+
+### Bugfixes
+
+This is a complete list of the
+[merged pull requests](https://github.com/eclipse-ditto/ditto/pulls?q=is%3Apr+milestone%3A3.8.2).
+
+#### Fix excessive AskTimeout errors during rolling updates / shard rebalancing
+
+PR [#2241](https://github.com/eclipse-ditto/ditto/pull/2241) fixes a long encountered issue where during rolling updates or shard rebalancing
+excessive `AskTimeoutException` errors were logged for commands sent to things during recovery time from the database.
+
+This fix should stabilize restarts and e.g. rolling updates of Ditto clusters significantly.
+
+### Helm chart
+
+#### Make helm templates openshift SCC compliant
+
+PR [#2242](https://github.com/eclipse-ditto/ditto/pull/2242) fixes another issue in the Helm chart to deploy Ditto on OpenShift clusters.  
+It fixes to add a service account to the Ditto UI and injects a configured OpenShift security context to the nginx 
+containers of Ditto (nginx as reverse proxy, Ditto UI and Swagger-UI).
