For Home Assistant Core 2023.2 the database schema has changed.
This change affects custom integrations that do not use the recorder history API and access the last_updated, last_changed, or time_fired columns directly.
The documentation for the events and states have been updated and is available at the Data Science Portal.
Integrations that need to use a Bluetooth adapter should add bluetooth_adapters in dependencies in their manifest.json.
The DataUpdateCoordinator can now reduce unnecessary updates when API data can be compared.
The method for integrations to provide translations for states of its entities under other integrations, for example to translate an integration's sensors has changed.
Some changes have been made to the long-term statistics-related APIs to reduce response size and database load.
