I was Pilot Flying (PF). Approach controller assigned us 180 KIAS to (the 7 mile fix) which we complied with. Called for gear down at the fix and normal flap extensions and the before landing check which was performed normally. At 500 HAA called '500 to go' and Pilot Monitoring (PM) responded appropriately. On landing rollout I heard another flight being assigned a speed to (the 7 mile fix) and realized we were still on the approach frequency. I also realized that the speeed assignement was the last transmission we had received from approach; that is; they did not hand us off to tower. As soon as the Captain (CA) took the flight controls below 80 knots I switched to Tower and we were issued a hold short instruction for the parallel runway and asked our gate. No mention was made of landing clearances and the flight was completed uneventfully. The landing runway was clear and no conflicts had occurred.This (early morning) flight was the first flight we had performed using the all new SOPM and checklists. We had made several minor errors earlier in the flight as we used the new procedures and checklists. The new procedures and checklists were a significant source of distraction and confusion during all phases of this flight except cruise. I attribute our both not noticing that we had not been handed off to Tower and that we had not heard a landing clearance to the general air of newness; unfamiliarity and distraction caused by the new procedures and checklists that we were using for the first time on this flight.We were both being methodical and diligent as we used the new SOPM and checklists; and had discussed how we would do that earlier in the trip - not hurrying; and stopping if necessary if unsure. This is probably what all flight crews are doing on this first day of these new procedures; callouts and checklists. We had both read the new SOPM and checklists cover to cover during this trip and spent several hours discussing them.  Besides practicing the new flows; callouts and checklists first in an FTD or simulator I'm not sure what else we could do to avoid recurrences of events of this nature when trying to suddenly adapt to all new procedures during regular line flying.
CRJ-700 First Officer reported landing without a clearance; citing distraction of new checklist procedures as contributing.
