 ### New Features {#new-features-2-2-0}
-* Adds support for using custom domains to alias the replicated.app and proxy.replicated.com endpoints in Embedded Cluster installations. To use custom domains, first add your custom domains in the Vendor Portal, then set `domains.proxyRegistryDomain` and `domains.replicatedAppDomain` in the Embedded Cluster Config. For more information, see [Configure Embedded Cluster to Use Custom Domains](/vendor/custom-domains-using#ec).
+* Adds support for using custom domains to alias the replicated.app and proxy.replicated.com endpoints in Embedded Cluster installations. To use custom domains, first add your custom domains in the Vendor Portal, then set `spec.domains.proxyRegistryDomain` and `spec.domains.replicatedAppDomain` in the Embedded Cluster Config. For more information, see [Configure Embedded Cluster to Use Custom Domains](/vendor/custom-domains-using#ec).
 * Removes all calls to endpoints other than replicated.app and proxy.replicated.com (or the configured custom domains for these endpoints). This simplifies the process for enterprises to deploy Embedded Cluster by minimizing the number of endpoints to whitelist.
