Release 2026_034 (2026-08-24)

Impact

26.05

Machines will reboot to activate a changed kernel.

NixOS 26.05 platform

  • cron: restart the daemon after unexpected termination (PL-135543)

  • network-online.target: on physical machines, fails-stop when no FRR-based routes appear (PL-135151)

  • KVM hosts: reduce keepalive check’s critical threshold (PL-135533)

    This speeds up visibility of KVM host crashes in our alerting.
