+#### Api4 Extension now included
+The [Api v4 extension](https://github.com/civicrm/org.civicrm.api4) is now included in the CiviCRM download.
+It provides the latest version of CiviCRM's api for integration with extensions and other software; is is still under active development but considered complete enough to use.
+Because it is not yet used by CiviCRM core, it is disabled by default.
+If you install an extension which requires this api, it will be enabled automatically.
