What ships today is the direct download on this page, and everything above describes it. A Mac App Store edition is built and waiting on Apple's review — we can't give a date for it, and nothing on this page is a promise that it will arrive. No Setapp.
The two editions are not interchangeable. The App Store one is a paid app bought once from Apple: no account with us, no activation code, refunds through Apple. It also runs sandboxed, so its library lives inside the app's own container — importing copies your files rather than cataloguing them where they sit, and external volumes, network volumes and handing a file to an external player are direct-download only. A licence bought here does not carry over to an App Store install, or the other way round.
The licence agreement, privacy policy and support page describe both editions and label every clause that applies to only one. This site stays the source of truth for pricing and the latest direct build.
