During March 2025, Petr Hubík enhanced PHP 8.4 readiness across the microsoftgraph/msgraph-sdk-php and msgraph-beta-sdk-php repositories. He updated CI/CD workflows to include PHP 8.4 in the validation matrix and refined the GraphRequestAdapter to support a nullable httpClient parameter, ensuring compatibility with the upcoming PHP release while maintaining backward compatibility. Petr’s approach focused on minimizing migration risk and preserving consistent adapter behavior across repositories. By leveraging PHP, YAML, and CI/CD best practices, he delivered targeted updates that improved test coverage and streamlined the upgrade path, demonstrating a thoughtful balance between forward compatibility and stable, maintainable code.
