There was an update for the only well-developed Free football management simulation I know of, Bygfoot 2 was released. Sadly the lead developer is moving on so it may be the last release if nobody takes over maintainership. Saying that, open source project addiction may bring him back.
Bygfoot is fun but the user interface can be fairly non-intuitive and the game lacks depth when it comes to player management and information - e.g. there's no indication of a player's performance in the game. Outside of the players, there are plenty of features. With some UI love and elaboration on the player management it could be a very competent footy manager.
There was also an update to Alien Arena 2006; another mod-turned-standalone freeware deathmatch game. Since Q3A now is available under a Free license, I wish these mods would adopt a similar approach. Still, that is their perrogative.
Today I received a laptop with Windows installed, so if you know any Windows-only Free Software games then please let me know. I'm going to have to make the games list a little more refined (add a platform indicator of some sort) but I'd like to promote all Free games, regardless of their platform.
