Charlton Athletic Academy merchandise Hanlan scored twice in 16 appearances while on loan at Stevenage during the second part of the previous season.
Boro were reportedly keen on re-signing him on a permanent basis, with Port Vale and Northampton Town also said to be interested.
Hanlan began his career at Charlton before moving on to Gillingham in 2018 and scoring 16 goals in 84 games before spending 2020–21 with Bristol Rovers.
After that, in August 2021, Hanlan joined Wycombe, where he played 111 games and scored 16 goals.
In November 2023, the forward sustained a catastrophic ACL injury that prevented him from playing for a year.
After featuring 13 times on his Wanderers’ return last season, scoring two goals, he moved to Stevenage on loan.
Hanlan’s arrival follows hot on the heels from the addition of Matty Pearson, with Robbie Gotts and Glenn Middleton having previously joined.
