The next time you start up The Sims 3, that annoying little EA Downloader in your task bar will automatically update the game to version 1.3. It's a massive patch in terms of the number of changes. I've singled out a few that are particularly noteworthy.

• Fixes to Story Progression. Babies will no longer be born to single parents.
• Camera memory hotkeys now properly remember floor level.
• The "Call Over" Interaction is now available on seated Sims.
• Non-player Sim autonomy now runs more quickly for Sims on screen and nearby (neighbors won't spend time standing in their front yards or not moving on community lots)
• Relationships are properly preserved when merging a newly created household into an existing household.

And here are a few that I'd never even noticed. I have mixed feelings about some of them being gone before I could try them.

• "Become Enemies with Child" wish no longer appears.
• Prevented a case where toddlers were allowed to escape a lot and wander freely.
• Sims will no longer get a wish to ask their husband to be their boyfriend.
• "Woohoo" interaction now counts as a romantic interaction.
• Eating specific prepared meals no longer has an impact on an unborn baby's gender.
• A faint line is no longer visible on the heads of babies.
• Sims can no longer "Try for Baby" with the Grim Reaper.
