+
+#### Fix exceptions in WebSocket due to wrongly formatted added "EntityId" header
+
+Ditto release [3.6.5](release_notes_365.html) introduced an improved log messages for errors in WoT validations, adding
+the Thing's ID to the log message. Internally, a change was needed to always provide the thing's ID as internal header.  
+This added header had however the wrong format, which caused exceptions e.g. in the Ditto WebSocket handling.
+
+This was reported in issue [#2096](https://github.com/eclipse-ditto/ditto/issues/2096) and was fixed via PR 
+[#2097](https://github.com/eclipse-ditto/ditto/pull/2097).
+
+As this is a very critical bug, a bugfix release containing just this one fix is provided: `3.6.9`.
