What is k0s?

k0s keeps four Kubernetes branches patched in lockstep, one backport at a time.

The release feed is four maintenance branches — 1.33 through 1.36 — moving in near-formation, plus a 1.37 alpha collecting the unbackported work. Almost every entry is a list of bot-authored bumps: Kubernetes patch versions, etcd, containerd, Calico, Traefik, CoreDNS, kube-router, Alpine and Go. The few human-authored items are small operational fixes, such as keeping the konnectivity server count above zero, distinguishing pending from performed restarts in Autopilot, and omitting an anonymous-auth default when the authentication config already sets it.

What is Trunk?

Trunk is methodically maturing Merge Queue and Flaky Tests into enterprise-grade CI infrastructure.

Trunk's recent work is almost entirely incremental hardening of its two core products: Merge Queue and Flaky Tests. The cadence shows a clear enterprise-readiness pattern — a Terraform provider, public API endpoints, Prometheus-compatible metrics, multiple queues per repo, and deeper Slack and Jira integration. Nothing here redefines the product; it's the steady filling-in of operational and integration gaps larger teams require.

k0s keeps four Kubernetes branches patched in lockstep, one backport at a time.

◆ Current state

The release feed is four maintenance branches — 1.33 through 1.36 — moving in near-formation, plus a 1.37 alpha collecting the unbackported work. Almost every entry is a list of bot-authored bumps: Kubernetes patch versions, etcd, containerd, Calico, Traefik, CoreDNS, kube-router, Alpine and Go. The few human-authored items are small operational fixes, such as keeping the konnectivity server count above zero, distinguishing pending from performed restarts in Autopilot, and omitting an anonymous-auth default when the authentication config already sets it.

◆ Where it's heading

This is a distribution whose product is currency and consistency: the same fix reaches every supported branch within days, and the component matrix stays close to upstream. Autopilot is the one area receiving actual behavior work rather than version bumps, which is where a self-managing cluster story would have to come from. The 1.37 alpha line is where riscv64 support and larger refactors are accumulating.

◆ Prediction

Expect the 1.37 line to move from alpha toward a release candidate with the riscv64 and etcd 3.7 work carried forward, while 1.33 through 1.36 continue their weekly bump cadence.

Trunk is methodically maturing Merge Queue and Flaky Tests into enterprise-grade CI infrastructure.

◆ Current state

Trunk's recent work is almost entirely incremental hardening of its two core products: Merge Queue and Flaky Tests. The cadence shows a clear enterprise-readiness pattern — a Terraform provider, public API endpoints, Prometheus-compatible metrics, multiple queues per repo, and deeper Slack and Jira integration. Nothing here redefines the product; it's the steady filling-in of operational and integration gaps larger teams require.

◆ Where it's heading

Trunk is making Merge Queue programmable and observable: APIs, IaC, metrics endpoints, and richer dashboards point at customers who manage CI at scale and want it wired into their existing tooling. Flaky Tests is gaining automation hooks (Jira issue creation, configurable threshold monitors) that move it from detection toward workflow.

◆ Prediction

Expect continued API, metrics, and integration depth on Merge Queue, and more automated remediation paths for Flaky Tests, as Trunk leans into programmability for larger engineering orgs.
