Ipswich Town boss Mick McCarthy and assistant Terry Connor have agreed new three-year deals, while midfielder Stephen Hunt has signed for a year.
McCarthy, 55, was entering the final year of his contract after finishing ninth in the Championship last season, Town's best finish since 2009.
The former Wolves boss took over at Portman Road in November 2012.
"I love it here. We've made progress. I'm looking forward to making greater strides," he told BBC Radio Suffolk.
"I enjoy working for [owner] Marcus Evans. He leaves me alone to get on with it. I get no interference from him."

McCarthy steered Town away from relegation in his first season in charge and took the club to within four points of the play-offs last season.
He is the fourth manager to have worked under Evans since the businessman became owner in 2007.
Republic of Ireland international Hunt, 32, joined Ipswich on a short-term deal in November which was extended until the end of the season.
The former Reading and Wolves player appeared 24 times in the 2013-14 season.
