- Updated system requirements in the README to reflect compatibility with WordPress 6.0+ and PHP 7.4+. - Revised usage steps for better clarity on plugin installation and configuration. - Improved order management features, including AJAX handling for shipment creation and tracking updates. - Added new custom order statuses (In Transit, Delivered) for better order tracking. - Enhanced error handling and logging during shipment creation and tracking updates. - Introduced chargeable weight calculation for shipping rates based on product dimensions and weight. These changes enhance the overall performance and usability of the CZL Express plugin.
