1872) introduced another side effect regarding
+policy imports. When an imported policy was deleted and added again with the same id, the affected things were not updated
+in the search index.
+PR [#1889](https://github.com/eclipse-ditto/ditto/pull/1889) provides a fix for this.
+
+#### Fix retrieving JSON arrays via fields selector was broken
+
+Reported bug [#1888](https://github.com/eclipse-ditto/ditto/issues/1888) caused when selecting a JSON array via the
+`fields` selector, the array's content was not returned.  
+PR [#1890](https://github.com/eclipse-ditto/ditto/pull/1890) fixes that.
+
+#### Several small fixes and improvements in the Ditto UI
+
+PR [#1891](https://github.com/eclipse-ditto/ditto/pull/1891) provides some fixes around the Ditto UI, e.g.:
+* send message with timeout `0` and no payload showed incorrect error in the response field
+* added category column on connection logs, so you can distinguish source and target log entries
+* connections js editors had wrong read-only behavior
+* connection log details ace editor now with word wrap, otherwise it is hard to read long message in one line
+* Bugfix: filter on incoming messages does not work on new incoming messages
+
+Additional fixes for the UI contained in this release:
+* fix policyId search slot submitting form
+* fix that sending a payload `0` as message payload did not work
+* add form to authentication popup, submitting via enter
+* open authentication popup when backend responds with error needing authentication
+
+
+### 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 hook-scripts configmap missing in Helm pre-upgrade Hooks
+
+The newly introduced [calculation of pod deletion cost via a Helm hook](https://github.com/eclipse-ditto/ditto/pull/1871)
+was missing setting up the configmap containing the script properly.  
+This was fixed in [#1880](https://github.com/eclipse-ditto/ditto/pull/1880).  
+PR [#1886](https://github.com/eclipse-ditto/ditto/pull/1886) in addition fixes a wrong name variable used for the configmap.
