Prominent features of Budgie Desktop 10 include an all-new notification and customization center called Raven, proper support for HiDPI displays, support for multiple panels, proper support for keyboard layouts and keyboard switching, as well as support for multi-monitor configurations.
Furthermore, all the desktop’s settings are now handled by Raven, all the old settings are now being ignored because they contained bad code, there are numerous code optimizations that make the desktop a lot faster then before, and the GNOME Session has been adopted instead of the Budgie Session.
