-Check what's new in the latest version and potentially impacts your system in [Home Assistant release notes](https://github.com/home-assistant/home-assistant/releases). It is good practice to review these release notes and pay close attention to the **Breaking Changes** that are listed there. If you haven't done an update for a while, you should also check previous release notes as they can also contain relevant **Breaking Changes**. **Breaking Changes** may require configuration updates for your components. If you missed this and Home Assistant refuses to start, check the log file in the [configuration](/docs/configuration/) directory, e.g., `.homeassistant/home-assistant.log`, for details about broken components.
