I landed at Santa Monica yesterday. I landed on Runway 21; and turned right to exit the runway to taxi to the FBO. I was pretty impressed with myself that I got stopped in time to quickly dart into the FBO; landing in a record short distance.Unfortunately for me; they have changed the procedures at SMO since the last time that [I] was there. Now; they have specific painted taxiways that they want you to follow.Of course; there's nothing painted to show where NOT to go. I'd suggest striped lines; or green paint in the 'forbidden' areas. San Diego airport has green paint; for example.I'm not aware of any NOTAM concerning the new taxiway arrangement; however in the AFD is the following notes:'ACFT MUST NOW EXIT THE RWY AT DSGND CONNECTOR TWYS. THE CONS RWY EXIT SYS IS NO LONGER AVBL.'
GA pilot reported a possible taxiway deviation and reported not being able to find NOTAMs describing taxi procedure changes at SMO airport.
