Change log:

[3.14.0] - TBC

Added

• Add chart option to permit setting hostUsers for additional isolation. (#1751) @jcpunk
• Add namespaceOverride which allows deploying to a namespace other than .Release.namespace. (#1711) @TheRealNoob

Changed

• Apply tls.certManager.annotations and tls.certManager.labels to the Cert Manager Certificate resource; these values are documented but were previously never rendered. (#1825) @yugstar
• Use metrics-server.fullname instead of metrics-server.name for ClusterRole. (#1801) @yesdeepakverma
• Update the Metrics Server OCI image to 0.9.0. (#1846) @stevehipwell

Fixed

• Stop rendering annotations: null on the cert-manager Issuer, which referenced an undefined additionalAnnotations value. This mirrors the earlier APIService fix and prevents permanent GitOps OutOfSync. (#1825) @yugstar
