Most likely more bug fixes. Maybe fixes eco boost and more RAM/XMP fixes.
That's very odd. It is the same BIOS number as last time. Either they just cleaned up the web page and edited the date 1404 was released to make it look newer than it is, or they really screwed up and released another BIOS with the same version number.
