+#### Enhancements in Ditto explorer UI
+
+The UI was mainly enhanced with new features in a single PR, [#1773](https://github.com/eclipse-ditto/ditto/pull/1773).  
+In detail, the following improvements and fixes were added:  
+* add a tab "Message to Thing" to send thing messages
+* add a loading spinner to the "Send" (message) button and deactivate it while sending
+* update a complete Thing using "PATCH" and with the new 3.4.0 header "if-equal: skip-minimizing-merge"
+* only send eTag if it could be retrieved when updating complete thing
+* added missing `ilike` predicate to the search slot
+* made UI more responsive for small screens
+* prevent browser for doing autocomplete in the "search" input field
+* increase size of the "Things" JSON editor - keep sizes and position of other JSON editors as they were
