Badging for App Icons
The Badging API allows installed web apps to set an application-wide badge, shown in an operating-system-specific place associated with the application, such as the shelf or home screen. Badging makes it easy to subtly notify the user that there is some new activity that might require their attention, or it can be used to indicate a small amount of information, such as an unread count.

Fresher service workers, by default
HTTP requests that check for updates to the service worker script will no longer be fulfilled by the HTTP cache by default. This works around a common developer pain point, in which setting an inadvertent Cache-Control header on your service worker script could lead to delayed updates. Also, updates to imported scripts can trigger the service worker update flow.
