GitHub has tightened minimum-version enforcement for self-hosted runners: brownouts began September 14, and from September 25, 2026 any runner not updated within 30 days stops receiving jobs. The failure is silent — jobs sit in “Queued” with no error: audit your runners before the next window.
Moved into maintenance mode on August 27, 2026, Kubernetes 1.34 reaches end of life on October 27, at which point AWS, Azure and Google all bill $0.60 per cluster per hour — $438 a month — to keep patching it. Upgrade before the deadline: the surcharge buys no features, only the survival of an outdated control plane.
The Proxmox VE 8 branch, released in June 2023 on Debian 12, reaches end of life in August 2026: hypervisor patches stop even though Debian LTS continues. For anyone running Ceph or old containers, the VE 9 upgrade is two separate projects — and a rollback that goes through restore, not reverse migration.
