The redesigned "Reset this PC" and "Go back to earlier build" dialogs, respectively implemented in builds 25231 and 25247 but later removed altogether in build 26085, have been re-implemented. These changes are disabled by default, but can be activated manually by enabling the 41598133 and 41670003 velocity staging keys.
A new option has been added to the advanced camera configuration dialog in the camera properties page under Bluetooth & other devices > Camera for choosing a specific camera resolution.

It's also disabled by default, but can be activated manually by enabling the 49575624, 50292326 and 52142480 velocity staging keys.
