Peterborough United have signed goalkeeper Paul Jones on a one-year deal, while defender Gabby Zakuani has agreed a new three-year deal.
Jones, 24, arrives on a free transfer from Exeter following a four-month loan spell at London Road last term.
Centre-half Zakuani has been with Posh since September 2008 and featured 38 times in last season's promotion-winning campaign.
"I feel at home," the 25-year-old told BBC Radio Cambridgeshire.
"I love the place, and it helps when you're playing well and you've got the fans loving you.

"There are always rumours about other things but I don't listen to that."
Jones found himself understudy to Joe Lewis for much of his Peterborough loan stint, but injury to Lewis meant Jones played in all three League One play-off matches.
"The way he performed in the play-off final against Huddersfield Town was outstanding," Posh director of football Barry Fry told the club website.
"He is a major reason why we got promoted. He was thrown in the deep end and it must have been unbelievable pressure on him."
Jones started his career at Leyton Orient but failed to make a first-team appearance before joining Exeter in late 2004, initially on loan.
He appeared 201 times for the Grecians, including 22 games last season.
