According to the release notes, the new Radeon Software Crimson Edition brings support and optimizations for the new DirectX 12 mode in Deus Ex: Mankind Divided as well as a new AMD Crossfire profile for DOTA 2 in DirectX 11.

There are a couple of fixed problems, including flickering  seen with 144Hz non-FreeSync displays, some bugs  in games and applications like DirT Rally, Grand Theft Auto V, Doom, Total War: Warhammer, SteamVR benchmark and others. It also fixes problems with Radeon Settings and Radeon Software on some AMD Crossfire configurations as well as an issue where RX 400 series graphics cards experience high GPU usage when resuming from sleep.
