This section of the documentation page leads to confusion. If the Github is saying right, then "An integer" like 3000 works.

Yes, it would work if there's a NS 3000 on the wiki. On mediawiki.org there isn't, so it doesn't appear.

The mediawiki.org api generated help page is not going to be representative for your own wiki.

I don't think there is a bug there.

Other things missing from the documentation page MediaWiki API help are:
&hidepageedits=1
&hidelog=1

ChangesListSpecialPage adds those two parameters. They need adding/documenting in ApiFeedRecentChanges I guess

&hideWikibase=1

Obviously an issue with MediaWiki-extensions-WikibaseClient, not MW core. Probably needs to do something with the APIGetAllowedParams hook to add them

@Reedy: We also had the confusion over &namespace= accepts multiple values seperated by ; on Special:RC but the api doesn't. Could the api accept multiple namespace values?

Probably

Just needs a ApiBase::PARAM_ISMULTI => true, adding to ApiFeedRecentChanges::getAllowedParams() in the namespace array (like other API modules do) if the underlying class can do multiple NS fine. Should be enough easy to test.

Separate bugs should be filed for separate issues. There's at least 3 different issues (depending on how you count) here, and 1 is seemingly invalid.

@Reedy: tasks created!

Hi, What is the next step on solving / improving / updating this. Is someone working on it or is in hiatus?
