In context: Valve announced this week that in the near future, it will begin removing Dota 2’s support for older Windows and Mac systems as well as older graphics APIs in order to streamline development. This should affect a very small percentage of players even though Dota 2 is designed to be compatible with a wide range of PCs. Towards the end of a blog post, Valve said the changes will be coming over the course of months. Eventually it will remove support for 32-bit Windows and macOS versions below 10.14. Dota 2 will also eventually only support DirectX 11 and Vulkan, dropping support for DirectX 9 and OpenGL. Finally it will stop supporting XAudio, switching to SDL Audio.
