 - The //retarget// select is not shown when closing or deleting a milestone which has no tickets associated with it (#11366).
 - //Clear default// buttons allow the ticket system default values (e.g. `default_milestone`, `default_version`) to be cleared through the corresponding admin pages (#10772, #11300).
 - The `TitleIndex` macro supports relative path prefixes when used on wiki pages (#11455).
 - CommitTicketUpdater will recognize a ticket reference that includes a trailing `#comment:N` or `#comment:desccription` (#11622).
 - The //Tickets// column of the milestone table on the //Milestone// admin page contains links to the query page showing all tickets associated with the milestone, grouped by status (#11661).
