- **changed** — The semi-private type jax._src.literals.TypedNdArray is now a subclass of np.ndarray, rather than a duck type of it
- **changed** — jax.numpy.arange with step specified no longer generates the array on host, resulting in more efficient code but potentially less precise outputs for narrow-width floats like bfloat16

##### JAX 0.9.2 (March 2, 2026)

* Changes:
  * The semi-private type `jax._src.literals.TypedNdArray` is now a subclass of
    `np.ndarray`, rather than a duck type of it.
  * `jax.numpy.arange` with `step` specified no longer generates the array
    on host. The benefit is more efficient code, though this can lead to less
    precise outputs for narrow-width floats (e.g. bfloat16). To recover the
    previous behavior in this case, use `jnp.array(np.arange(...))`.
