I asked in a previous post if what was "Recent posts" is now "New Posts", but it doesn't look like it is. The difference is that if you post in a thread, it doesn't show up in New Posts. I always used Recent Posts because it was the quick way to see the most recent everything, whether or not you posted in them. Is there a way this functionality can be restored?
So far, we see your post in the sidebar Latest Posts,
and in Recent Posts, under What's New.
