   * `[sitecore-jss-react]` Introduces `PlaceholderMetadata` component which supports the hydration of chromes on Pages by rendering  the components and placeholders with required metadata.
   * `[sitecore-jss]` Chromes are hydrated based on the basis of new `editMode` property derived from LayoutData, which is defined as an enum consisting of `metadata` and `chromes`.
   * `ComponentConsumerProps` is removed. You might need to reuse `WithSitecoreContextProps` type.
@@ -45,6 +45,7 @@ Our versioning strategy is as follows:
   * `[sitecore-jss]` Introduced `GraphQLEditingService` class to fetch editing data in Metadata Edit Mode.
   * `[templates/nextjs-xmcloud]` Introduced _/lib/graphql-editing-service_ to fetch editing data in Metadata Edit Mode.
   * `[templates/nextjs-xmcloud]` Added a new _page-props-factory/plugins/preview-mode_ plugin to handle both Chromes and Metadata Edit Mode.
+  * `[sitecore-jss]` layout-personalizer will mark components hidden by personalization by setting 'Hidden Rendering' component name in Metadata edit mode
 * `[sitecore-jss]` Introduced _/editing_ submodule that contains all editing related functionality. Editing utils are now available in _/editing_ submodule. Editing utils exported from _/utils_ marked as deprecated. ([#1806](https://github.com/Sitecore/jss/pull/1806))
 * `[sitecore-jss-nextjs]` EditingRenderMiddleware `resolvePageUrl` function now accepts an object `(args: { serverUrl?: string; itemPath: string }) => string` instead of multiple parameters `(serverUrl: string, itemPath: string) => string`. `serverUrl` is now optional and omitted when Metadata Edit Mode is used.
 * `[templates/nextjs]` `[sitecore-jss-nextjs]` `[sitecore-jss]` Remove Partial rendering implementation as it will not be used by Pages in its current implementation - includes removing of EditingComponentPlaceholder component, few constants associated with it and RenderingType enum ([#1821](https://github.com/Sitecore/jss/pull/1821))
