Automate WooCommerce 6.0.20

New - Action: Subscription Add Note
New - Variables: customer.username and order.subtotal
New - Added background trigger activity logs. Logs show when a process is started, continued and finished
New - Added a regex comparison option for all string rules and meta rules
New - Added support for workflow variables in price fields
New - Implemented AJAX search for coupons rules instead of loading all coupons at once
New - The customer.generate_coupon variable builder now uses a searchable coupon field - no more having to copy and paste coupon codes!
New - Improved performance by adding object caching to all custom table meta values
New - Customer order count and total spend for registered users now includes guest orders made by the same billing email. We also optimized the database queries to retrieve these values and adding caching to improve performance.
New - Improved support for localized price formats. If you are expecting non-localized prices be sure to double check your workflows.
Tweak - Remove pre WooCommerce 3.0 legacy code. Our minimum required version is still 3.0
Tweak - We've removed the subscription payment complete trigger from the manual trigger tool to avoid confusion about how it works. In the not too distant future we’ll handle this better with a new manual workflows feature.
Tweak - Moved to using a single customer meta data table. Previously customer meta data was split between 2 tables, either in the WP user meta table when the customer was registered or in the AW guest meta table when the customer was a guest.
Tweak - We now cast all workflow variables including the meta variable as strings - this fixes an issue where handling of array or object meta fields would cause unexpected results.
Tweak - Because product reviews can not be added to product variations we have modified our product review templates to convert product variations to parent products
Fix - Bug where workflows could run with missing or trashed data items.
Fix - Ensure that users prior orders when placed as guest are now considered by the "Order - Is Customer's" First rule
Fix - Disabled workflows are now visible in the "all" view of the admin list table
Fix - Rare issue where rules could fail to load correctly depending on the order they were used
Fix - We no longer set session tracking cookies on admin requests. Cookies will be set as normal by WooCommerce and AutomateWoo ajax requests (e.g. checkout, add to cart) since they aren't routed via admin ajax.
Fix - Improved reliability of AutomateWoo Cron scheduling and handling of day light saving timezone changes.
Fix - The order.date_shipped variable now displays a human readable date instead of a timestamp. The format can also be adjusted, defaulting to the standard WooCommerce date format.
Fix - WPML - Workflow email previews now only show products in the language of the current workflow

New - Added support for WooCommerce 3.7

* Fix - Error when loading the Emogrifier library in some environments
* Tweak - Added two requested filter hooks `automatewoo/cart_item/get_quantity` and `automatewoo/cart/get_shipping_total_html`
