That's a really good point. I don't think it would be that hard for Shopify team to implement this. In the meantime app developers should put additional information about development updates in the app description.
@titime Thanks for bringing this up!
As an app developer, I couldn't agree more that this is useful for all involved. As you know there's no dedicated field for this on our end, and we could (some folks do) add change logs into the app description. But we're a little limited on characters allowed in the app description, so a full change log would be difficult, and when we have to choose between explaining app features and benefits, that takes precedence.
That said, I'm definitely not in charge here
