Compatibility And Release History
The source declares PHP 8.0+. Use the supported PHP version for your exact WHMCS installation and confirm package compatibility with HERZA. A complete historical changelog and broad compatibility test matrix were not established during this documentation review, so earlier release changes are not inferred.
