- Updated plugin URI for better branding consistency. - Added environment checks to ensure WooCommerce is installed and meets version requirements. - Improved AJAX handling for shipment creation and tracking updates, including enhanced error messages. - Streamlined order management with new custom order statuses and improved logging for better tracking. - Removed deprecated API test page and updated admin interface for clarity. - Enhanced localization by ensuring all translatable strings use esc_html functions for security. These changes improve the robustness, usability, and maintainability of the CZL Express plugin.
