Rotherham United completed their Championship great escape and equalled an unbeaten run set 50 years ago as they held Wolves to a goalless draw at Molineux.
A point was enough to seal the Millers' second-tier safety and extend their incredible unbeaten sequence under Neil Warnock to 11 matches.
The last time a Rotherham side went that long undefeated at this level was back in 1966.
MK Dons lost at home to Brentford to confirm their relegation with Charlton Athletic and Bolton Wanderers.
It was the fifth clean sheet in six away matches for Warnock's men, who moved up to 19th in the table, and Wolves' fourth 0-0 home draw on the trot.
In a slow first half, Rotherham were content to defend and try to hit Wolves on the break, with Grant Ward's pace on the right flank a regular danger
Dave Edwards should have scored for the home side after eight minutes but screwed his low shot just wide and Lee Camp tipped Danny Batth's header on to the bar 14 minutes later.
After the break, Joe Mason and Dave Edwards both found themselves clean through but were thwarted by Camp, while Matt Derbyshire's tested Carl Ikeme with a volley from the edge of the penalty area after Greg Halford's long ball.
Millers right-back Stephen Kelly saved a certain goal with a goalline clearance from Jed Wallace's shot after 73 minutes, but the visitors upped their threat and Derbyshire brought another good save from Ikeme, before Camp touched a Mason shot over the bar.
Rotherham had made one change to the team which had drawn 1-1 with Huddersfield Town in midweek, bringing in Leon Best up front in place of Danny Ward.
Ward had picked up a leg injury and didn't even make the bench.
Sylvain Deslandes headed just wide for Wolves in time added on, but the Millers held on to mathematically confirm what everyone knew when they won 4-0 at stadiummk two weeks ago to open up a nine-point gap between them and the drop zone ... that they'll be a Championship club again next season.
