"Starting today, you will be able to download an expanded archive of your Facebook account history. First introduced in 2010, Download Your Information lets you get a copy of what you've shared on Facebook, such as photos, posts, messages, a list of friends and chat conversations. Now you can access additional categories of information, including previous names, friend requests you've made and IP addresses you logged in from. This feature will be rolling out gradually to all users and more categories of information will be available for download in the future. Download Your Information is available from your Facebook Account Settings."
