In Views you can add a field for New Content ... how/where are the settings for how new is new? Eg if I only want nodes created in the last 28 days to appear?

Accepted answer

You can filter the nodes by Post Date to show only those that have been created in the last 28 days. You can filter by a relative date, for example "> -28 days"
