* [CHD-3659] [Notifications/Mail/Notes] Watchers will no longer receive a notification about their own sticky notes on tickets.
* [CHD-3654] [Virtual Attendants/Mail/Owner] When using the 'Set owner' action on ticket-based Virtual Attendant behaviors, the owner information will now immediately update in the placeholders.  Previously, additional actions on the same VA behavior would still refer to the previous owner.
* [Virtual Attendants/Orgs] When using the 'Set organization' action on ticket-based Virtual Attendant behaviors, the org information will now immediately update in the placeholders.  Previously, additional actions on the same VA behavior would still refer to the previous org.
* [CHD-3661] [Mail/HTML] When using HTML mode to send email, the 'Code Format' button will now automatically detect whether the selection contains multiple lines.  Previously, the button always used inline code formatting (ideal for variable and file names).  Multiple lines are now wrapped in code block tags (```).
* [CHD-3653] [Worklists/Custom Fields] Fixed an issue with a "Subquery returns more than 1 row" error being displayed on a worklist if a single-value custom field in fact had multiple values in the database.  This only seems to be the case for long-running databases that had imported data into version 4.x from earlier versions.
