WordPress is_front_page() function
New for version 2.5, this function should clear up confusion when using a static page as front page - 2.3 and lower had trouble here when using is_home()
is_front_page() returns true when the main blog page is being displayed and the Settings > Reading > Front page is set to “Your latest posts”,
or
when Settings > Reading > Front page is set to “A static page” and the “Front Page” value is the current Page being displayed.
