Breaking changes:
* On-disk backups are now retained for a minimum of 3 days instead of 14. Beyond that the user is responsible for making off-site copies.
* IMAP no longer supports the legacy SSLv3 protocol. SSLv3 is now known to be insecure. I don't believe any modern devices will be affected by this. HTTPS and SMTP submission already had SSLv3 disabled.
