+> ⚠️ The default value for `order` changed from `"legacy"` to `"sort-package-json"` in v0.6.0.
 
 This rule is **autofixable**; run `eslint` with the `--fix` option to sort top-level properties in place.
 Any properties not present in the array of ordered properties will be left in their original positions.
