Omarchy 4 aka 'Quattro' is the biggest release since the project started. The entire desktop shell has been reimagined in Quickshell - the bar, launcher, menus, notifications, on-screen displays, control panels, lock screen, and polkit agent now all live inside a single long-running shell process with a plugin architecture. That means Waybar, Walker, Mako, SwayOSD, hyprlock, hypridle, swaybg and polkit-gnome are all gone, replaced by one coherent, fully-themed, IPC-scriptable shell. Headline features: reimagine the entire desktop shell in Quickshell; move Omarchy internals from git to system packages for safely separating user modifications; offer dual-boot installation when free space is available; setup a machine for a new owner during install, so OEMs and gift givers can prepare a machine for others; allow for factory reset from new Quattro installs for safe resale/gifting of your machine; shrink the ISO image by over a gigabyte (now under 6GB); speed up installation by +30%; convert all Hyprland configurations to lua for full 0.56 compatibility....
