Wine 11.20, released on October 16, 2026, introduces notable features including ARM64EC relay debugging, which allows developers to trace calls between ARM and x64 code on Windows 11 on ARM. The release also improves XML validation to enhance compatibility with installers like Office 2013 Click-to-Run and reorganizes CD-ROM support into the Mount Manager for better functionality. Additionally, a critical memory-safety fix addresses a stack buffer overflow in the command interpreter, enhancing security. As part of the ongoing 11.x development cycle, this release is a step towards the upcoming Wine 12.0, expected in early 2027

Wine 11.20 Release: ARM64EC Relay Debugging and Stack Overflow Fix

Wine 11.20, the latest bi-weekly development release, shipped on 16 October 2026 with 24 bugs fixed. The headline feature is relay debugging for ARM64EC, letting developers trace calls across the ARM/x64 boundary on Windows 11 on ARM. It also tightens XML validation to unbreak installers like Office 2013 Click-to-Run, moves CD-ROM logic into the Mount Manager, and closes a stack buffer overflow in cmd. Lead contributor Alexandre Julliard tops the commit list as the project heads toward Wine 12.0 in early 2027.
