Apple today is releasing updated App Store Guidelines with the goal of clarifying how it will approach new technologies, like game streaming services, App Clips and widgets, in addition to better detailing its stance over how and when it will collect in-app purchases from certain categories of apps. The changes arrive at a time when Apple is battling in court with Epic over its requirements regarding the use of in-app purchases. The company is also seeing its App Store business scrutinized by regulators over monopolistic practices in the U.S., E.U. and Australia, and elsewhere.
