Chapter 13: Liferay Utility Apps

I was unable to update the Reports and Knowledge Base sections of this chapter. There are strictly EE plugins and were giving errors on deployment. I created a ticket ( [LRDOCS-764](https://issues.liferay.com/browse/LRDOCS-764) ) to revisit this issue when these plugins are on Marketplace.

I also documented deprecated tickets listed in LRDOCS-674.
