Changelog

Version Description
PECL mongodb 2.0.0 Return types previously declared as tentative are now enforced.
PECL mongodb 1.15.0 Return types for methods are declared as tentative on PHP 8.0 and newer, triggering deprecation notices in code that implements this interface without declaring the appropriate return types. The #[ReturnTypeWillChange] attribute can be added to silence the deprecation notice.
