The latest version of the Facebook plugin for WordPress introduces a new Mentions Tagging interface, speeds up administrative site access, better supports unattended posts to Facebook such as XML-RPC mobile posts or an editor taking a contributor's post live, and adds support for Facebook account linking from the WordPress edit profile page.
Mention friends and pages in an optional custom message published to your Facebook Timeline with a post. Press the "@" key to begin a search and select a result. Press the "esc" key to end a search attempt. Facebook will special syntax to a profile or page link and send a Facebook notification to your friend.
hello @" would render as
hello Mark Zuckerberg on Facebook and link to Mark Zuckerberg's profile. If you are friends with Mark Zuckerberg he would receive a Facebook notification and possibly a new story on his Timeline (if his privacy settings allow)
Mentions Tagging replaces the previous friend tagging and pages tagging meta boxes. Mentions previously displayed above and/or below your post will no longer appear. Mentions Tagging affects only the custom message sent to your Timeline. Facebook no longer supports the old mentions API as of February 6, 2013.
Disable publishing to Facebook on a per-post basis
The custom message composer for an author's Timeline or Facebook Page now includes a checkbox to disable sending a post to Facebook when it becomes public. Publish flows unable to check this checkbox should be automatically published; these publish actions will not receive the same explicit sharing property as post published with the post meta box present and selected.
App Access Token Requests
The plugin verifies your Facebook application identifier and secret with Facebook's servers when saved through the settings page by exchanging these two pieces of information for a Facebook application access token. Future requests from your server to Facebook's servers not requiring an active Facebook user session are sent using your Facebook application's access token. Facebook servers verify your requests against permissions granted to your application by your users and process the new request on behalf of your application.
Authors may take a post public without an active Facebook browser session including posts from mobile clients.
Associate your WordPress account with your Facebook account from the edit profile screen
A WordPress user with the
edit_posts capability can now associate his or her WordPress account with a Facebook account and grant your application publish permissions from his or her edit profile page. An author may associate a Facebook account while opting-out of publishing posts to his or her timeline through a publish permissions checkbox.
Plugins and themes relying on a previous variable state of the Facebook plugin for WordPress may not function as expected.
The switch to an app access token reduces reliance on an active Facebook user token, removing the need to extend the token until it is needed. If you previously relied on the Facebook plugin to extend your users' Facebook tokens you should directly extend these tokens in your code.
If your code referenced a stored copy of the initialized Facebook PHP SDK, most likely the
