This new build is fairly ahead of the current build 10080 currently available to Windows Insiders and has a couple of new features and tweaks.
The dialler and clock pivots are now swipeable
The app search button present in the app list is now a search bar
Devices which have HD resolution or higher can now show a split screen settings view when turned to landscape
The Store Beta and general UI and third-party app quality is now smoother and more responsive than previous builds.Hope we won’t have to wait much longer to launch its latest public preview build of Windows 10 Mobile to Windows Insiders.
