Major Description
Ranger has two different Tomcat versions, 7.0.55 and an older dependency on commons-el (5.5.23). This task is to update the latter dependency so that we can have unified Tomcat versions. In addition, this patch contains an update to use Tomcat 7.0.68, due to numerous security vulnerabilities that have been recently fixed:
