The second, optional, parameter is the number of the namespace to pass to the recent changes function (0 is the article namespace, 1 is the talk namespace, etc.). Examples:
{{recent changes}}→ Recent changes{{recent changes|Test}}→ Test{{recent changes|Test|0}}→ Test{{recent changes||0}}→ Recent changes
