+There is a breaking change introduced in the [YAML 1.2](https://yaml.org/spec/1.2.0/#id2602744)
+boolean values specification with respect to [YAML 1.1](https://yaml.org/spec/1.1/#id864510).
+This is a known [issue](https://github.com/kubernetes/kubernetes/issues/34146) in Kubernetes.
+YAML 1.2 only recognizes **true** and **false** as valid booleans, while YAML 1.1 also accepts
+**yes**, **no**, **on**, and  **off** as booleans. However, Kubernetes uses YAML
+[parsers](https://github.com/kubernetes/kubernetes/issues/34146#issuecomment-252692024) that are
+mostly compatible with YAML 1.1, which means that using **yes** or **no** instead of **true** or
+**false** in a YAML manifest may cause unexpected errors or behaviors. To avoid this issue, it is
+recommended to always use **true** or **false** for boolean values in YAML manifests, and to quote
+any strings that may be confused with booleans, such as **"yes"** or **"no"**.
+
+Besides booleans, there are additional specifications changes between YAML versions. Please refer
+to the [YAML Specification Changes](https://spec.yaml.io/main/spec/1.2.2/ext/changes) documentation
+for a comprehensive list.
