* [CHD-3231] [UI/Usability] Fixed an issue with the 'elastic' jQuery plugin where leaving a textarea that had resized from new content could shift the rest of the content on the page by a small amount.  This often required an extraneous click on form elements like buttons (i.e. one to focus, one to activate).  This was observed in the mail reply form, and in several Virtual Attendant actions that allow placeholder entry.
* [CHD-3234] [Logins/Activity Log] Fixed an issue with the Activity Log entries for login/logout events when MySQL's strict mode was enabled.
