Hello Hans,
> The latest development version works, and I gather it does not differ much > from the "stable" version fairly recent updates (the old development version > become new stable). Not sure what you're referring to here? The latest stable release, which is quite recent, is 2.22.2, which is from the 2.22 series. It has only received bug fixes compared to the previously available stable release, 2.22.1. It does not receive the current development changes. If you want to help as a beta tester for the development release, 2.23.6, or just enjoy its new features, you are of course welcome to do so, but it is what it is: an unstable release. It does differ significantly from 2.22.2.
