Product Specifications
The Product Specification visibleSpecifications and hiddenSpecifications props can now be edited through the admin's Site Editor.

Main advantages
Whenever a component, such as Product Specification, gains the flexibility to be editable (whether in part or in full) using Site Editor, retailers become independent from the source code and are able to configure their stores as desired.
What you need to do
Make sure you store is already running Store Components version 3.85.0 or higher.
