 ### Changed
 - Added support for version v2.1-25.2.00.00 of the DocuSign ESignature API.
 - Updated the SDK release version.
+- Modernized constructor classes in Api, Client and Model files (including Configuration.php file) by adding `?array $data = null` to address deprecated warnings in PHP.
+- Added return types (`bool`, `mixed`, and `void`) to several functions in model files to improve type safety and compatibility with modern PHP versions.
