This weekend sees the upgrade of our mail service from Zimbra 7.1.1 to version 7.1.3. All updates went without a hitch and the service was unavailable for only 5 minutes on Sunday evening.
Release notes for 7.1.3 are available here.
There were no major changes in this release, just some subtle under-the-hood enhancements and a raft of minor bug fixes.
If anyone spots any new issues, please log a ticket here.
