Starting in Chrome 68 on Android, the Add to Home Screen behavior is changing to give you more control over when and how to prompt the user. If your site meets the add to home screen criteria, Chrome will no longer automatically show the add to home screen banner. Instead, you'll need to call prompt() on the saved beforeinstallprompt event to show the add to home screen dialog prompt to your users
Starting in Chrome 68, 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.
Desktop progressive web apps can be 'installed' on the users device much like native apps. They're fast. Feel integrated because they launched in the same way as other apps, and run in an app window, without an address bar or tabs. They're reliable because service workers can cache all of the assets they need to run. And they create an engaging experience for users.
With Chrome 58, Progressive Web Apps are more immersive with display: fullscreen. IndexedDB 2.0 is now supported and sandboxed iFrames get more options. Pete LePage has all the details and how you can use these new developer features in Chrome 58.
With Chrome 57, you can now use display: grid for grid based layouts, use the media session API to customize the lock screen and notifications with information about the media being played, and more. Pete LePage has all the details and how you can use these new developer features in Chrome 57!
