General Notes

When upgrading make sure you compare your xwiki.cfg, and web.xml files with the newest version since some configuration parameters may have been modified or added. Note that you should add so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.

Mail API Unique Message Identifier

In order to solve XWIKI-12165, the unique identifier of each mime message sent has been change to a SHA1 based on the Message-ID header and the list of recipients of the mails, ensuring uniqueness during a newsletter or mailing sending. To introduce this change, the MailContentStore and the MailListener API has been broken, and now use a new ExtendedMimeMessage instead of the simple MimeMessage for all arguments. The values messageId returned or used as argument in the API is no more equivalent to the Message-ID header, but is now the unique identifier returned by ExtendedMimeMessage#getUniqueMessageId(). Finally, the MessageMimeMessageFactory now returns cloned MimeMessage without changing the Message-ID.
