With The International regional qualifiers rapidly approaching, Valve is hoping to help add a little bit of polish to Dota 2. That's why the game is set to undergo a large (and I mean large) amount of small changes with the upcoming Spring Cleaning update.
The Spring Cleaning update, which will arrive in conjunction with Gameplay Update 6.81, adds dozens upon dozens of changes across the game's inventory system, interface, and workshop. It also adds a gargantuan list of bug fixes and balance tweaks across all of the game's Heroes.
The update also adds a pair of new chests: Treasure of Sinister Arcanery and Treasure of the Cosmic Abyss. No seal or treasure drop will be required for either of these items, as they can be purchased directly from the Dota 2 Store or picked up from the Steam Community Market. Each pickup will grant a full set when unlocked and also has a chance for a bonus drop.
The Spring Cleaning update is expected to hit next week. The full list of changes can be found on Dota 2's website.
