3.0.3-RC

Added

• Proxmox VE arm64 installer support
• NixOS 26.05 and nixos-unstable rolling release
• Mageia 10

Changed

• Proxmox menu entries and boot targets are now gated by architecture, so each platform only sees the products available for it
• VGA framebuffer kernel parameters are now only applied to amd64 Proxmox boots
• Updated Alpine Linux to 3.24
• Updated Arch Linux to 2026.08.01
• Updated Fedora CoreOS to 44.20260707.3.1 (stable), 44.20260720.2.1 (testing), and 44.20260720.1.1 (next)
• Updated IPFire to 2.29 Core203
• Updated SmartOS to 20260723T000757Z
• Updated actions/checkout to v7
• Updated actions/setup-python to v7
• Various distribution version updates across all supported operating systems

Fixed

• Duplicate Proxmox VE menu entries and an incorrect kernel URL that appeared once a second Proxmox VE endpoint was defined for another architecture
• Custom menu options (GitHub, URL, and local custom.ipxe) now clear the menu before showing the error screen when the chain fails, breaking a fallback loop
• Empty Mageia menu entry caused by the version checker tracking a release directory that no longer exists on the mirror
