Preserve line properties in CartLinesUpdate mutation
API
Effective June 13, 2024
The CartLinesUpdate mutation behavior has been updated to preserve existing line properties when the attributes parameter is either omitted or explicitly set to null.
Previously, omitting the attributes parameter would reset the line properties. Passing an empty hash { } to reset line properties is an existing capability and remains unchanged.
