What has happened to \setupfootnotes?

\setupfootnotes defines [textcolor=] although in the wiki just below this the example has [color=] instead.

But neither of these do color the footnote text. As the reset of the footnote numbering by chapter with way=bychapter doesn't work either, though advertised in the wiki, I really fear there is something amiss here.

I am the one who is mistaken or are some reparations needed?
