GhostBSD 26.1-R15.0p2 introduces a major update by transitioning to FreeBSD 15.0-RELEASE, incorporating upstream improvements like expanded hardware support and security enhancements. Key changes include switching the default shell to zsh, adopting XLibre as the default display server, and adding Enterprise WPA (802.1X/EAP) and WireGuard support in NetworkMGR. Update Station now handles boot environment-based major version upgrades, while Software Station features faster package searches via bisect-based algorithms. The release also refreshes the visual identity with new wallpapers, icon themes, and theme variants, though existing users upgrading will retain their current display server (Xorg or otherwise). Notable fixes address UEFI boot issues, missing installers in XFCE, and VirtualBox EFI mode compatibility, with a known post-upgrade issue involving invisible panels (resolved by logging out and back in).
