CPT-4 codes update

Good evening to everyone!

Could you please tell me how often are the CPT-4 codes and Fee Schedules updated in OpenEMR? I mean if I download the OpenEMR today, what would be the last version of CPT-4 codes and fee schedules in it?
I also wonder what resources can be used to update the codes and schedules regularly and how should I upload them into the system?

Thanks in advance!
