 The [Datetime Range module](https://www.drupal.org/node/2893128) provides a
 field type that allows end dates to support contributed modules like
-[Calendar](https://www.drupal.org/project/calendar).
+[Calendar](https://www.drupal.org/project/calendar). This stable release is
+backwards-compatible with the 8.3.x experimental version and shares a
+consistent API with other Datetime fields.
+
+Future releases may improve Views support, usability, and Datetime Range field
+validation. For bugs or feature requests for this module, [see the core
+Datetime issue queue](https://www.drupal.org/project/issues/search/drupal?project_issue_followers=&status%5B%5D=Open&version%5B%5D=8.x&component%5B%5D=datetime.module&issue_tags_op=%3D).
 
 ### Media
 
-The [Media module]() provides an API for reusable media entities and references
-based on the contributed [Media entity module](). The API and data model are
-stable, so developers and expert site builders can add Media as a dependency.
-However, the module has numerous user experience issues, so it is *hidden*
-and will not appear on the 'Extend' (module administration) page. (Enabling a
-contributed module that depends on the Media module will also enable the
-Media automatically.) The module will be displayed to site builders normally
-once the user experience issues are resolved in a future release.
+The new core [Media module](https://www.drupal.org/node/2895059) provides an
+API for reusable media entities and references based on the contributed
+[Media entity module](https://www.drupal.org/project/media_entity).
+
+Since there is a rich ecosystem of Drupal contributed modules built on Media
+Entity, the top priority for this release is to provide a stable core API and
+data model for these modules. Developers and expert site builders can add
+Media as a dependency. Work is underway to [provide an update path for
+existing sites' Media Entity data](https://www.drupal.org/node/2880334) and to
+[port existing contributed modules to the refined core API](https://www.drupal.org/node/2860796).
+
+Note that **the core Media module is currently marked hidden** and will not
+appear on the 'Extend' (module administration) page. (Enabling a contributed
+module that depends on the core Media module will also enable the Media
+automatically.) The module will be displayed to site builders normally once
+user experience issues with it are resolved in a future release.
