In WP 2.0.2 you could specify "Show at most n (days | posts)" under Options > Reading.
In 2.1 this has been changed to only accept "Show n posts"
I'm using WP as a CMS for a weekly newspaper and we post all of our stories once a week. "Show at most 1 day" worked perfectly for us, because it would show only posts from the current issue (posted all on one day since we're a weekly).
Can anybody help me get this back? I've tried changing the values of what_to_show by hand in the database and it doesn't work. We really need this function to work before we can upgrade to 2.1
