Nissan frequently updates their ROMs for various mysterious reasons. Uprev just adds support for tuning the updated files as they encounter them.

If you want to know exactly what was changed between revisions or why, you'll have to ask Nissan. The information might be explained in a TSB somewhere, but good luck linking a specific ECM update to a specific TSB.
