Week of November 2, 2026

What shipped

Why it matters

This week brings releases across four Kubernetes lines plus a stable channel update to v1.37.2+k3s1, so users on 1.34, 1.35, 1.36 and 1.37 have new builds. The Traefik chart upgrade carries a breaking rename of the ingress-nginx migration provider name, which matters for anyone migrating from ingress-nginx. The install script fix makes the k3s-selinux version lookup work under dash instead of running only once.

Releases out this week: v1.34.13, v1.35.10, v1.36.6 and v1.37.2+k3s1, plus the stable channel updated to v1.37.2+k3s1. Traefik chart v40 renames the ingress-nginx migration provider to kubernetesIngressNGINX, so check your config. install.sh no longer relies on bash brace expansi

This week brings releases across four Kubernetes lines: v1.34.13+k3s1, v1.35.10+k3s1, v1.36.6+k3s1 and v1.37.2+k3s1. The 1.36 and 1.37 releases update Kubernetes to their respective patch versions, bump containerd to v2.3.6, and include help and gateway-api updates. The stable channel now points to v1.37.2+k3s1. If you use Traefik, note that the chart upgrade to v40.x renames the ingress-nginx migration provider from kubernetesIngressNginx to kubernetesIngressNGINX, which is a breaking change. Separately, install.sh no longer uses brace expansion, so the k3s-selinux version lookup runs correctly under dash, and command detection uses command -v.

Week of October 26, 2026

What shipped

Why it matters

This week brings a bugfix for containerd metrics configuration, a fix that stops airgap tarball re-imports on every start, and container image pinning, all of which affect day-to-day cluster behavior. It also adds flannel vxlan VNI and port configuration over environment variables for Linux servers so agents follow the server. Alongside these, release candidates for several versions bump x/net and backport bundled binary build changes, and CI runners and contributor docs were cleaned up.

This week: containerd metrics plugin restored, airgap tarballs no longer re-imported on every start, pause image pinning fixed, and flannel vxlan VNI and port configurable via env vars. Release candidates for 1.34 through 1.37 also bump x/net.

Post for LinkedIn

This week in the repository: the containerd server and metrics plugin was restored so metrics can be configured again, airgap image tarballs are no longer re-imported on every start, the pause image is normalized so pinning works, and tcpproxy closes backend connections when clients disconnect. The supervisor http server now sets an IdleTimeout, and flannel vxlan VNI and port can be configured via environment variables on Linux servers with agents following. Temporary etcd datastore copies are cleaned up on error paths, dead contributor doc links were fixed, CI runners are pinned to ubuntu-24.04, and release candidates for 1.34 through 1.37 bump x/net and pass bundled binary build changes through.

Week of October 12, 2026

What shipped

Why it matters

This week brings several correctness fixes that matter to operators: the proxy goroutine leak, etcd member cleanup when etcd is disabled on an existing server, and error reporting during image pre-pull. Dependency updates to kube-router and containerd across release branches keep the bundled components current, and new automation for Traefik image bumps and a gateway-api test add coverage for the shipping defaults.

This week: fixed a proxy goroutine leak, fixed etcd member removal when etcd is disabled on an existing server, and image pre-pull now reports list read errors. Also kube-router v2.11.1, containerd bumps across release branches, Updatecli automation for Traefik, and a new gateway

Post for LinkedIn

This week in K3s: we fixed a goroutine leak in the proxy when both directions fail at about the same time, fixed etcd member removal when etcd is disabled on a server that previously ran embedded etcd, and made image pre-pulling report read errors from the pre-pull image list. On the dependency side, kube-router moved to v2.11.1 and containerd was bumped to v2.3.7 on release-1.36 and release-1.37 and to v2.2.10 on release-1.34 and release-1.35. We also added Updatecli automation to bump the bundled Traefik image, added a docker test for the gateway-api receiver, and removed unused replace directives.

Week of October 5, 2026

What shipped

Why it matters

This week brought a tagged v1.36.5+k3s1 release that upgrades the Traefik chart to v40.x, a breaking change for the ingress-nginx migration because the provider name becomes kubernetesIngressNGINX. Users dealing with private registries and SELinux enforcing environments got fixes for vagrant-k3s registry errors and for local-path PVs stuck in Released. Dependency bumps to containerd and gateway-api, plus a new etcd snapshot restriction option, landed across the maintained release branches.

This week k3s published v1.36.5+k3s1. The release upgrades the Traefik chart to v40.x, which includes a breaking change for the ingress-nginx migration: the provider name changes from kubernetesIngressNginx to kubernetesIngressNGINX. We also bumped containerd to v2.3.6 on current branches and v2.2.9 on older ones to fix some CVEs, moved gateway-api to 1.6.3, fixed local-path PV deletion under SELinux enforcing, fixed private registry usage with vagrant-k3s 0.6.0, and added an etcd snapshot restrictions option.
