If you're adding new variants to products you might find yourself in a situation where some variants of a product don't have a SKU set. You can now use the new "Product's first tag" placeholder to set these variants to have the same SKU as the other variants for a product.
When editing the SKU field just select "Product' first tag" from the "Add Placeholder" dropdown. This will set each variant's SKU to be the first non-blank SKU from you product.
