- Lower and upper case feature flag values are now allowed, but the name still has to match. ([#121441](https://github.com/kubernetes/kubernetes/pull/121441), [@soltysh](https://github.com/soltysh))
- Makefile and scripts now respect `GOTOOLCHAIN` and otherwise ensure `./.go-version` is used. ([#120279](https://github.com/kubernetes/kubernetes/pull/120279), [@BenTheElder](https://github.com/BenTheElder))

*   `tf.lite`:

    *   Rename fields `SignatureDef` table in schema to maximize the parity with
        TF SavedModel's Signature concept.
    *   Deprecate Makefile builds. Makefile users need to migrate their builds
        to CMake or Bazel. Please refer to the
        [Build TensorFlow Lite with CMake](https://www.tensorflow.org/lite/guide/build_cmake)
