Android 8.0 Oreo released officially
I gathered the most meaningful updates for you. Let's see what's new it brings to us!

Background limits
New limits on implicit broadcasts, background services and location updates. Read more: one, two.

Notification channels & badges
Grouping notifications together by their type. Users can control how things are displayed on a per-channel basis now. Read more.

Picture in picture
Shrink the view of an app into a small secondary overlay that can be positioned by the user at run time. Extremely useful after terrible multi-window mode we had before. Read more.

Adaptive icons
Now icons contain foreground image, background and a mask. Developers (we!) got the build in tool for Android Studio to create adaptive icons. How do they work?

Font resources in XML
Finally, fonts are the part of the Android native ecosystem. Now they are so easy to use as colors. We can use them in styles and Google even provide a bundle of all fonts out from the Android Studio. How to use them?

Autofill APIs
Autofill that I used so much on the web now migrated to mobile apps. Passwords stored and managed centralized and the user can choose which credentials to use. Read more.

WebView enhancements
Multi-process mode for WebView components, better ways to terminate a web view window, determine the priority of rendering a web view, Google Safe Browsing API. How to check URLs via Google Safe Browsing API?

Instant App support
Of course, we were waiting for this. Opens in 1 click, there is no install time. The existing apps require some changes to become really "instant". Getting started: step-by-step guide.

Devices that will get the update first: Pixel, Pixel XL, Nexus 5X and 6P.
