They secured a place in the Championship after manager Darren Ferguson led them to consecutive promotions in 2007–08 and 2008–09 and spent three of the next four seasons in the second tier, winning a play-off final in 2011 after relegation the previous year.

In 1977–78 the club threatened to go one better until they narrowly missed out on promotion to Division 2 when they drew the last game of the season at champions Wrexham (0–0) when a win was needed to go up.

Progress continued in the league and a play-off place was clinched on the last day of the season despite a 1–0 defeat to champions Brentford.
