Android 13 deep dive: every change up to DP2, thoroughly documented

Building on the foundation laid by Android 12, described by many as the biggest Android OS update since 2014, this year's upcoming Android 13 release refines the feature set and tweaks the user interface in subtle ways. However, it also includes many significant behavioral and platform changes under the hood, as well as several new platform APIs that developers should be aware of. For large screen devices in particular, Android 13 also builds upon the enhancements and features introduced in Android 12L, the feature drop for large screen devices.

Android 13 is set for release later this year, but ahead of its public release, Google has shared preview builds so developers can test their applications. The preview builds provide an early look at Android 13 and introduces many - but not all - of the new features, API updates, user interface tweaks, platform changes, and behavioral changes to the Android platform. In this article, we'll document all of the changes that we find so you can prepare your application or device for Android 13.

This is a long and detailed article, and both users and developers alike should be able to find some interesting information in here. You might want to set aside a decent amount of time for this one.
