Kubernetes Introduces Five GA Enhancements for Clusters
9.2
Kubernetes released version 1.35 in mid-December 2025, making five major features generally available. The release includes in-place pod resource updates, fine-grained supplemental group control, PreferSameNode traffic distribution, structured authentication configuration, and OCI image volumes, which improve runtime flexibility, security, networking locality, and operability across clusters.
Key Points
- 1Enable in-place CPU and memory updates for running pods without restarts, GA in Kubernetes 1.35.
- 2Provide fine-grained supplemental-group policies to prevent unintended permission inheritance and tighten container file access.
- 3Reduce intracluster latency with PreferSameNode, simplify auth via structured config, and mount OCI images as volumes.
Scoring Rationale
High practical impact across Kubernetes deployments for operators, but mostly incremental enhancements rather than paradigm-shifting changes.
