Goalkeeper Costel Pantilimon has parted company with the club.
The 33-year-old stopper has signed for Turkish side Denizlispor.
He has spent two years at the City Ground, but has not been part of the first-team set-up under Sabri Lamouchi.
And his time at the City Ground looks set to come to an end, with a two-year contract with the Turkish side said to have been agreed.

The Turkish club announced the deal on social media:
He will join a team which finished 14th in Turkey’s top-flight last season and who are managed by former Real Madrid and Barcelona midfielder Robert Prosinecki.
The Romanian stopper initially joined Forest on loan in January 2018, before making the switch permanently that summer.
He was the club’s No.1 in the 2018/19 campaign and has made a total of 57 appearances in the Garibaldi.
However, he fell out of favour when Lamouchi took charge little more than 12 months ago, and spent the second half of last term on loan at Omonia Nicosia, in Cyprus.
