 All notable changes to the CasaOS fork installer are documented here.
 
+## [0.5.11] - 2026-09-25
+
+Components: CasaOS-MessageBus `v0.4.29`. Unchanged from v0.5.10: CasaOS `v0.4.63`, CasaOS-AppManagement `v0.4.67`, CasaOS-UI `v0.4.76`, CasaOS-UserService `v0.4.30`, CasaOS-LocalStorage `v0.4.44`, CasaOS-Gateway `v0.4.30`, Common `v0.4.27`, rclone `v1.75.1`.
+
+### Fixed
+
+- **Push alerts stayed silent after the core restarted.** When several listeners left the message bus at once, the bus could lock itself up: every listener that came after it was connected but never received anything. The alerts of v0.5.10 were the first to notice, as the core listens again each time it restarts. The bus also no longer drops an event that arrives while it is busy with another.

 - **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 v0.5.11

+**Push alerts that arrive.** A fix in the message bus: the alerts of v0.5.10 could stay silent after the core restarted.

 ## What is in v0.5.10
 
 **Push alerts.** A failed backup, a failing or full disk, a crashed app or an update that paused now reaches your phone or your mail box (ntfy, Telegram, e-mail, Discord and others). Add a channel under *Alerts* in the settings.
