That's great news if Cambridge no longer requires 24H PPR .... are you sure? my 2019 Pooleys still says 24H needed, makes it moderately useless as an airfield.
Correction: I've just rung them. Apparently officially you do need the 24H but if it's just a VFR arrival it's ok if you ring them before you depart. Better .... but still a bit daft IMHO.
