My only advice is DO NOT apply RU2, they made some changes for HTML code in the description field for Request/Incidents/Problems and Manual Notify, its buggee. When viewing the Manual Notify in Activity Logs there was HTMPL code. I got a test patch, and it corrected it. Also, I here there are some problems with mail eater.
If you use, the Reports on a ticket, the detail report still has HTML code in the report for manual notify, also hovering over the description of a manual notify in the Activity Log has html code also. Both of these reported, but no ETA on test patch.
Also, when working with scratch pad, the description does not transfer to the ticket, if hit the 'New' button. Was fixed in 17.4.1, but may be broke again in 17.4.2
Broadcom is talking about having this resolved in RU3.
