I just updated it and haven't checked anything yet, but the update states this:
Improved multitasking usability. - Added a three-split view function on the multi-window. - Added a switching function between pop-up view and split screen view by long pressing. - Added a function to open a split screen by dragging the screen. • Improved Edge panel usability. - Added a Pin feature to pin apps to the Edge panel. - Changed the background screen so that it is not blurry when the Edge panel is on. • Supports Labs feature. • Added a function to remaster desired photos.
