Quoting Charles Marcus <CMarcus@Media-Brokers.com>:
That said, the biggest reason I see for upgrading often, especially for things like dovecot, is to take advantage of the performance improvements and new capabilities/options.
I've not seen to many lately, but maybe that is due to differences in say mbox versus maildir storage we use?
In fact, there were a couple times when performance got worse after an upgrade, though it was usually restored a release or two later...
I've upgraded only for bug-fixes, security-fixes, or because I needed a new feature in a new release...
On the other hand, dovecot was so fast compared to our old wu-imap server that I don't really care if it gets faster or not! The switch to dovecot was so great anything else since then is just gravy...
Of course, eventually I'm sure dovecot will hit a wall where performance improvements will be negligible, but for now, the difference between the 1.0.x version and 1.2.x is so great that anyone who refuses to upgrade is simply missing out.
Again, this might be storage related, or something... Don't assume it applies to everyone.
