New in Chrome 73

In Chrome 73, we’ve added support for macOS, bringing support for Progressive Web Apps to all desktop platforms – Mac, Windows, Chrome OS and Linux, as well as mobile, simplifying web app development. We’re working to add new web platform capabilities that give you access to things like the file system, wake lock, adding an ambient badge to the address bar to let users know your PWA can be installed, policy installation for enterprises, and plenty more. Constructable Stylesheets, new in Chrome 73, gives us a new way to create and distribute reusable styles, which is particularly important when using Shadow DOM.
