• Relaxing the version requirement to '0' may allow for unintentional dependency updates; please verify that this version syntax meets the intended constraint for stable releases.

+k8s-openapi = { version = "0", default-features = false }

Cargo.toml:25

• Ensure that setting the version to '0' in dev-dependencies does not introduce unexpected behavior, as it may similarly allow for a broader range of versions than intended.

+k8s-openapi = { version = "0", default-features = false, features = ["latest"] }
