有訂 RSS feed 但應該是漏看了，後來在 X (Twitter) 上看到 qrtt1 轉貼 ingramchen 的貼文才注意到的，AWS 宣布 EKS 支援期從本來的 14 個月 (跟 k8s 官方相同) 變成 26 個月 (多了一年)：

公告在「Amazon EKS Extended support for Kubernetes Versions now available in preview」以及「Amazon EKS extended support for Kubernetes versions available in preview」這邊。
這邊查了資料發現有點複雜，KEP-2572: Defining the Kubernetes Release Cadence 這邊有正式的說明，但「Kubernetes | endoflife.date」這邊比較清楚 14 個月是怎麼來的：
Kubernetes follows an N-2 support policy (meaning that the 3 most recent minor versions receive security and bug fixes) along with a 15-week release cycle. This results in a release being supported for 14 months (12 months of support and 2 months of upgrade period).
雖然是付費功能，但目前這個功能是 preview，代表不受到 SLA 之類的保障，應該是之後成熟了再看情況變成 GA：
Today, we’re announcing the preview of Amazon Elastic Kubernetes Service (EKS) extended support for Kubernetes versions. You can now run Amazon EKS clusters on a Kubernetes version for up to 26 months from the time the version is generally available on Amazon EKS. Extended Support is available as a free preview for all Amazon EKS customers, starting today with Kubernetes version 1.23.
算是還不錯的消息？就目前看到的經驗，每次的升級都會爛掉不少東西，所以沒用到新功能卻被迫要更新的次數可以降低一些，總是好事...
