Edge-to-edge screen share views even in windowed mode. Before, there was a significant difference between being a guest in a screen share with a full screen window vs. a regular window. In v7, we've unified both window experiences, so you always get the entire screen share view in its own window, plus a secondary window with all the call controls in it. And if you keep the secondary window close to the primary one, they'll be docked, so they'll move together.
There are also numerous other bug fixes, notably around trading control between host and guest.
