v1.19

WARNING!
Universal Analytics / GA3 ecommerce events deprecated!
Please update your GTM setup so that it does not rely on any of the following GTM4WP events and the old ecommerce data layer:

• gtm4wp.productClickEEC
• gtm4wp.addProductToCartEEC
• gtm4wp.removeFromCartEEC
• gtm4wp.checkoutOptionEEC
• gtm4wp.checkoutStepEEC
• gtm4wp.changeDetailViewEEC
• gtm4wp.orderCompletedEEC

Instead of the above events, you can use the new GA4 ecommerce events (add_to_cart, purchase, etc.)
In the Universal Analytics GTM tag now you have an option to use the GA4 ecommerce data in the data layer.
If you are on GA360 and still collecting ecommerce data, you need to update your GTM setup to use that option firing on the GA4 ecommerce events.

• Updated: WooCommerce integration now accepts the primary category selection of Yoast SEO and Rank Math SEO
• Updated: use the gtm4wp_admin_page_capability filter to modify the capability needed to use the admin page (thanks emreerkan)
• Fixed: price did not include the .00 postfix for integers in the add_to_cart event
• Added: if needed, you can turn on clearing the ecommerce object before a new GA4 event is being pushed.
• Added: support for Google Consent Mode default command for use cases where the consent management tool does not support it already

v1.18.1

• Fixed: PHP notice about Undefined variable: blocking_cookie

v1.18
