and when adjusting that

Hi, what does "adjusting" mean exactly?

but it seems like the change made for 1.40 is already broken for 1.41.

Which "change made for 1.40" exactly, in which codebase? https://www.mediawiki.org/wiki/Extension:ConfirmEdit#Turnstile says that Turnstile requires at least MW 1.41... not sure I can follow.

Turnstile is mentioned to work as of MW 1.41 (which I have), but requiring the master branch of ConfirmEdit - that is locked to MW 1.42 in extension.json though and hence conflicting (will throw 500 on wiki). With adjusting that I meant changing this requirement in extension.json to MW 1.41, to see if it works.

Which it does not, as then "Missing Captcha" will appear as error in Visual Editor when trying to send a change. Given Confirm Edit 1.42 master is likely not suitable for MW 1.41 I hence manually applied the patchsets from the implementation task (https://phabricator.wikimedia.org/T319068) and applied them to MW 1.41 bundled ConfirmEdit, and the issue described here is the result, e.g. Turnstile does not work in MW 1.41 - and hence likely not in MW 1.42 either, as of that task the implementation was originally made and tested for MW 1.40, but merged many months later to be released in MW 1.42.

The request behind the report is to either get Turnstile working on MW 1.41 or confirming if it actually does work on MW 1.42 and changing the wiki entry to reflect it needs MW 1.42, not MW 1.41. The former would be preferable for me personally, but potentially not what you want :)

TL;DR:

• Wiki states that Turnstile can be used on MW 1.41 with Confirm Edit master branch, but Confirm Edit master branch requires MW 1.42
• Changing that via extension.json leads to Visual editor on sending throwing an error "Missing captcha"
• Applying the implementation patchsets for Turnstile to MW 1.41 bundled confirm edit causes the issue reported here

Turnstile neither works with Confirm Edit 1.41 nor Master 1.42 on MW 1.41. I'm not sure it will work on MW 1.42 either.

https://www.mediawiki.org/w/index.php?title=Extension%3AConfirmEdit&diff=6370896&oldid=6359198 incorrectly marked it as {{MW 1.41|and after}} when it should be {{MW 1.42|and after}}. As it was only added in rECOEfbf6c1c7ea1a: Add Turnstile support, which is only in master. Docs fixed in https://www.mediawiki.org/w/index.php?title=Extension%3AConfirmEdit&diff=6429541&oldid=6429473

The ConfirmEdit wiki page mentions Turnstile being available for MW equal to or higher to 1.41, but requiring usage of the master branch.

Wiki states that Turnstile can be used on MW 1.41 with Confirm Edit master branch

No it doesn't/didn't.

Currently only available in master branch of the extension.

Available in, doesn't mean usage of.

We generally don't backport features like this.

And as per the infobox at the top of the page...

Compatibility policy Snapshots releases along with MediaWiki. Master is not backward compatible.

We'll have to disagree on that one, it saying >= 1.41 (Currently only available in master branch of the extension.) for the average user clearly means it can be used in that version and higher with that branch and that is exactly what I am, not a developer.
The conflict in information to the one in the infobox can barely be on me. Especially given the master branch of many other extensions typically works fine in the released version.

I took the time to test it on MediaWiki master, and it shows the same error picture there, but given the obvious rudeness in your answer it is clear to me that my input isn't desired and I am hence leaving this report.
