I've been running cyrus imapd version 2.1.10 with cyrus-sasl-2.1.9 for a while, and apart of some glitches with Berkely-dB 4.1.25, am quite pleased with it. From this mailinglist I understand that the Berkeley-dB bug has been solved, so that sounds like a good reason to upgrade. Is this particular bug-fix already in a stable release? I'm planning to upgrade to 2.1.12, given the 'alpha' status of the 2.2 branch.
Secondly, most of my mail-users use Mozilla or Outlook. Both open multiple connections, and because of this, mail you've already read tends to become unread again. I've heard about a patch to make cyrus write these changes to disk right away to keep them synchronized between connections. Where to find such a patch? Is it already part of the cyrus tree?
From the documentation, I understand that (I won't change Berkely-dB versions) upgrading from this version of Cyrus to a more recent one shouldn't be a problem, just stop the server, replace the binaries, and start it again. Is this enough of a plan, apart from making a full backup first?
