(Telecompaper) Facebook announced a number of changes to its social network and apps at the first day of its F8 developers conference, in line with its recently announced increased focus on messaging and privacy. Facebook itself will be redesigned to take a greater focus on social aspects like groups over the news feed, while Messenger is getting a new, lighter app as well as a desktop version. While no major hardware was announced, Facebook did announce the start of pre-orders for the Oculus Quest and Rift S and plans for an enterprise VR offering.
