Aggisi Lumia has revealed that a new Version of the Electron-based Facebook Messenger app is already on the shelves in the Windows 10 Store. Users who pre-empt beta versions will get an experience that approximates the iOS and Android versions. For example, attach a file or select a dark color theme, delete the message and send/use a new emoji.

At the bottom of the software, the new beta version abandoned OSMeta technology in favor of Electron. This means that the app will adopt new features more frequently, alongside iOS and Android versions.
As time goes on, more users will get this update. Unfortunately, the app is currently available only in x64 versions and does not yet support Surface Pro X.
