+#### Upgrade Instructions
+
+##### Default logging library changed to Reload4j
+
+The default logging library used in the pre-packaged distribution has been changed in version 0.6.3 by accident from
+Log4j to Logback.
+While this change meant that some security issues of Log4j were avoided, it was also a breaking change that was not
+intended.
+This resulted in only warnings being logged by default and also that a Log4j config file was ignored.
+To fix this breaking change, we change the default logging library in this release to [Reload4j](https://reload4j.qos.ch/)
+which is completely compatible with Log4j, but fixes the security issues of Log4j.
+This means that Log4j config files will continue to work with this version.
+
+Note that this only applies to JanusGraph 0.6.
+JanusGraph 1.0.0 uses Log4j2 by default.
