STM32F4 Unused pins

Is there any clear recommendation from STM how should the firmware configure unused untied GPIOs? In past STM32F1 controllers we used to configure them as output '0' in order to avoid noise (our environment is very noisy) but is there a need for this with the new STM32F4 family?
