Enhancement: Cart subtotal now supports multiple currency thresholds
A cart subtotal condition can now set an exact amount for each of your store's currencies.

What's new. Until now, a cart value condition held one amount that was compared with the cart in whatever currency the shopper paid in. A store pricing in Australian dollars with an A$380 threshold would hide the offer from a US shopper spending US$273 (about A$420). Choose Add another currency to pin an exact amount for each currency you sell in, for example A$380 and US$250.
Where it applies. Display rules and upsell discount conditions. Currencies without their own amount work as they did before.
Your existing conditions are unchanged. No action is needed on your end.
