+title: Altering config entries
+---
+
+Starting from Home Assistant 2024.3, modifications to a `ConfigEntry` should use `hass.config_entries.async_update_entry`.
+Directly setting attributes on the `ConfigEntry` object is deprecated and will start to fail in version 2024.9 and later.
+There is no deprecation period for directly setting `unique_id` on the `ConfigEntry` as doing so will corrupt the internal state, and doing so will start to fail immediately.
+
+The following attributes must now be set via `hass.config_entries.async_update_entry`:
+
+- data
+- minor_version
+- options
+- pref_disable_new_entities
+- pref_disable_polling
+- title
+- unique_id
+- version
+
+Tests must ensure that `MockConfigEntry` objects are added to Home Assistant via `entry.add_to_hass(hass)` before calling `hass.config_entries.async_update_entry`.
