Shopify treats tags as case-insensitive, so a product can’t have both Jewelry and jewelry at the same time. We’ve improved how tag edits work with these case differences.
When you add a tag that already exists on a product in a different case, the casing you add is now the one that sticks. Eg adding jewelry to a product tagged Jewelry updates the tag to jewelry. This is a good way to clean up tag casing across your catalog, since casing can show up in places like collection pages and storefront filtering.
Undo is also smarter about casing now. Undoing an edit that only changed a tag’s case restores the original casing, and undoing a tag removal brings the tag back with its exact original casing, even if a case-variant of it was added in the meantime. Tags that aren’t part of the undo are left alone.
