This release also includes a number of updates targeting the WooCommerce PayPal gateway integration:

Enhanced Country Code Handling for PayPal Standard #61741
This update improves PayPal Standard’s country code processing by integrating the league/iso3166 composer package. The enhancement automatically identifies and converts three-letter ISO country codes to the two-letter format required by PayPal, preventing transaction errors caused by country code format mismatches. Additional minor fixes ensure more reliable PayPal integration across different country configurations.

Consistent Two-Letter Country Code Format #61691
Country codes sent to PayPal when using PayPal Standard are now consistently formatted as two-letter codes, matching PayPal’s API requirements. This standardization prevents country code-related errors during the checkout process.

Standardized Locale Code Format for PayPal Orders #61688
PayPal Standard now correctly formats locale codes by limiting them to two characters when creating orders. This fix ensures that language and region codes sent to PayPal comply with their API requirements, preventing potential order creation failures due to improperly formatted locale data.

Resolved PayPal Shipping Callback Configuration Errors #61689
This fix eliminates the SHIPPING_CALLBACK_CONFIG_NOT_SUPPORTED errors that were occurring with PayPal Standard transactions. The update ensures shipping callback configurations are properly structured and compatible with PayPal’s current API specifications, providing a smoother checkout experience.

Refined Address Field Requirements for PayPal Orders V2 API #61724
Address validation for PayPal transactions now accurately reflects PayPal’s official address requirements table for the Orders V2 API. This improvement ensures that city and postal code field requirements are correctly defined based on the customer’s country, reducing address-related transaction failures and improving international checkout compatibility.

Improved Handling of Negative Amount Line Items #61719
PayPal Standard now correctly processes order items with negative amounts, such as discounts or fee adjustments. This fix ensures accurate order total calculations and prevents transaction failures when orders include negative line item values.

Unified Order Total Calculation for PayPal Standard #61692
Order item total calculations for PayPal Standard purchases are now unified, ensuring consistent and accurate amounts are sent to PayPal. This improvement prevents discrepancies between WooCommerce and PayPal totals that could cause transaction failures.
