How are the map files kept current in TripleA after downloading?

If a new version of a map file is released are these update automatically if you already downloaded them?

Once a map has been updated on the server, you usually will notice it by the "Updates Available" register to be found when you hit "Download Maps". You can then start the update from there.
This applies to current pre-release versions of TripleA.

I haven't used the old stable for a while, but here IIRC the updated maps are represented by the map name showing in italics. Hit that name and a button to start the update will appear.

Note that savegames always run with the map-status at the time the game has been started. In other words: Updates of maps do not affect existent games.
