It can be normal for the boiler to cycle more than once on pressure before the room temperature satisfies the thermostat. You don't want it to happen in a very short time. If it changed, the stat's anticipator may have been set to longer, some radiators shut off, firing rate increased, air venting slower or closing sooner, weather colder, or heat loss of bldg increased, or pressure settings lowered. If before it was borderline of almost hitting pressure first, than you might have had a slight change.
