The new Facebook app is a vast improvement over the Windows 8.1 app, providing many features Facebook users will expect such as comment replies, photo tagging, and mood-based status updates. The new app more closely follows the modern Windows design language, while sporting Facebook's unmistakable color palette.
While clearly still in development, the beta app appears to be very stable as of writing. I've been able to post updates, pictures, comments, and replies without any issues. It also delivers (sadly, unactionable) notifications to your action center and photos to your live tile.
The new app also supports sticker pack downloads for use in comments, and even the new "like" options Facebook introduced recently. The app works well with both touch, and traditional mouse and keyboard setups, utilizing mouse hovering in place of a long-touch press for certain menu elements.
Facebook for Windows 10 doesn't support messaging within the app. Similar to Facebook's mobile apps, clicking on the messaging pane at present loads up Messenger.com in your default browser. We know that Facebook is working on a new Universal Windows App for Messenger, so it's fair to expect that messaging notifications will link to that app for users who have it installed in the future.
The Facebook app for Windows 10 doesn't support media queries for smaller screen sizes, such as mobile phones. At least for now, it appears that this new app isn't intended to replace the Microsoft-developed Windows 10 Mobile Facebook app as a cross-platform Universal Windows application.
Although a few users (German, Brazil, UK, etc.) have been able to sign in (almost by chance), it doesn't seem as though Facebook is moving into a fully open beta just yet. Feel free to try the download link below, and let us know if you're able to access it in the comments!
