Question

What does include a latest previous release in Google Play mean?

I'm publishing an update to my app and when uploading the new app bundle Google Play shows this:-

After Scrolling down

So I have one question!

What will happen if I include my previous release vs if I didn't?

Answer 1

A release is a combination of one or more build artifacts that you'll prepare to roll out an app or an app update.

1 example of this would be a release that comes as a Wear OS aab and normal android aab.

For your case, you probably only have a single artifact, so you always use the latest one.
