Marcus Mendes, writing for 9to5Mac:

Up until now, Apple’s App Store promo code system was mostly limited to unlocking a free download, or for auto-renewable subscriptions, letting developers hand out promo codes for discounted trial periods or special offers.

But with the upcoming change, that system is expanding to also cover what Apple calls consumables, non-consumables, and non-renewing subscriptions. In practice, this means mobile games could start handing out codes for free gems or extra lives at a live event, or an indie productivity app could email users a one-time code for discounted unlocks.

To call this feature long-overdue is a huge understatement. So glad to finally see this policy change.
