### Feature Gates

| Name | Default Value | Description |
|-----------------------------|---------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `AllowDNSLookups` | `false` | Allows the controller to perform DNS lookups when rendering Helm templates. This is disabled by default, as it can be a security risk. |
| `CacheSecretsAndConfigMaps` | `false` | Configures the caching of Secrets and ConfigMaps by the controller-runtime client. When enabled, it will cache both object types, resulting in increased memory usage and cluster-wide RBAC permissions (list and watch). |
| `OOMWatch` | `false` | Enables the OOM watcher, which will gracefully shut down the controller when the memory usage exceeds the configured limit. This is disabled by default. |

| `AdoptLegacyReleases` | `true` | Enables the adoption of the historical Helm release based on the status fields from a v2beta1 HelmRelease object. This is enabled by default to support an upgrade path from v2beta1 to v2beta2 without the need to upgrade the Helm release. |
