Three new automatic updates are available when you start Steam. There's a new Steam client update that adds D3D9Ex support for the in-game overlay for ArmA II and addresses some bugs. There's also a new Source SDK Update that fixes three bugs with the Hammer editor. Finally a new Empire: Total War Update fixes two bugs in The Creative Assembly's RTS sequel, one that could crash Land Battles when grouping/ungrouping, and one that could make for invisible deployable defenses in the Grand Campaign.
