Description

About v1.2.0

Verbatims from @MaximeTonnerre below:

 
**Version 2.7 of the design tokens is required for the development of this update.**

- Removal of the “Video” variant in leading and trailing positions.
- For the nested “Image” component, addition of a new boolean variant, “Animated=True/False”, allowing the use of animated images in GIF or WEBP formats.

Bug fix
- The “Icon”, “Image”, and “Avatar” assets in the trailing position of the “Size: Small” / “Alignment: Top alignment” variants no longer offer “Medium/Large” sizes.
- Updated size tokens applied to “Icon” assets:
    * Size “Small”: size/icon/with-label/large/size-small
    * Size “Medium”: size/icon/with-label/large/size-medium
    * Size “Large”: size/icon/with-label/large/size-xlarge
- Flag sizes have been updated for the “Small” and “Default” variants:
    * Removal of the height token: list-item/size/flag/height
    * To replace it with the width tokens:
        - Size “Small”: ouds/control/list-item/size/asset/small
        - Size “Medium”: ouds/control/list-item/size/asset/medium
