The new Phase One P firmware allows you to have more control when used with the Schneider Digital Shutter system. So if you are not using that shutter system, you really will not see any new functions.
But The phase One link I posted says this:

Firmware version 3.3.6/2.5 corrects the following issues on P - Series digital backs:
1. Updated CF handling with all correction made since last P20/P25 release. Includes correct formatting of CF cards larger than 8GB, and failure that occurred when formatting CF card in a FUJI S3 camera after formatting in a P20 or P25 version 3.34 and older.
2. Improved EXIF handling for the Mamiya, the 1/3 step in AFDII is now included.
3. The TTL Flash Adjustment value for the H1 now setup again if the back is re-attached to a H1 camera without being powered off.
4. Compatibility of San Disk Extreme IV CF cards 2, 4 and 8GB
Plus a few minor adjustments to the firmware code of the P - Series backs.

Not new functions but issues with CF cards which IMHO are significant.
