Using <h4> and the likes to make headings without generating entries in the table of contents is broken, and now does generate headings. See http://en.wikipedia.org/w/index.php?title=Wikipedia% 3AHow_to_edit_a_page&diff=18547351&oldid=18472209 for information on the change, which coincided with 1.5. Even if this is an intended change, there should be a way to keep headings out of the ToC.
