2026.10.16 – version 2.9.5
* Fix: Harden child item validation. Child items cannot be modified independently of their container. #615.
* Update: 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”.
* Fix: 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.
* Fix: 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`.
* Fix: Child item quantity steppers in the Add to Cart + Options block were labelled with the container product name instead of the child product name.
* Fix: 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.
* Update: Note in the “Display plus/minus buttons” Customizer setting description that it has no effect in the Add to Cart + Options block.
* Fix: Hide child item prices in the Cart block when the container is fixed-price.
