Bundled Runtime Manager Agent

This version of Mule runtime comes bundled with the Runtime Manager Agent plugin version 1.5.2.

Migration Guide

XML entity expansion in XML transformers is now disabled by default because it allows DoS attacks. To restore previous behavior use the expandInternalEntities="true" attribute.

XML entity expansion in Jersey is now disabled by default because it allows DoS attacks. To restore previous behavior use the mule.xml.expandInternalEntities=true property.

Processing after a synchronous until successful resulting in a VoidMuleEvent will now continue with the original event.
