+### Bugfixes
+
+This is a complete list of the
+[merged pull requests](https://github.com/eclipse/ditto/pulls?q=is%3Apr+milestone%3A2.3.2), including the fixed bugs.
+
+#### [Fix search consistency for failed patch updates](https://github.com/eclipse/ditto/pull/1300)
+
+The search index could get never consistent for some things, as failed "patch updates" to the search index were not 
+retried.
+
+#### [Fix search sync infinite loop](https://github.com/eclipse/ditto/pull/1301)
+
+Forcing a full search index update could lead to an infinite loop when processing "Thing Deleted" events.
+
+#### [Ignore DittoMessageMapper for Hono delivery failed notifications](https://github.com/eclipse/ditto/pull/1299)
+
+Delivery failure notification sent via Eclipse Hono with content-type `application/vnd.eclipse-hono-delivery-failure-notification+json`
+are now excluded to be handled by the default `DittoMessageMapper` used in connections.
+
+#### [Fixed potential race condition in LiveSignalEnforcement](https://github.com/eclipse/ditto/pull/1305)
+
+For live response messages a race condition could happen where a 503 ("Thing not available") exception was produced
+instead of running in a 408 timeout.
