* 🔧 Add Pydantic 2 trove classifier. PR [#13199](https://github.com/fastapi/fastapi/pull/13199) by [@johnthagen](https://github.com/johnthagen).

*   `Estimator.export_savedmodel()` now includes all valid serving signatures
    that can be constructed from the Serving Input Receiver and all available
    ExportOutputs. For instance, a classifier may provide regression- and
    prediction-flavored outputs, in addition to the classification-flavored one.
    Building signatures from these allows TF Serving to honor requests using the
