Smart Transaction Systems Gift Cards for WooCommerce

1.0

• Initial public release on WordPress.org.
• Gift cards now integrate with WooCommerce’s native coupon system; redemption works on Classic and Block Checkout without a custom form.
• HPOS (custom order tables) compatibility declared.
• Security hardening: nonce + capability checks on admin save paths, output escaping across display surfaces, cryptographically strong gift-card number generation, XML-escaped gateway requests.
• Gateway HTTP calls migrated from raw cURL to the WordPress HTTP API with TLS verification enabled.
• No gateway requests are made until merchant credentials are configured.
• PHP 8.x compatibility fixes.
