+title: "Changes to the update entity"
+---
+
+### Summary of changes
+
+The `update` entity has been adjusted:
+- The `in_progress` property and the corresponding state attribute should now only be a `bool` indicating if an update is in progress, or `None` if unknown.
+- A new property and a corresponding state attribute `update_percentage` has been added which can either return an `int` or `float` indicating the progress from 0 to 100% or None.
+- A new property and a corresponding state attribute `display_precision` has been added to control the number of decimals to display in the frontend when `update_percentage` is a `float`.
+
+### Backwards compatibility
+
+Until Home Assistant Core 2025.12, a numerical value in the `in_progress` property will be automatically copied to the `update_percentage` state attribute.
+
+### Documentation and core implementation
+
+See the [update entity developer documentation](https://developers.home-assistant.io/docs/core/entity/update) for details.
