`True`,`tf.data` will now automatically add a `prefetch` transformation
        to datasets that end in synchronous transformations. This enables data
        generation to be overlapped with data consumption. This may cause a
        small increase in memory usage due to buffering. To enable this
        behavior, set `inject_prefetch=True` in
        `tf.data.experimental.OptimizationOptions`.

* Improved **correctness** in corner cases.
* **Safer** types.
* Better **performance** and **less energy** consumption.
* Better **extensibility**.
* etc.

...all this while keeping the **same Python API**. In most of the cases, for simple models, you can simply upgrade the Pydantic version and get all the benefits. 🚀
