Whats New in Chrome 76

In Chrome 76, Google added new supports for:

  • prefers-color-scheme media query, bringing dark mode to websites.
  • An install button in the omnibox to make installation of Progressive Web Apps on desktop easier.
  • Preventing the mini-infobar from appearing on Progressive Web Apps on mobile.

Faster updates to WebAPKs

When a Progressive Web App is installed on Android, Chrome automatically requests and installs a Web APK. After it’s been installed, Chrome periodically checks if the web app manifest has changed, maybe you’ve updated the icons, colors, or changed the app name, to see if a new WebAPK is required.

Starting in Chrome 76, Chrome will check the manifest more frequently; checking every day, instead of every three days. If any of the key properties have changed, Chrome will request and install a new WebAPK, ensuring the title, icons and other properties are up to date.

Dark mode Support
Many operating systems now support a dark mode, or dark theme.

The prefers-color-scheme media query, allows you to adjust the look and feel of your site to match the user’s preferred mode.
