- Platform/SRE — Learn: RangeStream is still beta in v1.37 (requires etcd v3.7), so not yet production-adoptable, but SREs running clusters with many large objects (e.g., Pods at scale) should track this as a near-term mitigation for API server and etcd OOM risk during cache repopulation.
- CI/CD — Skip
- Leader — Skip
- Signals: Kubernetes 1.37 EOL 2027-10-28 · etcd 3.7 supported
