The senior vice president of Microsoft Teams announced that Teams would be moving to their own Edge Webview2 Rendering Engine ditching Electron for seeking performance gains. It is marketed that Teams would consume 2x less memory as a result of the transition. It would be called Teams 2.0 and might ship with Windows 11 in late 2022.
Sigh, I thought they were going to move to Qt or something. Should have known better.
