According to the release notes, the new Radeon Software Adrenalin 20.1.2 driver adds support for BANDAI NAMCO Entertainment's Dragon Ball Z: Kakarot game, which launches tomorrow, January 17th, as well as adds support for Vulkan 1.2, making it conformant with the Vulkan 1.2 specification.
AMD also fixed some issues, including ones seen with UE4 based titles like KovaaK 2.0: The Meta, Tetris Effect and Snooker 19, all of which failed to launch with Adrenalin 2020 Edition software. It also fixes issues seen with some single display Radeon RX 5700 series graphics cards where configurations were experiencing intermittent reboots when the system is left idle on desktop.
The new Radeon Software Adrenalin 2020 Edition 20.1.2 is available for 64-bit versions of Windows 10 and Windows 7.
