Security and upgrade priorities
WooCommerce core
The release index marks WooCommerce 11.0.1, released on 2026-08-10, as stable. Only the latest core version is considered fully secure.
Do not treat downloadable legacy point-release packages as evidence that a fully secure supported branch exists.
Stripe for WooCommerce
Update Stripe for WooCommerce to the latest available release to receive the August 2026 security update.
Patched Stripe for WooCommerce releases also correct a payment-validation issue that affects some stores using Adaptive Pricing. Upgrade affected stores to a patched release.
WooCommerce Subscriptions
Update every production and staging site that runs WooCommerce Subscriptions to version 9.1.0.
PayPal Standard
PayPal Standard is sunsetting. Plan a migration away from it using the upgrade path available in PayPal 4.1.0.
WooCommerce 11.0 integration changes
Reserved order-item meta in the admin
WooCommerce 11.0.0 no longer persists reserved order-item meta keys entered through the admin Add meta button.
Admin tooling must use non-reserved keys for custom order-item data.
Removed order-item lifecycle
WooCommerce 11.0.0 changes when woocommerce_removed_order_items runs while
deferring order-item database deletion until save().
Integrations that observe removed items must account for the new save-time lifecycle.
Failed-order stock restoration
Starting in WooCommerce 11.0, moving an order to failed restores stock that
the order previously reduced.
Custom order and inventory handlers must not duplicate that restock.
Shop page queried object
In WooCommerce 11.0, get_queried_object() on the Shop page returns a
WP_Post rather than a WP_Post_Type.
Update type checks and property access that assumed the previous object type.
Product shipping classes
WooCommerce 11.0 makes the product_shipping_class taxonomy non-public.
Extensions must not rely on that taxonomy being publicly exposed.
Product editor beta removal
WooCommerce 10.9 begins the final deprecation window for the product editor beta. The beta editor is removed in 11.0, and stores continue with the classic product editor.
Extensions must not depend on the beta editor remaining available after 11.0.
Capability boundaries
Core COGS and MCP beta
WooCommerce 10.3.0 is the release where cost of goods sold came to core and MCP entered beta.
Use 10.3.0 as the compatibility boundary for integrations that depend on those capabilities.
Interactivity API Mini-Cart
WooCommerce 10.4.0 is the release where the Interactivity API Mini-Cart went live.
Test theme and extension compatibility for that Mini-Cart implementation against 10.4.0 or newer.
Email previews
WooCommerce 9.8.0 introduced email previews alongside modernized designs.
Use 9.8.0 as the minimum release when relying on the preview workflow.
Compatibility checklist
Core and store administration
- Treat only the latest WooCommerce core version as fully secure.
- Treat legacy point releases as downloadable packages, not proof of a fully secure supported branch.
- Use non-reserved keys when admin tooling adds custom order-item data.
- Do not depend on the product editor beta after WooCommerce 11.0.
Order and inventory integrations
- Account for the save-time lifecycle around
woocommerce_removed_order_itemsand deferred database deletion. - Do not restock a second time when moving a stock-reducing order to
failedunder WooCommerce 11.0 or newer.
Themes and extensions
- Expect a
WP_Postfromget_queried_object()on the Shop page under WooCommerce 11.0. - Do not rely on public exposure of the
product_shipping_classtaxonomy under WooCommerce 11.0. - Test Interactivity API Mini-Cart compatibility against WooCommerce 10.4.0 or newer.
Capability-dependent integrations
- Use WooCommerce 10.3.0 as the boundary for core cost of goods sold and the MCP beta.
- Require WooCommerce 9.8.0 when relying on the email preview workflow.
Payment and subscription extensions
- Update Stripe for WooCommerce to the latest available release for the August 2026 security update.
- Upgrade affected Adaptive Pricing stores to a Stripe for WooCommerce release containing the payment-validation patch.
- Update WooCommerce Subscriptions to 9.1.0 on production and staging sites.
- Plan migration away from PayPal Standard through the path in PayPal 4.1.0.
