+## Upgrading to Helm chart version 4.2.0 (not released yet)
+
+### TLS configuration for ZooKeeper has changed
+
+The TLS configuration for ZooKeeper has been changed to fix certificate and private key expiration issues.
+This change impacts configurations that have `tls.enabled` and `tls.zookeeper.enabled` set in `values.yaml`.
+The revised solution requires the `AdditionalCertificateOutputFormats=true` feature gate to be enabled in the `cert-manager` deployment when using cert-manager versions below 1.15.0.
+If you installed `cert-manager` using `./scripts/cert-manager/install-cert-manager.sh`, you can re-run the updated script to set the feature gate. The script currently installs or upgrades cert-manager LTS version 1.12.17, where the feature gate must be explicitly enabled.
+
 ## Upgrading from Helm Chart versions before 4.0.0 to 4.0.0 version and above
 
 ### Pulsar Proxy service's default type has been changed from `LoadBalancer` to `ClusterIP`
