This update introduces breaking changes by marking the 'name' and 'parent' parameters as strictly required across the API surface. Developers must ensure these fields are included in their requests to avoid validation errors. Additionally, the 'shelves.get' method has been formally added, and the API now supports standard Google Cloud global query parameters such as 'fields', 'prettyPrint', and 'quotaUser'. The update also includes mTLS support via a new root URL: https://libraryagent.mtls.googleapis.com/.
