Midfielder Miguel Pallardo has signed a new one-year deal with newly-promoted Hearts.
Liam Rosenior has thanked the fans of Hull City for "five wonderful years".
Former England goalkeeper David James has been told he can leave npower Championship club Bristol City.
The Robins announced their retained list on Tuesday and revealed the 41-year-old, capped 53 times by his country, would not be offered a new deal.
James, who counts Liverpool, Aston Villa and Manchester City among his former clubs, was signed by Steve Coppell in August 2010 during the former City manager's four-month spell in charge.
The former Watford trainee had only recently returned from the World Cup in South Africa, where he featured in three of England's four matches, keeping two clean sheets.
Robins manager Derek McInnes has decided to consider alternative options and James was among eight players informed their futures lie away from Ashton Gate.
During his two seasons with the club, James made 81 league appearances and played a substantial part in their successful battle against the drop in this campaign.
As a sign of McInnes' desire to look to the future, youth team keeper Lewis Carey has been offered a professional deal.
