A brand new App Store
Apple gave a few of its stock apps facelifts but the App Store is without a doubt the most noticeable. Nearly every aspect of the app has been refreshed in ways that will be welcome to users and developers alike.
The new app launches on a new screen called "Today," which provides a feed of editorial content about certain featured apps along with themed collections like "Games for Airplane Mode," or "Rule at Road Trips."
Elsewhere, Apple has separated its Store into two sections: one exclusively for games and one for everything else. The distinction shouldn't be surprising given the sheer dominance of games in the App Store — they are consistently the most downloadable and profitable category — but both tabs are a nice change from the previous store's more generic "featured" section.
There are also a number of developer-centric improvements to the App Store. Developers can now respond to individual reviews and choose when to reset their ratings (previously, ratings reset with each update). And, of course, iOS 11 marks the official end of legacy 32-bit apps so older apps that haven't been updated in some time will no longer appear in search results and apps you have previously downloaded will no longer work.
