## Historial de cambios

Versión | Descripción
--- | ---
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.
