Bien que le système hiérarchique d’injection de dépendances soit très simple à définir et à utiliser, il reste très puissant.

            <p>In addition to the traditional activation mechanisms (JDK version, OS properties,
            file existence, etc.), Maven now supports a powerful condition-based activation
            through the {@code condition} field. This new mechanism allows for more flexible
            and expressive profile activation rules.</p>

TensorFlow 2.0 focuses on **simplicity** and **ease of use**, featuring updates
like:

*   Easy model building with Keras and eager execution.
*   Robust model deployment in production on any platform.
*   Powerful experimentation for research.
*   API simplification by reducing duplication and removing deprecated
    endpoints.

**Note**: You probably don't need `contextvars`, and you should probably avoid using them. But they are powerful and useful in some advanced scenarios, for example, migrating from code that used Flask's `g` semi-global variable.
