Two big changes here. One is allowing third-party app stores to exclusively offer their own apps (I guess removing the requirement that they accept other apps). And the second is allowing apps that meet certain requirements to be installed directly from the publisher’s website:
> Apple's specific criteria, such as being a member of the Apple Developer Program for two continuous years or more and having an app with more than one million first installs on iOS in the EU in the prior year, and commit to ongoing requirements, such as publishing transparent data collection policies
But as you can see you won’t be seeing indie apps distributed in this way. Though, to be fair, for most indies the App Store with the old rules is probably the best deal available to them.
