Narrative:
We performed the shutdown checklist and received the 'chocks in' signal from the ground crew. I then released the parking brake to improve brake cooling. After a few minutes; while passengers were deplaning and the ground crew still unloading the cargo compartment; the aircraft started rolling forward. While maintenance was doing their aircraft inspection; they were the first to notice the aircraft starting to roll. A mechanic ran to the nose wheel and reinstalled the aircraft chock. The aircraft rolled about three feet forward before being re-chocked. The only passengers that noticed the aircraft movement were those on the stairs. No passengers; crew or ground personnel were hurt. The aircraft did not hit anything; so no aircraft damage. It was noted by maintenance that the chocks were new and this was the first time using them. The chocks appeared slick and not as grippy as the older chocks. I suggest making sure the new chocks are certified for our size aircraft. Unless absolutely necessary; I will keep the parking brake set until deplaning and ground services are complete.
