Facebook Home also now officially supported on Nexus 4 and Galaxy S4.
Updates to Facebook and Facebook Messenger tonight have brought out a new feature and new device support across the apps. First up is the Facebook app itself, which added a new lock screen option in the settings to show a Facebook Home-like lock screen with status updates from your friends without replacing your entire launcher with Home. To enable it, head to the Facebook app and hit the settings, then scroll down to "Use as Lock Screen" and give it a moment to enable.
The update also added official Nexus 4 and Galaxy S4 support for Facebook Home, which users have been using pretty successfully unofficially for a while now. On the Messenger side, the app update added Chat Heads functionality for more devices — presumably on the lower end as the update specifically named the Galaxy Y and HTC Wildfire.
We're seeing the Facebook app update on our devices while enrolled in the official beta program, but apparently the update is expected to roll to all users starting today. Grab an update to the Facebook app proper at the Play Store link above, or get the Messenger update here.
