Meek Mill Free At Last Released from Prison

5:55 PM PT -- Meek just posted his first pic after prison -- chilling in a living room and cracking jokes about a friend's broken foot. Good to be home.
Christmas has come early for Meek Mill ... he's getting out of prison today.

Mill has been in a Philadelphia correctional facility since July ... when a judge sentenced him to 3-6 months behind bars for violating probation.

Mill was granted parole on the condition he complete a community service and treatment program. It's unclear exactly what that program will involve, at this point.

One hang up ... Mill is not allowed to travel outside of Philly until he completes the programs. So, touring is off the table for now.
