Google has added new search-based features to Google News, which ended its three-year beta test yesterday.

Google aggregates news stories from around the web and groups them into topic-based collections of articles.

The final version of the service continues to allow users to sign up for customised news headlines through the service's Personalized Search. If a user signs up for Personalized Search, Google News will recommend headlines based on news stories a user has read in the past. Recommended headlines will appear whenever a user signs in to his or her Google Account. These results will appear in the left column of Google News, but users also can get a full page of recommended stories by clicking on the section in which they are interested, she said.

Google also has added a feature that displays the most popular recent stories on whatever edition of Google News the user is viewing. A link to a listing of the most visited stories appears beneath subject-area links, such as World, Business and Sci/Tech, on the left side of the main page.
