Hi I would really like to know how often you upgrade (major) the version you cyrus-imap. I'm undecided if I should run my cyrus 3.0.x until the end of the hardware (3 years from now). I don't really need anything more than what I already have in term of feature. And is it easier to upgrade each time a major release was release or it don't change lot of time.
