Speaking only for myself, I can think of reasons *not* to upgrade a running instance.

First, there are people using it, and they make a unpleasant, high-pitched whining sound when things change or are disrupted. Second, it takes a bunch of hours out of your life and there are much more rewarding activities. Third, because one hasn't upgraded recently, upgrading becomes incrementally more challenging.

Are you looking for some particular feature or fix in version 1.4.1?
