We've released a new version of the Facebook plugin with new code to manage author Facebook accounts and permissions, improved management of an associated Facebook Page, improved Open Graph protocol media extraction, and general code cleanup.
Author Facebook accounts
Site authors should continue to manage the connection between their WordPress account and their Facebook account through the WordPress profile screen. Facebook now adds its own section to the profile screen to display currently granted permissions and prompt for new publishing permissions if not already granted.
Authors may now choose to associate their Facebook account for a Facebook-specific byline without granting permission to publish articles to their Facebook Timeline. The Facebook plugin will output special markup with each post to attribute an article to the author's Facebook identity.
Developers: if you previously tapped into login.php for custom code extending the Facebook plugin's behavior your code may no longer function as expected.
Associate a Facebook Page
If you previously experienced issues publishing to a page try removing the page from your site on the Facebook Social Publishing and saving the page again to generate a fresh access token to be used to post to the Facebook Page on your behalf.
App access tokens in more places
Version 1.5 replaces some requests made using the Facebook SDK for PHP with an active user session to app access token requests not requiring an active user session. These new permission checks and other calls should improve performance and availability of plugin features in non-browser environments such as XML-RPC.
New Open Graph object types by post format
A post using the video post format is now auto-classified as an Open Graph object type of video. You may override the Open Graph object type early in the Open Graph protocol generation process using the new
facebook_og_type filter. This filter also affects Open Graph actions for the object, overriding the
news.publishes action associated with an Open Graph article for sites with an approved Open Graph action.
Open Graph protocol media discovery
The Facebook plugin will attempt to extract video and audio attachments for video or audio post formats respectively.
The plugin now includes a custom font to display a vector-based icon in the administrative interface menu. The custom font should inherit administrative theme styles including hover and active coloring similar to MP6 dashicons.
New setting for child-directed sites
Removal of option migration scripts
The Facebook plugin no longer contains migration scripts to maintain options set in plugin versions 1.0 and 1.1.x. Removal of these files improves plugin stability and removes an extra option request with each load of the administrative interface.
