Manual talk:Hooks/ChangesListSpecialPageQuery

Dear All.

I don't get it. The page https://www.mediawiki.org/wiki/Manual:Hooks/SpecialRecentChangesQuery links to https://www.mediawiki.org/w/index.php?title=Manual:Hooks/ChangesListSpecialPageQuery&action=edit&redlink=1 because SpecialRecentChangesQuery is deprecated in version 1.24. But, the new ChangesListSpecialPageQuery doesn't seem to be described in any way. Why is that?

It seems to me that someone have decided that this hook should not be used anymore. They created a substitute without describing it's use. Am I missing something obvious?

Regards
