 All notable changes to the CasaOS fork installer are documented here.
 
+## [0.5.13] - 2026-09-27
+
+Components: CasaOS-AppManagement `v0.4.68`. Unchanged from v0.5.12: CasaOS `v0.4.63`, CasaOS-UI `v0.4.77`, CasaOS-UserService `v0.4.30`, CasaOS-MessageBus `v0.4.29`, CasaOS-LocalStorage `v0.4.44`, CasaOS-Gateway `v0.4.30`, Common `v0.4.27`, rclone `v1.75.1`.

+### Fixed

+- **No more "Could not check" for an app built on the box.** An app whose services are all built on the box, like an app deployed from git, runs nothing a registry publishes. The app update check listed it as an app it could not check after every run; it now leaves it out.
+- **An app written by hand shows its image.** A compose file without `x-casaos` reached the dashboard without its image, so the dashboard could not recognise what it runs.

 - **In the dashboard**: the *Anonymous usage statistics* switch in the settings. It takes effect at once.
 - **By hand**: stop the core (`sudo systemctl stop casaos`), set `"enabled": false` in `/var/lib/casaos/telemetry.json` (or create the file holding `{"enabled": false}` if it is not there yet), and start it again (`sudo systemctl start casaos`).
 
+## What is in v0.5.13
+
+**Quieter update checks.** An app built on the box, such as one deployed from git, is no longer reported as an app the update check could not check.

 ## What is in v0.5.12
 
 **A tidier dashboard.** The settings panel is grouped and compact, and the backup, alert, update, system package and git dialogs share one clean layout, readable in both themes and on a phone.
