The Battle Report Update is out now for Dota 2, with the majority of it being for Dota Plus but there's also some of the usual balancing changes and a nice improvement for people using the Vulkan renderer.
Valve say it has a "significant performance improvement aimed at removing hitching when playing with the Vulkan renderer". They're making use of the VK_EXT_graphics_pipeline_library extension, which is currently only supported by the NVIDIA Vulkan Beta driver but it will be coming to the stable drivers for all vendors eventually. So if you're on NVIDIA, perhaps give it a try and see what you think.
For Dota Plus there's loads new! Including a new Battle Report screen to give you in-depth info on your performance plus Weekend Spotlight, a new queue for everyone to explore an assortment of Dota game modes and events all while stocking up on Dota Plus Shards. Valve also adjusted Immortal Item spell effects, so they can now be equipped regardless of the item you have equipped.
