Other

• Check content open issues to see if any pertain to the subject matter. If there are any that can be closed because of the work, do so. If there are any that can be fixed relatively quickly because of the knowledge from completing this issue and you have time, feel free to go ahead and fix them.
• Check if glossary updates are required for the feature you're documenting - whether an existing term needs to be updated or a new term should be added.
• Check if BCD update means that content pages need to have experimental markup removed or deprecated markup added (front matter tags and macros).

This has no MDN impact: https://bugzilla.mozilla.org/show_bug.cgi?id=1603699#c13

@hamishwillee I was faced with a situation where the absence of information became relevant, in foxyproxy/browser-extension#120 (comment) .
There was no information on Firefox 122 for developers either.

@erosman Thanks. I asked this question in https://bugzilla.mozilla.org/show_bug.cgi?id=1603699#c13

What is the direct impact of this change to website-developers? What should they do differently because of this?
Can you explain what documents we might need to touch?

Same question to you - what would have made this visible to you? Perhaps an update to add a note to the constructor browser compatibility entry here: https://developer.mozilla.org/en-US/docs/Web/API/URL/URL ?

It could say something like "From version 122 the host and port are parsed for unknown protocols/schemes" ?

It could say something like "From version 122 the host and port are parsed for unknown protocols/schemes" ?

Or maybe... "Prior to version 122, host, hostname, & port were not returned for unknown protocols/schemes."

Thanks, I like that more. BCD addition here - mdn/browser-compat-data#22079 (made to URL() this is where the URL with non standard schema would be passed in)
