New in Chrome Android

The following features are now available in Chrome Android:

  • Beacons: The navigator.sendBeacon() method asynchronously sends an HTTP POST request with a limited amount of data, typically for app state, events, and analytics data. The one-way beacon is guaranteed to be initiated before the browser unloads the page, but the sender does not get to handle the response.
  • Classes: Classes are an object-oriented syntax for JavaScript prototypes.
  • Fetch: The fetch() method makes asynchronous HTTP requests.
  • Notifications from service workers and installed apps: Notifications via service worker registration's showNotification() method, sent from installed web applications (for example, saved to the Home Screen on Safari for iOS), show a message to the user, typically using the notification system of the host operating system.
  • tab-size: The tab-size CSS property sets the width of the tab character.
