 Some of yt-dlp's default options are different from that of youtube-dl and youtube-dlc:

-* yt-dlp supports only [Python 3.8+](## "Windows 7"), and will remove support for more versions as they [become EOL](https://devguide.python.org/versions/#python-release-cycle); while [youtube-dl still supports Python 2.6+ and 3.2+](https://github.com/ytdl-org/youtube-dl/issues/30568#issue-1118238743)

 * The options `--auto-number` (`-A`), `--title` (`-t`) and `--literal` (`-l`), no longer work. See [removed options](#Removed) for details
 * `avconv` is not supported as an alternative to `ffmpeg`
