The week's patch update welcomes the highly anticipated arrival of Shadow Demon into Dota 2 Test. Known for its popularity in the Chinese competitive scene and for its Disruption ability being a direct counter to Anti Mage, its introduction to Dota 2 may be the last nail in the coffin for the popular carry hero.
Alongside Shadow Demon, a couple of tweaks to the User Interface ("Adding copy + paste support") as well as gameplay fixes (" Updated Dota 2 to 6.74 parity. Tournament mode will be updated to this next week.") were made with the current test version soon to be ported into Normal Dota 2 tomorrow and 6.74 changes next week.
This may just spell yet another major shift in the current metagame, seeing as improvements were made to heroes like Shadowfiend while heroes like Dark Seer and Invoker received nerfs to their vital spell combinations in 6.74.
