STM32F407G-DISC1 requires PC connection to boot

Recently the STM32F407 discovery board changed part numbers from STM32F4DISCOVERY to STM32F407G-DISC1. The old boards could be powered directly via the 5V pins on the headers, or via a USB wall-wart, but the new boards need to be connected to a PC in order to boot. Is this intended behavior? Is there a solution aside from flashing an older firmware to the STLink chip?
