Some of you may be aware that Greg has released an untested “one-click upgrade” feature in the latest release (w1.5.1 and w1.4.5).
I will be releasing 1.4.4.1 hopefully in a few days, or less if I have enough spare time. At this stage I do not intend including that feature. Perhaps once it has undergone more testing and use it might be worth considering but for now I see little benefit and plenty of possible issues.
