Yeah, I'm on 2164 here and the most recent files only appear in the Ctrl-P list if they're open. When I close them, they disappear from the menu and the list is sorted alphabetically as it always was.

If I start typing the first few letters of a file that was recently closed, it jumps to select that file, even if there are several that named similarly, but that's not as useful as having a list of the most recently opened files right there at the top of the list.
