He did spend time on loan at Newport County and Shrewsbury, while he played for the club's U21 team.
However, he was not thought to be a player that manager Eddie Howe could use as a first teamer.
Bondswell released a statement on X: "My time at Newcastle has come to an end.
I'll be leaving with many great memories and I want to thank everyone who has been a part of that so thank you to the fans for your support, it's been an honor to be able to wear the black and white shirt in front of you."
