In this week's patch updates, Valve continued their routine of bug fixes and user interface improvements following up to The International. The highlight of the update, however, would be the addition of over fifty new items made by the community into the in game store.
Released at the start of June, the Dota 2 Steam Workshop was created and allowed fans to upload their content while others voted and commented on the ones they liked.
This week, Valve has sieved through and ported the cream of the crop into the main client, while the original fan creators earned a share of the sales profit from the in game store.
Be sure to check out the full list of changes.
