* ✨ Serialize JSON response with Pydantic (in Rust), when there's a Pydantic return type or response model. PR [#14962](https://github.com/fastapi/fastapi/pull/14962) by [@tiangolo](https://github.com/tiangolo).
    * This results in 2x (or more) performance increase for JSON responses.
    * New docs: [Custom Response - JSON Performance](https://fastapi.tiangolo.com/advanced/custom-response/#json-performance).

## 0.129.2 (2026-02-21)

### Internal

*   Add in-memory caching to the Dataset API.
*   Set default end_of_sequence variable in datasets iterators to false.
*   [Performance] Increase performance of `tf.layers.conv2d` when setting
    use_bias=True by 2x by using nn.bias_add.
*   Update iOS examples to use CocoaPods, and moved to tensorflow/examples/ios.
*   Adds a family= attribute in `tf.summary` ops to allow controlling the tab
