+* Fixed issue #10470: The WebUI now shows potential errors and details which occured using _api/import (e.g.
+  unique constraint violated).

 * Added startup option `--query.optimizer-rules` to selectively enable or disable
   optimizer rules by default. The option can be specified multiple times, and takes
