Game Updates
Occasionally The Sims 3 will offer game updates to introduce new content or to fix known issues.
You will be notified when an update is available if you have Automatic Updates checked. Game updates are also available on the Game Updates panel if you decide not to update at that time or do not have Automatic Updates checked. Click the Refresh button to see if any new updates have been made available.
The current installed game version is displayed on the main launcher panel.
