Is git checkout deprecated?

Q: I heard that "git checkout" is deprecated? Why? When? What's the reason? What's the replacement?

Short answer

git checkout isn't actually deprecated. It still works, there's no deprecation warning, and it isn't on the list of things slated for removal. What happened is that Git added two newer commands meant to replace it for everyday use, which is probably where the "deprecated" rumor comes from.

URL handling: RFC 3986 vs. WHATWG URL Standard

Two models exist, and they are not interchangeable.

• RFC 3986 / RFC 9110 / RFC 6455: a grammar plus optional normalization steps (RFC 3986 §6). Invalid input is undefined.
• WHATWG URL Standard (https://url.spec.whatwg.org/): a parser (§4.4) that turns any string into a URL record or failure, and a serializer (§4.5). There is no separate "normalization" phase; what the parser does is the normalization. Its stated goal is to obsolete
