Apple released a new set of App Store Guidelines, with three major changes. One of the changes is the result of a previously announced settlement agreement with a group of app developers in the United States.
It specifies that developers are permitted to inform their customers about other payment methods available outside of their app. Another new guideline explains that while apps may request customer information such as name and email, the request must be optional for the user and should not prevent them from using the app. The third guideline has nothing to do with legal action and simply describes how developers can use a new App Store feature called in-app events, which will be available next week.
