We've released some major changes to the Facebook plugin for publishers interested in publish to Timeline and Comments Box functionality.
Setting up a news-specific Open Graph action has been a major hurdle for publishers interested in publishing to Facebook. The plugin now supports a basic publishing endpoint roughly equivalent to the Facebook Feed Dialog for publishers just getting started with the Facebook plugin. Once a publisher has successfully setup an Open Graph publish action you may enable publishing Open Graph action publishing through the Social Publisher Settings in your WordPress administrative interface.
Upgrade note: If you previously setup a Publish action with User Messages, Tags, and Explicitly Shared capabilities you should visit the Social Publisher Settings page after upgrading your plugin to continue to take advantage of special distribution and story highlighting features on Facebook.
Comments Box has moved from just after your post content to a full replacement for your theme's comments template functionality. Posts with existing WordPress comments will now display those comments followed by the Comments Box social plugin. You may customize many pieces of the comments display using actions and filters similar to WordPress default comments functionality; See "Custom actions & filters" under "Other Notes" in the plugin listing page for more information.
If you previously applied custom CSS rules to the Comments Box social plugin you may need to reapply styling to the new comments template placement.
