WooCommerce Mix and Match Products v2.9.6

WooCommerce Mix and Match Products v2.9.6
2026.11.03 - version 2.9.6
* Update: Tested up to WooCommerce 11.2.0.
* Fix: "Undefined array key" warnings in `cart_shipping_packages()` when WooCommerce Multilingual translates the cart after a language switch, or whenever child items change keys or leave the cart during a request. Child items were left out of the container's shipping weight and value for that calculation. `wc_mnm_get_child_cart_items()` and `wc_mnm_get_cart_item_container()` no longer cache their results, so they always reflect the current cart contents.
* Fix: Container cart validation could miss child items that were removed from the cart earlier in the same request.
* Fix: Remove debugging output from the "Some items you have selected are no longer available" notice.
* Fix: Fatal error after updating from 2.9.4 or earlier when PHP OPcache still held the old autoloader, which pointed to the Not Sold Separately feature's previous location in `includes/features/not-sold-separately/`. Stub files at the old paths now load the classes from `src/Features/NotSoldSeparately/`.

WooCommerce Mix and Match Products v2.9.5
Changelogs =

• New wc_mnm_has_plus_minus_buttons() template function to check whether plus/minus buttons are enabled, filterable via wc_mnm_has_plus_minus_buttons. Updated template single-product/mnm/mnm-product-quantity.php.

Improved

• The Store API errors when removing a child item or changing its quantity now name the child product and its container instead of "This product".
• Note in the "Display plus/minus buttons" Customizer setting description that it has no effect in the Add to Cart + Options block.
• Astra and Flatsome compatibility modules now disable plus/minus buttons via the wc_mnm_has_plus_minus_buttons filter instead of pre_option_wc_mnm_display_plus_minus_buttons.

Fixed

• Harden child item validation. Child items cannot be modified independently of their container. #615.
• Stale container returned by wc_mnm_get_cart_item_container() after the container was removed from the cart. The cart is now checked for the container before the cached value is used.
• Give child item checkbox inputs a custom ID attribute to prevent plus/minus buttons and a border by the Add to Cart + Options block. Updated template single-product/mnm/mnm-product-quantity.php.
• Child item quantity steppers in the Add to Cart + Options block were labelled with the container product name instead of the child product name.
• Duplicate plus/minus buttons on child item quantity inputs in the Add to Cart + Options block. As of WooCommerce 10.8 the block adds its own quantity steppers, so Mix and Match's plus/minus buttons are now disabled inside the block regardless of the "Display plus/minus buttons" Customizer setting. The classic add to cart form is unaffected. #543.
• Hide child item prices in the Cart block when the container is fixed-price.
• Suppress "removed from your cart" notices for child items in the Cart block when their container is removed. Requires WooCommerce 9.5.2+. The Mini-Cart block does not yet support suppressing these notices.

WooCommerce Mix and Match Products v2.9.4
* Fix: Incorrect "cannot be removed independently" error when attempting to remove container from cart block. #614.

WooCommerce Mix and Match Products v2.9.3
