The Braves have already made one notable trade this offseason (Tommy Hanson for Jordan Walden), and Dave O'Brien of The Atlanta Journal-Constitution says they are still involved in multiple trade talks (Twitter links). Emilio Bonifacio and Dexter Fowler are believed to be among their targets.
O'Brien notes the Braves did make a strong push for Shin-Soo Choo before he was traded to the Reds, but the team wasn't going to overpay for a player one year away from free agency. Atlanta has been seeking outfield help this offseason, though Martin Prado's versatility also allows them to seek a third baseman if they choose.
