- Describing the CRs will now hide `.metadata.managedFields` ([#114584](https://github.com/kubernetes/kubernetes/pull/114584), [@soltysh](https://github.com/soltysh))
- Discovery document will correctly return the resources for aggregated apiservers that do not implement aggregated disovery ([#115770](https://github.com/kubernetes/kubernetes/pull/115770), [@Jefftree](https://github.com/Jefftree))

        * `password`: some next chapters will cover examples of this.
* `openIdConnect`: has a way to define how to discover OAuth2 authentication data automatically.
    * This automatic discovery is what is defined in the OpenID Connect specification.

## Authentication

The agent supports two forms of authentication with the CA/discovery servers: mTLS and JWT. Varying deployment
topologies mix and match these two.

For a standard Kubernetes deployment, both CA and discovery will use JWT authentication, with a token automatically

h3. Discovery all Plexus components

Once the ClassRealm is populated with the plugin artifact and its dependency artifacts a discovery operation must be performed on the plugin ClassRealm in order to discover any Plexus components that may be present in any of the artifacts required for the plugins execution.
