A federal judge has ruled that Customs and Border Protection (CBP) must have probable cause before searching a person's devices. This may seem like a Pyrrhic victory because it only requires cause (we know inventing 'cause' is not a stretch) and not a warrant, but it nullifies a concept asserted and enforced by the CBP for some time: that a customs zone is not yet "America" and therefore the Constitution does not apply.
Massachusetts District Judge Denise Casper's ruling on Fourth Amendment grounds establishes that the Constitution does apply to federal agents and American citizens / legal residents regardless of where the stormtroopers think they are.
