11The previous default width of 300 vp for the linear style of the **Progress** component does not align with the UX specifications.

13**Change Impact**

15This change is a non-compatible change. With this change, the default width of the linear style of the **Progress** component will now adapt to the width of its parent component, offering increased flexibility.

37After this change, if the width of the **Progress** component in linear style does not meet your requirements, you can manually set the [width](../../../application-dev/reference/apis-arkui/arkui-ts/ts-universal-attributes-size.md#width) attribute to achieve the desired layout.
