Looking at the preview builds I do not see anything really significant enough to say there should be a new stable release made and the implication that people should upgrade. There are point fixes but they should apply to a minority of Moneydance users.
However I do see a couple of things in the latest preview releases that I would expect to be the cause of a lot of complaint at least and in this respect that would disqualify them, in my view, from being considered for being a stable release.

Sorry about the less frequent release of updates. I am making progress on a lot of fronts (including the mobile apps) but should still be pushing out updates of Moneydance - we're long overdue! Please don't worry about Moneydance ever being abandoned - that'll never happen.
The changes in the recent previews are mostly fixes for specific issues which should only impact a relatively small number of users, so unless you have an issue fixed in one of those releases there would seem to be little need to upgrade.
