Most of today's movement is documentation and test plumbing rather than runtime behavior, with one new cloud-provider-aws annotation and a govulncheck-driven dependency bump the only things that touch code paths you run.

KEP-5495: blog post about IPVS deprecation kubernetes/website

by danwinship

danwinship's new blog post covers the IPVS deprecation tracked as KEP-5495 and walks through migrating service load balancing to iptables or nftables. This is the reference to read before your clusters' kube-proxy mode becomes a migration project rather than a config field.

kubernetes-mixin: add required checks kubernetes/test-infra

by skl

Branch protection for kubernetes-mixin now enforces required checks, mirrored from the checks listed in the repo's own CI workflow. Contributors get rejected at the branch rather than in review.

feat: Add ALPN policy annotation for NLB TLS listeners kubernetes/cloud-provider-aws

by alimx07

cloud-provider-aws adds the service.beta.kubernetes.io/aws-load-balancer-alpn-policy annotation for NLB TLS listeners, accepting HTTP1Only, HTTP2Only, HTTP2Optional, HTTP2Preferred, and None. It applies only when aws-load-balancer-ssl-cert is also set, and removing the annotation resets an existing listener to None.

Bump golang.org/x/net to v0.60.0 kubernetes/cloud-provider-aws

by Davanum Srinivas

Dims bumped golang.org/x/net to v0.60.0, closing GO-2026-6603, GO-2026-6610, GO-2026-6611, GO-2026-6612 and GO-2026-6617 as reported by govulncheck. The same PR replaces every staging module in hack/switch-to-latest-k8s.sh by looping over staging/src/k8s.io/*, since the fixed replace list was missing k8s.io/ktesting and go mod tidy failed against Kubernetes master, red since 2026-10-10.

by RhennanCordeiro
