Vermouth has been released in version v2.0.3.

Vermouth is a game launcher and manager for Linux that lets you run and manage games through different runtimes like Proton and Wine.

The release adds more downloadable Proton variants (Umu-Proton, Proton-EM, DWProton) and advanced per-game launch options for MangoHud, GameMode, Proton GameID, LSFG, SDL and custom environment variables. It also brings a toggle for runner icons and a fix for single-click selection.

Changes since v2.0.2:

• Added various Protons for download: Umu-proton, Proton-EM and DWProton
• Advanced per-game options: mangohud, gamemode, proton game ID, LSFG, SDL and environment variables; mangohud and gamescope binaries are now reachable from Flatpak
• Prevent GAMEID override with umu
• New setting to toggle runner icons, plus a View menu toggle button when the sidebar is unpinned
• Allow selection with single click activation (hold CTRL, mirrors KDE behaviour)
