Released: 19 September 2019
As usual the update is save game compatible, so you don't have to start a new save game. However, any fixes related to competitions rules or schedules require you to start a new game.
To update you will need to close down Football Manager 2019 and re-launch for it to update. If this does not work for you or you feel it has not updated you will need to restart Steam.
Even if that doesn't do the trick, then verify the game cache will.
