That's good, I hadn't seen that update! I've been using the app for 5+ years and it doesn't appear to have changed its feature set or UI in that time.

My main concern is OS updates and AirPlay protocol changes breaking it, which would mean that it would no longer fulfil its purpose. AirPlay, being a proprietary protocol, is ripe for breaking third party integrations.

Then you can safely ignore your other concern:

> doesn't appear to have changed its feature set or UI

Those things aren’t related, you don’t need to change the UI or features to maintain core functionality.

Just a side note: I hoped AirPlay was stable after so many years, but everyone may already know that AirPlay 2 is a change that at least in my use case, made all my old Macs running older macOS and AirPlay 1 incompatible with newer third party hardware and hardware that updated firmware to AirPlay 2. Yes, I'm talking about iTunes! At least all my Airport Expresses still work fine! lol

I wouldn't have known that because their "check for updates" function doeesn't seem to work, even when triggered manually. I'm on 3.3.6, which is just a couple point versions behind latest.

I've been a happy paid AirFlow user for about a decade now, but I realize it's small indie sometimes buggy software.

> But even if it was older, once an app fulfills is purpose and is free of bugs and security holes, does it still need to be updated constantly?

Subscription-based software: "Hold my beer!"

(This isn't one of those, which is great, I might buy a license just to support the ecosystem of regular paid apps).
