Apr 1, 2026April 2026: Major platform upgrades and reliability enhancements across the eve subsystem, focused on upgrade-driven compatibility, storage reliability, cluster readiness, and secure state migration. Delivered coordinated KubeVirt upgrade to 1.7.3 with a new VMI descheduler to improve boot failover readiness and eviction control, along with necessary API compatibility fixes and env patches. Upgraded Longhorn manager to v1.9.1 and introduced configurable per-node disk reservation to improve edge-device storage reliability, plus a default backup-target handling fix. Hardened Kubernetes readiness checks and lifecycle stability: extended boot wait logic, introduced a tunable drain-detection window to avoid unnecessary evictions during cluster-wide drains, and fixed a cluster-delete regression. Migrated kube-save-var-lib to a secure vault location, preserving data integrity during the transition.

Dec 1, 2025December 2025 performance highlights for lf-edge/eve: Delivered automated, maintainable k3s configuration management, hardened upgrade/restart workflows, and build/test environment stabilization, delivering measurable reliability and deployment velocity gains. Key features include dynamic k3s configuration overrides merged with defaults via a directory-based config scheme, and an automatic restart of the k3s server after updates. Enhancement of k3s restart handling reduces downtime during component updates, with a new default timeout for Kubernetes component upgrades. Build/test improvements stabilized the local and CI environments: fixed JSON output in spec.sh to unblock pkg/debug builds, filtered non-link files in /sys/class/net, and added a Dockerfile for faster testing iteration. Introduced strict node scheduling with AffinityType to ensure designated nodes are used and prevent failover under cluster app load. These changes improve consistency across environments, reduce manual toil, and accelerate safe rollouts.

Sep 1, 20252025-09 monthly summary for lf-edge/eve focusing on reliability, resource optimization, and lifecycle resilience. Key features delivered include Tie Breaker Node Reservation for EVE clustering to reserve designated nodes for essential cluster functions (etcd quorum) and to prevent core workloads from scheduling on these nodes. This feature also controls storage behavior by selecting a storage class with fewer replicas (2) for longhorn replicas on tie-breaker nodes, reducing contention and failure risk. Addressed Kubernetes hostname compatibility by introducing convert_to_k8s_compatible to normalize node names to lowercase hyphenated forms compatible with Kubernetes hostname conventions, improving NDM verification and descheduler processing. Fixed boot-sequence issues by ensuring the /var/lib/all_components_initialized flag is recreated after conversions between single-node and cluster modes using an added touch in cluster-init.sh. These changes collectively improve cluster stability, resource utilization, and lifecycle reliability, enabling safer upgrades and node conversions.
