Default [Q] Verizon Note 3 NC4 Firmware Difference?

What exactly was updated or changed in the newest N900VVRUCNC4 firmware update for the Note 3? I'm asking because I'm on NC2 and I'm wondering if it's worth the time to update that firmware. I updated to NC2 originally in order to run KK.

Is it superior to the NC2 in terms of performance?
