First launch: these installers are not notarized on macOS or code-signed on Windows yet, so your system will ask for confirmation once. On macOS, right-click the app and choose Open. On Windows, if SmartScreen appears, choose More info and then Run anyway. The SHA-256 list below lets you verify every file.
