WooCommerce 9.9: It’s fast, period.

9.9 is fast, period.

This version includes big improvements to performance. We’ve measured up to 95% reductions in page load times across critical admin screens. We ran benchmarking using a store with:

• >1.2 million orders
• 15,000 products
• 60,000 customers
• HPOS enabled

We compared WooCommerce 9.7 as the baseline against 9.9 and saw improvements across every corner of the admin, from order count summaries and comment tallies to custom-field lookups and analytics widgets. Read more about how we achieved these big gains.

New block: Product filters

The new Product filters block is powered by the Interactivity API for faster filtering without page reloads.

Optimized for mobile, filters appear in a modal for a cleaner browsing experience. The block is also context-aware and works seamlessly inside Product Collection blocks, returning accurate results that don’t require reloading the page.

Selective product exports

You can now export specific products and their variations directly from the product list using product IDs. This makes bulk editing faster and more efficient, especially for high-volume stores. It removes the need for full exports when only a subset of products needs updating.

Developers can also hook into the export process to define custom product ID lists programmatically for even greater control.

function my_filter_product_export_by_ids( $args ) {
    $my_product_ids_to_export = array( 10, 20, 30 ); // Define your list of product IDs
 
    // Set the 'include' argument to your specific list.
    // This tells wc_get_products to fetch only these products.
    $args['include'] = $my_product_ids_to_export;
    return $args;
}
 
add_filter( 'woocommerce_product_export_product_query_args', 'my_filter_product_export_by_ids' );

Automatic database updates

All stores as of 9.9 will now run database updates and migrations automatically in the background. This reduces friction in the update process, especially for multi-site or managed environments. Developers can still opt out using the filter: woocommerce_enable_auto_update_db.

Conditional checkout fields

This version introduces the ability to conditionally collect additional information during checkout using the Additional fields API. With support for JSON schema, you can define field visibility, required status, and validation rules directly in PHP. Validation runs on both the server and client sides, and hidden fields are neither shown to customers nor submitted, ensuring only relevant data is collected.

Field visibility can be based on dynamic conditions such as cart contents, order details, or customer information and preferences.

To learn how to implement this, see our documentation on conditional fields.
