Cloud and DevOps tooling has some of the shortest support windows in the software ecosystem. Kubernetes releases a new minor version every four months and supports each version for approximately fourteen months. Teams that do not actively track Kubernetes versions frequently find themselves running unsupported clusters.
The cloud-native ecosystem moves faster than any other software category. Kubernetes, Helm, Terraform, and related tools follow aggressive release cadences with short support windows. A Kubernetes version that was current eighteen months ago may already be past end of life — and clusters running EOL Kubernetes versions miss security patches for control plane components, admission webhooks, and networking plugins.
Kubernetes 1.26 through 1.31 are all past end of life as of mid-2026. Each of these versions had a fourteen-month support window. Teams running managed Kubernetes services — EKS, GKE, AKS — benefit from vendor-extended support but should verify their specific version status with their cloud provider.
Infrastructure-as-code tools like Terraform and Ansible have longer support windows but still require active lifecycle tracking. The HashiCorp licensing change in 2023 also means teams should evaluate whether OpenTofu is appropriate for their environment.
