 * yt-dlp's sanitization of invalid characters in filenames is different/smarter than in youtube-dl. You can use `--compat-options filename-sanitization` to revert to youtube-dl's behavior
 * yt-dlp tries to parse the external downloader outputs into the standard progress output if possible (Currently implemented: [~~aria2c~~](https://github.com/yt-dlp/yt-dlp/issues/5931)). You can use `--compat-options no-external-downloader-progress` to get the downloader output as-is
 * yt-dlp versions between 2021.09.01 and 2023.01.02 applies `--match-filter` to nested playlists. This was an unintentional side-effect of [8f18ac](https://github.com/yt-dlp/yt-dlp/commit/8f18aca8717bb0dd49054555af8d386e5eda3a88) and is fixed in [d7b460](https://github.com/yt-dlp/yt-dlp/commit/d7b460d0e5fc710950582baed2e3fc616ed98a80). Use `--compat-options playlist-match-filter` to revert this
+* yt-dlp uses modern http client backends such as `requests`. Use `--compat-options prefer-legacy-http-handler` to prefer the legacy http handler (`urllib`) to be used for standard http requests.
 
 For ease of use, a few more compat options are available:

+Override urllib3's behavior to not convert lower-case percent-encoded characters
+to upper-case during url normalization process.
+
+RFC3986 defines that the lower or upper case percent-encoded hexidecimal characters are equivalent
+and normalizers should convert them to uppercase for consistency [1].
+
+However, some sites may have an incorrect implementation where they provide
+a percent-encoded url that is then compared case-sensitively.[2]
+
+While this is a very rare case, since urllib does not do this normalization step, it
+is best to avoid it in requests too for compatability reasons.
