Add to Home Screen changes #
If your site meets the add to home screen criteria, Chrome will no longer show the add to home screen banner. Instead, you're in control over when and how to prompt the user.
To prompt the user, listen for the
beforeinstallprompt
event, then, save the event and add a button or other UI element to your app to indicate it can be installed.When the user clicks the install button, call
prompt()
on the saved beforeinstallprompt
event, Chrome then shows the add to home screen dialog.Chrome Version Release Notes
To give you time to update your site Chrome will show a mini-infobar the first time a user visits a site that meets the add to home screen criteria. Once dismissed, the mini-infobar will not be shown again for a while.
Changes to Add to Home Screen Behavior has the full details, including code samples you can use and more.

Page Lifecycle API #
When a user has a large number of tabs running, critical resources such as memory, CPU, battery and the network can be oversubscribed, leading to a bad user experience.

If your site is running in the background, the system may suspend it to conserve resources. With the new Page Lifecycle API, you can now listen for, and respond to these events.
For example, if a user's had a tab in the background for a while, the browser may choose to suspend script execution on that page to conserve resources. Before doing so, it will fire the
freeze
event, allowing you to close open IndexedDB or network connections or save any unsaved view state. Then, when the user refocuses the tab, the resume
event is fired, where you can reinitialize anything that was torn down.Check out Phil's Page Lifecycle API post for lots more detail, including code samples, tips and more. You can find the spec and an explainer doc on GitHub.
Payment Handler API #
The Payment Request API is an open, standards-based way to accept payments. The Payment Handler API extends the reach of Payment Request by enabling web-based payment apps to facilitate payments directly within the Payment Request experience.
As a seller, adding an existing web-based payment app is as easy as adding an entry to the
supportedMethods
property.Chrome Release Notes 68 Catalina
If a service worker that can handle the specified payment method is installed, it will show up in the Payment Request UI and the user can pay with it.
Eiji has a great post that shows how to implement this for merchant sites, and for payment handlers.
