+## Solr no longer indexes draft/restricted content {#solr-updates}
+
+At the time of this release a new version of the popular [silverstripe/fulltextsearch module](https://github.com/silverstripe/silverstripe-fulltextsearch) is also available, introducing more secure defaults. Most notably, draft and restricted content will no longer be indexed by default, due to a `canView()` check being performed against an anonymous user prior to (re)indexing. Restricted content means that it has a permission level of either 'Logged-in users' or 'Only these groups'.
+
+If your project uses this module, after upgrading your website, ensure that you run the `Solr_Reindex` task on your production environment to remove previously indexed content that should no longer be there.
+
+If your website requires draft or restricted content to be indexed, you can opt-out of the new secure defaults on a per-model basis.
+
+This is a great opportunity to make sure that any custom indexes/search controllers in your project are correctly filtering results based on permissions and search visibility, which you can now achieve via a unified method (see `SilverStripe\FullTextSearch\Search\Services\SearchableService::isSearchable()`.)
+
+The [silverstripe/fulltextsearch module readme provides additional information](https://github.com/silverstripe/silverstripe-fulltextsearch).
