Kubernetes 1.35 'World Tree' focuses on platform stability and security improvements rather than flashy features. Key updates include stable OCI image volumes for mounting data without init containers, migration from deprecated SPDY to WebSockets for streaming commands, explicit traffic distribution policies (PreferSameNode/PreferSameZone), removal of cgroup v1 support, Pod certificates for workload identity, node-declared features for safer scheduling during upgrades, and constrained impersonation to limit privilege escalation. These changes strengthen Kubernetes' foundations, improve security boundaries, and eliminate legacy technical debt.
