Though Steam News and the Dota 2 website are silent on the topic, the DOTA 2 Twitter feed announces the Dota 2 Reborn update is now live, offering a Source Engine 2 makeover for Valve's MOBA. Word is: "We are rolling out the Reborn update over the next couple of hours. Matchmaking is now only available in Reborn." This page is where to look for details on what's changed with the new version. Thanks PC Gamer.
