   * Elasticsearch: Support for EOL version 6.6 is discontinued.
 
+  * Logging: `--console-log`-flag of `gerrit.war daemon` respects `log.textLogging`
+    and `log.jsonLogging` options

+    Change in the default behaviour of the `--console-log` flag. Since
+    `log.textLogging` in the `gerrit.config` is `true` by default, using the
+    `--console-log`-flag now writes logs to the `error_log`-file in addition
+    to stderr by default. This can be avoided by setting `log.textLogging = false`.
