Maru-gun 0.8.1 Install the application in a writable directory of your choice. On first launch, choose the existing Windower4/addons folder and download the application/addon release. Startup checks for updates; updates activate both components together after all game clients and Maru-gun windows have closed. Includes party settings, healing/buff/weapon-skill controls, Anitanaru launcher artwork, managed addon bootstrap, and signed update verification. The initial public platform is Linux x86_64 with Windower running under Wine. Windows installer publication awaits a native Windows build and installation qualification. A Windows download is not included in this release. Linux requires glibc 2.36 or newer and Qt display libraries. Close all FFXI and Windower clients when installing or activating an update. Existing unrelated addon directories are preserved; move an existing marugun addon to a backup folder before selecting that Windower installation. Qualification: automated checks and isolated native Linux installation/update tests passed. Live multibox gameplay qualification remains outstanding. This release bundles trusted HTTPS certificates for the frozen runtime. The 0.8.0 installer was withdrawn during the public download check. If you downloaded 0.8.0, use this new installer in an empty application directory.
