Defender Adam Virgo and goalkeeper Scott Bevan have not been given new contracts but will remain with the club as they recover from injury.
Virgo, 30, missed the majority of the season with a knee problem while Bevan, 33, has not played since the 2011-12 season because of an ongoing wrist problem.
"Neither of them have played a game since I've been here so we're not in a position to renew them," manager John Ward told BBC Radio Bristol. "But we have a duty of care to make sure the guys are given the best opportunity to move on.
