* [Virtual Attendants/Mail Filtering] Virtual Attendant Mail Filtering behaviors may now set the sender 'is defunct' and 'is banned' fields as actions.  This makes it possible to ban/unban a sender during mail filtering, and to remove the defunct flag when a previously defunct sender writes a new incoming message.
* [Virtual Attendants/Mail Filtering/Simulator] Fixed an issue with using the Virtual Attendant Simulator on Mail Filtering behaviors.  Due to the way that the event works in conjunction with the parser, the underlying fields (i.e. those not set by the simulator's form) didn't have any values set.  This made it difficult to simulate behaviors that looked at related records; for example, getting or setting values for the sender as an action during mail filtering.  The issue was solely with the simulator; the actual events always worked properly.
* [CHD-3307] [Mail/Parser/Defunct] The 'defunct' flag will now be automatically removed from a sender's record if they send a new incoming message.
* [CHD-3304] [Mail/Profiles/Permalink] When displaying a mail conversation, each expanded message now contains a 'permalink' link below the headers.  This makes it easy to send a link to another worker regarding a specific message.  In addition to scrolling the browser down to the appropriate message, the message will also be briefly highlighted for a visual cue.
* [Mail/Profiles/Comments] When displaying a mail conversation, each comment now contains a 'permalink' link in the top right.  This allows workers to exchange URLs that will focus a specific comment in the timeline.  Just like the permalinks for messages, the focused comment will show a highlight effect as a visual cue.  The focused message will also be maximized automatically.
* [Mail/Profiles/Usability] When viewing a mail conversation timeline, the 'minimize' and 'maximize' links will now only be shown for the message under the mouse cursor.  This improves usability by reducing the number of links on the page at a given time.
* [Mail/Usability] When clicking into a ticket from a message worklist, the conversation will now automatically focus and expand that message.
* [CHD-3302] [Mail/Sticky Notes/Watchers] Creating a sticky note on a ticket message will now automatically notify any watchers on that ticket.
* [Mail/Sticky Notes/Usability] When displaying a sticky note, a 'permalink' link is now available in the top right.  This allows workers to share a URL that automatically focuses a particular note.
* [CHD-3300] [Support Center/Knowledgebase/Usability] In the Support Center, the number of knowledgebase articles displayed per page in worklists is now a configurable option.
* [CHD-3297] [Mail/Sticky Notes] Fixed a bug in ticket conversations where sticky notes were no longer displayed for a particular message after minimizing and maximizing it.
* [CHD-3296] [Groups/Setup/Buckets] Bucket names may now be up to 64 characters in length.  When editing a bucket, the form will now enforce this maximum length.
* [CHD-3295] [UI/Worklists/Usability] The '(dismiss)' option for worklist helpers is now consistently located in their top right corner.  Previously, an 'undo' helper showed dismiss on the left.
