Valve has just updated Dota 2, unlocking the long anticipated and requested annual Diretide event as well as two new heroes. So you can stop harassing innocent car makers now.

Xin and Kaolin, the Earth and Fire Spirits from Dota 1 have both been added to the game, rounding out the three elemental pandas from the original game.

A coaching system has also been added to the game, which will hopefully help to ease players into the often hostile community.

Finally, the update has also made some changes to the item system of Dota 2, with a greater emphasis on customising items with a new "socket system." Using gems, players can now give their items unique colours and animations.

For the full changelog, check out the official Dota 2 site.
