This release is primarily a bugfix release; most notably, it addresses
compatibility issues with recent versions of the Encode perl module.
Notable changes include:

Email
 * Cope with Encode version 2.33 and later, which altered their internal
   functionality and caused RT to double-encode Subject lines in
   outgoing email.
 * Fix HTML rendering errors in dashboard emails.
 * Fix overzealous quoting around decoded MIME words.

Administration
 * In the rights UI, entering the name of a user or group which already
   has rights will now correctly select them for rights granting, as if
   their name had been selected.
 * Display types in the "applies to" dropdown for custom fields in
   consistent order
 * Paginate the Queues list in the administrative interface into 50
   results per page.
 * Support for cascading selections with a multiple-select parent.
 * Clarify that $ParseNewMessageForTicketCcs only applies to new, and
   not existing, tickets.
 * Clarify how an undefined $RTAddressRegexp is treated, and that it
   does not come at any notable performance penalty.

Logging
 * Fix verbosity of syslog messages; now only the 'debug' level includes
   originating filename and line.
 * Include process ID in log messages, for ease of isolation in a
   multi-process environment.
 * Log the From: address of incoming mail which triggered an error, for
   ease of debugging.

Other Bugfixes
 * Avoid linking trailing punctuation, or html tags, in URL anchors in
   MakeClicky
 * Fix the Quick Search (QueueSummary) portlet when non-lowercase statuses are used.
 * Show Date and DateTime custom fields in the user's format and time
   zone in search results.
 * Allow rt-email-group-admin to be passed an email address that RT is
   not already aware of.
 * Show submitted content from the user on errors in REST submission,
   for ease of re-editing and re-submission.
