* Start translations for Italian. PR [#1557](https://github.com/tiangolo/fastapi/pull/1557) by [@csr](https://github.com/csr).

## 0.56.0

* Add support for ASGI `root_path`:
    * Use `root_path` internally for mounted applications, so that OpenAPI and the docs UI works automatically without extra configurations and parameters.

        `LookupTable`.
    *   Fix bug where `vectorized_map` failed on inputs with unknown static
        shape.
    *   Add preliminary support for sparse CSR matrices.
    *   Tensor equality with `None` now behaves as expected.
    *   Make calls to `tf.function(f)()`, `tf.function(f).get_concrete_function`
        and `tf.function(f).get_initialization_function` thread-safe.
