### Feature

- Add architecture to the kernel version column in the `kubectl get node -owide` output. ([#132402](https://github.com/kubernetes/kubernetes/pull/132402), [@astraw99](https://github.com/astraw99)) [SIG CLI]

    operations such as categorical feature encoding, text vectorization, data
    normalization, and data discretization (binning). The newly added layers
    provide a replacement for the legacy feature column API, and support
    composite tensor inputs.
*   Added **categorical data** processing layers:
    *   `IntegerLookup` & `StringLookup`: build an index of categorical feature
        values

The sequence of execution before FastAPI 0.106.0 was like this diagram:

Time flows from top to bottom. And each column is one of the parts interacting or executing code.
