Gillingham celebrated promotion to npower League 1 after seeing off Torquay United 1-0 thanks to a Danny Kedwell goal early in the second half.
Defeats for Rotherham United and Northampton Town ensured a return to the third tier following a three-year absence after Kedwell volleyed home his 15th of the season in the 48th minute.
Northampton went down 1-0 at Bradford, where Nahki Wells took advantage of a mix-up in defence to score easily in the 23rd minute. The win moves Bradford to within two points of the Play-Offs as Exeter City lost 1-0 at home to Dagenham & Redbridge, with Scott Doe's fifth-minute header the only goal.
Rotherham, sixth but with games in hand on those around them, lost 2-1 at Morecambe as Kevin Ellison scored a last-minute winner for the hosts.
Morecambe got the opener against the run of play through Robbie Threlfall, but a somewhat lucky deflected goal from Alex Revell brought Rotherham level, only for Ellison to snatch it at the death.
Cheltenham Town failed to take advantage of Northampton's defeat and remain fourth after losing 2-0 away to Plymouth Argyle, with Michael Hector's own goal ensuring defeat after Reuben Reid's opener.
At the other end of the table, Peter Murphy's injury-time goal for Accrington Stanley kept York City in the relegation zone following a 1-1 draw at Bootham Crescent.
Accrington Stanley's were about the only fans singing among those near the bottom of the table, with AFC Wimbledon losing 1-0 away to Bristol Rovers and Barnet going down 2-0 at home to Chesterfield.
Fleetwood Town had a miserable afternoon as they lost 3-0 at home to Rochdale, missing a penalty and finishing with 10 men.
Joel Grant's 19th-minute goal gave Wycombe Wanderers a 1-0 win away to Oxford United.
