Rich Notifications are another new Chrome feature. Chrome already supported basic notifications, but with the new notifications users can be shown, and can interact with, tips and information outside of the browser. For example, a pop-up window in the Windows task bar can inform users when a new email arrives. Notifications can contain pictures, buttons and URLs as well as text. The notifications are handled by a notification center outside the browser, which not only allows the information to be displayed without a running browser but also serves as somewhere a user can consult to see what notifications they have missed.
Rich Notifications replace HTML-based notifications in the Chrome extensions: HTML-based notifications are no longer supported in version 28. Comprehensive instructions for developers are available. At the moment, Rich Notifications only work in Chrome OS and Windows – support for Mac OS X and Linux is said to be coming.
Version 28 also closes various security holes including a richly rewarded use-after-free issue with network sockets and a well-rewarded fix to a HTTP/SSL man-in-the-middle attack. Other rewarded bugs included two use-after-free issues in input handling and resource loading, plus an out-of-bounds read in SVG, all found by Chrome bounty regular miaubiz, a screen data leak through GL textures with Windows and NVIDIA cards, and a lack of entropy in renderers.
The updated browser is available to download for Windows, Linux and Mac OS X or, for existing users, will arrive automatically. Chrome has also seen its Flash player updated to version 11.8.800.97 as noted in Adobe’s patch day.
