+### Bugfixes
+
+This is a complete list of the
+[merged pull requests](https://github.com/eclipse-ditto/ditto/pulls?q=is%3Apr+milestone%3A3.4.2).
+
+#### Fixed that Hono Connection config missed trusted certificates configuration
+
+Bug [#1801](https://github.com/eclipse-ditto/ditto/issues/1801), that a custom configured `ca` was ignored for connections
+of type `hono`, was fixed in [#1802](https://github.com/eclipse-ditto/ditto/pull/1802).
+
+#### Background Sync not syncing entities
+
+Bug [#1825](https://github.com/eclipse-ditto/ditto/issues/1825), not syncing non-indexes Things in the search when there
+are many deleted Things, was fixed via [#1824](https://github.com/eclipse-ditto/ditto/pull/1824).
+
+#### MQTT 5 messages sent when Ditto was not connected are not processed
+
+Reported bug [#1767](https://github.com/eclipse-ditto/ditto/issues/1767), causing Ditto not consuming messages sent with
+QoS 1 ("at least once") was fixed via [#1794](https://github.com/eclipse-ditto/ditto/pull/1794).
+
+#### When enriching signals with extraFields, duplicate paths lead to not all fields to be enriched
+
+Bug [#1826](https://github.com/eclipse-ditto/ditto/issues/1826), causing that fields were missing from "enrichment" 
+when using duplicated paths in `extraFields`, was fixed via [#1828](https://github.com/eclipse-ditto/ditto/pull/1828).
+
+#### Fix that a "wrong" JsonPointer in a search RQL query lead to ERRORs
+
+[#1816](https://github.com/eclipse-ditto/ditto/pull/1816) fixes that when a search contained a `filter` (RQL) expression
+with 2 slashes following each other, an "internal server error" (500) was produced instead of a 400 (Bad Request.)
+
+
+### Ditto Explorer UI
+
+#### Fix that non-successful message responses were not displayed in ACE editor
+
+Only successful responses were displayed in the "response" editor when sending messages via the Ditto UI.  
+This has been fixed in [#1810](https://github.com/eclipse-ditto/ditto/pull/1810).
+
+
+### 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.
+
+#### Removed X-Original-URI from NGINX ingress
+
+[#1823](https://github.com/eclipse-ditto/ditto/pull/1823) removes the (non-used) `X-Original-URI` header previously
+set by the nginx ingress.
