Sharps was signed by manager Steve Evans last summer but ended up spending the second half of last term on loan at Burton.
And Evans has deemed the 32-year-old surplus to requirements ahead of the new season, providing him with the opportunity to find a new club.
"I would like to thank Ian for the effort and commitment he has given this club, and him and his young family will always be welcome as my guest at the New York Stadium," said Evans.
