+title: Release 0.11
+---
+
+This update brings these headline features:
+
+-   Add Backup and Restore, currently only externally schedulable, documented [here](../maintenance/backups/index.md)
+-   New Admin Dashboard with more metrics and Charts
+
+    Shows successful and failed logins from the last 24 hours, as well as the most used applications
+
+-   Add search to all table views
+-   Outpost now supports a Docker Controller, which installs the Outpost on the same host as authentik, updates and manages it
+-   Add Token Identifier
+
+    Tokens now have an identifier which is used to reference to them, so the Primary key is not shown in URLs
+
+-   `core/applications/list` API now shows applications the user has access to via policies
+
+## Upgrading
+
+This upgrade can be done as with minor upgrades, the only external change is the new docker-compose file, which enabled the Docker Integration for Outposts. To use this feature, please download the latest docker-compose from [here](https://raw.githubusercontent.com/BeryJu/authentik/master/docker-compose.yml).
+
+Afterwards, you can simply run `docker-compose up -d` and then the normal upgrade command of `docker-compose run --rm server migrate`.
