Google Chrome has been updated to version 28 (28.0.1500.71) for Windows and Mac and brings a rich notification center (only on Windows) among other features and improvements. The Mac version is also said to be receiving the notification center, but for now its reported that “Mac is coming soon” without a specific date.You can allow the update to be installed automatically in the background through the browser's built in silent updater or manually check for it by heading to 'About Google Chrome' on your menu or google.com/chrome.
Google Chrome version 28 is also the first build expected to run the Blink browsing engine instead of WebKit. You can head over to chrome://version/ on the browser which will display the Blink engine version.
Google says that they have “... designed these notifications to be beautiful, useful and engaging”. Notifications from apps and extensions can be formatted to display text and images, as well as include actions directly inside the pop-up.
This extends the ability to Chrome app developers to add these rich notifications to their own applications which allow users to interact directly with the app through the notifications, even if your web browser is closed. Sof if you head away from your computer for some time, you can easily get back to your missed notifications. And if you don’t want to deal with them at all, you can easily disable them from within the settings.
The Linux version of Chrome was updated to version 28 (28.0.1500.45) back on June 17, ahead of the other desktop platforms and likely closer to Chrome OS releases. The minimum requirements for Linux distributions have also been updated and Ubuntu 12.04+, Debian 7+, OpenSuSE 12.2+, and Fedora Linux 17+ are now required to run Chrome.
