Omarchy 4.0.5 updates to Qt 6.12, Linux 7.2.8 with BORE scheduler

Omarchy 4.0.5 ships as a refinement release ahead of a planned feature update. The distribution moves its desktop shell to Qt 6.12, updates the underlying Arch package set to the October snapshot, and switches the default kernel to Linux 7.2.8 using the BORE scheduler. The release also addresses hardware-specific bugs for Dell XPS 13, KEF USB speakers, NVIDIA hybrid laptops, and Apple T2 Macs, alongside security fixes for PATH injection and factory reset procedures.

What's in Omarchy 4.0.5

• Kernel: Default moves to Linux 7.2.8 with BORE (Burst-Oriented Response Enhancer) scheduler replacing previous default
• Qt migration: Full shell transition to Qt 6.12 required fixes for colors, panels, and third-party plugin compatibility
• Package priority: Omarchy's own repository now takes precedence over upstream Arch repositories
• Security fixes: Removed automatic PATH injection in project directories; root password hashes now erased during factory reset; helper scripts hardened against malicious CLI flags
• Hardware fixes: Dell XPS 13 Panther Lake speakers, KEF LSX II LT USB speaker lockups, NVIDIA hybrid laptop env vars, T2 Mac Broadcom firmware fetcher
• Desktop fixes: SSH firewall rule persistence, lid-closure shutdown interruption, idle timeout 0 behavior, monitor on/off toggle

Why it matters

The BORE scheduler adoption and Qt 6.12 migration place Omarchy among the more actively maintained Arch derivatives tracking recent desktop stack changes. The security fixes for PATH injection and factory reset handling address practical deployment concerns for a distribution positioning itself as a polished desktop alternative.
