zwift-hotkeys v21 is a bug fix for the Exit button shortcut – update if you already installed v20.
Otherwise the improvements are the same as in v20:
- New shortcut: Ctrl+x for Exit (in the start screen)
- New shortcut: Ctrl+Shift+W for opening the route description in a browser (while riding)
- Bug fix for detecting the Paused screen
