Team Fortress 2 adds microtransactions, trading [Update]

Besides the microtransactions, this newest update adds the long-awaited trading feature, the ability to gift items, the Polycount pack, minigames (although we don't know what kind), and in-game customizable items. The item system is currently down in-game, presumably because it is being hammered by players. There's also a humorous comic which offers an in-universe explanation for the system.
Update: In addition to the new in-game trading and buying system, Team Fortress 2 is currently on sale via Steam for just $9.99, a 50 percent price cut from its normal price
Full patch notes after the cut.
