The Wine 11.20 development release is out now bringing another set of improvements for running Windows apps / games on SteamOS / Linux.

Quick little reminder for you - Wine is one of the main bits of software that powers Valve's amazing Proton (along with DXVK and VKD3D-Proton)! This enables tens of thousands of games to run on SteamOS / Steam Deck / Steam Machine and Steam Frame.

Key Features of Wine 11.20

• Relay debugging for ARM64EC.
• Improvements in XML validation.
• CDROM support moved to the Mount Manager.
• Various bug fixes.
