Whisky 3.9.0 brings a Liquid Glass app icon with a dark appearance on macOS 26, a per-program Metal HUD, .cmd script support, a Locale Override that works for launcher bottles, and a security update to the app's updater.
Added
- A Liquid Glass app icon with a dark appearance on macOS 26, in the Dock, the app switcher and Whisky's own dialogs. macOS 15 keeps the existing icon (#310).
- The Metal HUD can be set per program. The bottle's HUD draws over every Metal renderer in the bottle, Steam's store and overlay included, so a program can now turn it on for itself alone, or turn the bottle's HUD off for itself (#313).
- Whisky offers once to import bottles from the original Whisky when it finds any that aren't registered yet. File > Migrate from the Original Whisky still does it any time (#323, fixes #321).
Fixed
.cmdscripts run like.batfiles, from the Run panel, the bottle's Run button, and by opening them from Finder. Upper-case extensions such asSETUP.BATwork too; they used to launch as programs and fail (#331).- Locale Override works for Steam, EA App, Epic Games, Battle.net and Rockstar bottles. Those launchers' presets forced US English onto every game they start, and the picker had no effect, so a game that takes its region or language from the Windows locale (TEKKEN 8's online region, for one) can now get the one you choose. Auto still uses US English for those launchers (#332, part of #330).
Security
- The Sparkle updater is updated to 2.10.1, fixing two Sparkle advisories: while an update installed, another local process could send the installer forged update details (GHSA-g3hp-f6mg-559v), and a crafted delta update could write outside the app (GHSA-hg88-v3cw-3qrh; Whisky ships full updates only, so this one wasn't reachable) (#336). Installed copies update to 3.9.0 through their current updater; later updates use the new one.
