Google announced on the official Google News blog three new features coming to the U.S. edition of the site, including: new larger images on the main news page; real-time updates that will cover only the latest content; and new integration with Google+ content.

The realtime coverage page provides access to “every news story as soon as they become available to Google News.” The page will also include “Google+ Discussions” to the right, which will even display on the refreshed News homepage. The discussions will only appear to those signed into to Google+ and will consist of comments from journalists, politicians, and those in your Circles currently discussing breaking news.

The Google+ discussions, new realtime coverage page, and larger images will roll out over the next week, but you can upgrade now (here). Google also provided the following instructions to turn off the Google+ integration:

if you prefer your Google News to contain just news stories and no Google+ posts, you can either log out of Google or turn off the display of Google+ posts via the Google News settings page.
