That is the core rule behind every date on the page, and it is why 1.36, 1.35, and 1.34 are the versions to watch right now.\u003C\u002Fp>\n\u003Cfigure class=\"my-6\">\u003Cimg src=\"https:\u002F\u002Fxxdpdyhzhpamafnrdkyq.supabase.co\u002Fstorage\u002Fv1\u002Fobject\u002Fpublic\u002Fcovers\u002Finline-1781768876583-i15i.png\" alt=\"Kubernetes release support windows explained clearly\" class=\"rounded-xl w-full\" loading=\"lazy\" \u002F>\u003C\u002Ffigure>\n\n\u003Cp>This model keeps upgrades moving on a predictable schedule.

The 15-week release cycle\u003C\u002Fh2>\n\u003Cp>New Kubernetes minor releases arrive every 15 weeks, so support windows slide forward quickly. That pace is what creates the constant churn between active, maintenance, and ended status on endoflife.date.\u003C\u002Fp>\n\u003Cp>For operators, the practical effect is simple: a minor release is never “new” for long. If you miss a couple of release cycles, you can fall behind support faster than you expect.\u003C\u002Fp>\n\u003Cul>\n  \u003Cli>Minor releases ship on a 15-week cadence\u003C\u002Fli>\n  \u003Cli>Patch releases are cut regularly from supported branches\u003C\u002Fli>\n  \u003Cli>Urgent patch releases can happen when severity requires it\u003C\u002Fli>\n\u003C\u002Ful>\n\u003Ch2>3. The 14-month support window\u003C\u002Fh2>\n\u003Cp>Each Kubernetes minor release is supported for about 14 months total, split into 12 months of support plus a 2-month upgrade period.

For example, 1.34 is still active now, 1.33 has already ended active support, and 1.32 is fully out of support.

Patch backports and urgent fixes\u003C\u002Fh2>\n\u003Cp>Not every fix waits for the next minor release. Kubernetes can backport security and bug fixes to the three supported branches, depending on severity and feasibility, which helps keep stable clusters patched without forcing a major jump.\u003C\u002Fp>\n\u003Cp>That backport policy is managed by the Release Managers group. In practice, this means you should watch patch versions closely, because the latest patch line is often the safest place to be inside a supported minor.\u003C\u002Fp>\n\u003Cul>\n  \u003Cli>Backports are limited to the supported branches\u003C\u002Fli>\n  \u003Cli>Severity and feasibility decide what gets ported\u003C\u002Fli>\n  \u003Cli>Patch releases can be routine or urgent\u003C\u002Fli>\n\u003C\u002Ful>\n\u003Ch2>5. Version skew matters for upgrades\u003C\u002Fh2>\n\u003Cp>Kubernetes is client-server software, so supported version skew affects both kubectl usage and upgrade order. That is why you cannot treat the control plane, nodes, and client tools as independent moving parts.\u003C\u002Fp>\n\u003Cp>The practical takeaway is to confirm that your client and server versions stay within the supported skew rules before you upgrade. If you skip that step, you can end up with a cluster that is technically running but awkward to manage.\u003C\u002Fp>\n\u003Ccode>Check: kubectl version\u003C\u002Fcode>\n\u003Ch2>How to decide\u003C\u002Fh2>\n\u003Cp>If you want the safest default, run one of the three supported minors and stay on the latest patch within that branch. If your team upgrades often, the release-cycle view matters most. If you manage older clusters, the support-window dates are the signal that tells you when a migration is overdue.\u003C\u002Fp>\n\u003Cp>For most readers, the best choice is the newest supported minor with current patches. For teams planning upgrades, the table is the fastest way to see how much time is left on each branch and which releases are already past active support.\u003C\u002Fp>","Kubernetes’ release support
