NEW YORK (AP) — Amid chatter of “Facebook fatigue,” real or imagined, the world’s biggest social networking company is getting ready to unveil a new version of News Feed, the flow of status updates, photos and advertisements its users see on the site.

Facebook Inc. is hosting an event at its Menlo Park, Calif., headquarters on Thursday to show off “a new look for News Feed.” The company offered no other details on what the changes will be in an invitation sent to journalists and bloggers. It will be Facebook’s second staged event at its headquarters since the company’s May initial public offering. The company unveiled a search feature at the first one in January.
