Rangers have confirmed the signing of Dundee United striker Jon Daly.
St Mirren defenders Sean Kelly and Jason Naismith have signed new one-year contracts with the club.
Tyrone Barnett would be "delighted" if he never returned to Peterborough.
The striker moved from London Road to Ipswich on loan last week after he was placed on the transfer list following a police caution for an incident on a night out in Peterborough city centre.
"Obviously I'm contracted there so that is my parent club," Barnett told BBC Radio Suffolk. "But if I could get away I would be delighted.
"There's always regrets because I didn't want to leave the club in the way that I did. I'd rather it be on good terms. But that's life. You take it, get on with it and hopefully I can move on.
"I'd say [to Ipswich fans] take it with a pinch of salt. The lads and people who know me know I'm not a troublemaker or whatever people want to come up with.
"When you get to know me I'm an all right guy."
