Unified launcher for Windows games on Linux (UMU) v1.1.3 out now

Continuing to improve compatibility with Windows games on Linux outside of Steam, the Unified launcher for Windows games on Linux (UMU) has another release out now.

Following on from the first official release in early October, this release focuses on various bug fixes and ensuring it works well for Lutris and the Heroic Games Launcher.

A refresher on what it is: forming part of Open Wine Components, it's not a launcher in the sense of it being an app like Steam, Heroic Games, Lutris, Bottles, Legendary and so on. Instead, it's a tool that various apps can use to run Windows games on Linux, acting as a copy of the Steam Runtime Tools and Steam Linux Runtime that Valve uses for Proton to allow Proton to properly run outside of Steam. In case you missed it, the Zoom Platform store have begun using it too.

From the v1.1.3 changelog:

• Fixed issue that prevented heroic and lutris from using UMU as a game installer instead of wine
• Fixed issue where sometimes DISPLAY envvar would get lost between handoff from umu to pressure vessel
• Refactor/cleanup of window management code under gamescope -- both lutris and heroic can fully install and run games inside gamescope while both inside or outside of flatpak now.
• Winetricks is now fully useable through UMU and GE-Proton/UMU-Proton
• Updated apparmor bwrap permission profile to recommendations from upstream apparmor folks
• Added a basic shim script to allow performing modifications inside the pressure vessel container after UMU handoff has happened.
• Cleaned up standalone flatpak script to prepare for submission upstream
• Fixed a few places that needed lock files in place to prevent prefix corruption if multiple instances are running
• Missing 32 bit dependencies added for Nix packaging

Notes:

• We're still working out github task attachments for releases being automated. For now we're manually attaching from the latest 1.1.3 builds in the actions section. Thanks for baring with us.

• A refactor was submitted to Lutris to allow full UMU functionality on the lutris side:
  lutris/lutris@3a45272

• Lutris and Heroic also should be receiving the permissions they need in flatpak soon if not already:
  flathub-infra/flatpak-builder-lint@7aa2300
