Changelog

Rate display fixes and compatibility refresh.

• Fixed: the live rate reported as unavailable in three places even when the API answered normally. The gateway settings page showed "Could not fetch rate.", System Status listed no rate, and block checkout received no rate at all.
• Changed: the rate now displays to 2 decimal places (1 UNC = AUD 1.00), matching every other amount shown by the plugin.
• Compatibility: verified against WordPress 7.0 and WooCommerce 10.9, including block checkout, classic checkout, and HPOS both enabled and disabled.
• Webhook signature handling verified: valid signatures accepted, and forged, tampered, replayed, or unsigned requests rejected.

API field alignment.

• Changed: amount fields in payment and refund requests and in the webhook payload were renamed for consistency with the UniPay API. Amounts are expressed in AUD.
• Requires the current UniPay API. Live since June 2026.
