 ### New default value for automatic redirects
 
-To improve performance, the default value for `generate_category_product_rewrites` in the [`app/code/Magento/CatalogURLRewrite/etc/config.xml`](https://github.com/magento/magento2/blob/2.4-develop/app/code/Magento/CatalogUrlRewrite/etc/config.xml#L12) file was changed from `1` to `0`. This change disables [automatic redirects](https://experienceleague.adobe.com/docs/commerce-admin/marketing/seo/url-rewrites/url-redirect-product-automatic.html) by default.

This change disables [automatic category/product URL rewrites](https://experienceleague.adobe.com/docs/commerce-admin/marketing/seo/url-rewrites/url-redirect-product-automatic.html#skip-rewrite), but only if you have not changed the previous default setting prior to upgrading to 2.4.6.
 
-The new default does not change existing records in the `catalog_url_rewrite_product_category` and `url_rewrite` database tables when upgrading to 2.4.6, but no new rewrites are added. However, using the `bin/magento config:set catalog/seo/generate_category_product_rewrites` command to change this configuration setting after upgrading to 2.4.6 permanently deletes all rewrites with no ability to restore them. This may cause unresolved "category/product" type URL conflicts that you must resolve by manually updating URL keys.

You can enable the **Generate "category/product" URL Rewrites** setting if you want to continue using it after upgrading.
