The latest XM Cloud base image includes the following fixes:
If you have the same component (rendering) added to both a shared and final layout, the dynamic placeholder IDs are now unique for each component instance. Previously, the placeholders on such components shared the same identifier, so that a component added to the placeholder in one layout also appeared in the other.
The x-default URL is now generated correctly in the default site language. Previously, it was generated in the first language defined in the language grouping (usually English).
