Valve just released a massive patch for DotA 2 fixing or streamlining hundreds of small bugs/UI fixes or cosmetic details that the community asked for this summer. This in the same week that they've completely revamped their ranked system to help Party Queue integrate with solo queue.
Also just a week before their $31M+ tournament, The International 9.
Kind of makes me glad that it was Valve that scooped up the rights for DotA, not some other lesser company. A game that has lasted for over 15 years deserves nothing less.
