- **removed** — jax.dlpack.from_dlpack no longer accepts a DLPack capsule and must be called with an array implementing __dlpack__ and __dlpack_device__
- **changed** — Minimum supported NumPy version is now 2.0
- **changed** — Minimum supported SciPy version is now 1.13
- **changed** — JAX now represents constants in its internal jaxpr representation as a LiteralArray, a private JAX type that duck types as a numpy.ndarray
- **fixed** — arr.view(dtype=None) now returns the array unchanged, matching NumPy's semantics
- **fixed** — jax.random.randint now produces a less-biased distribution for 8-bit and 16-bit integer types
- **deprecated** — The parameters enable_xla and native_serialization for jax2tf.convert are deprecated and will be removed in a future version
- **deprecated** — Setting the config state jax_pmap_no_rank_reduction to False is deprecated

* Breaking changes:

  * `jax.dlpack.from_dlpack` no longer accepts a DLPack capsule. This
    behavior was deprecated and is now removed. The function must be called
    with an array implementing `__dlpack__` and `__dlpack_device__`.

* Changes
  * The minimum supported NumPy version is now 2.0. Since SciPy 1.13 is required
    for NumPy 2.0 support, the minimum supported SciPy version is now 1.13.

  * JAX now represents constants in its internal jaxpr representation as a
    `LiteralArray`, which is a private JAX type that duck types as a
    `numpy.ndarray`. This type may be exposed to users via `custom_jvp` rules,
    for example, and may break code that uses `isinstance(x, np.ndarray)`. If
    this breaks your code, you may convert these arrays to classic NumPy arrays
    using `np.asarray(x)`.

* Bug fixes
  * `arr.view(dtype=None)` now returns the array unchanged, matching NumPy's
    semantics. Previously it returned the array with a float dtype.
  * `jax.random.randint` now produces a less-biased distribution for 8-bit and
    16-bit integer types ({jax-issue}`#27742`). To restore the previous biased
    behavior, you may temporarily set the `jax_safer_randint` configuration to
    `False`, but note this is a temporary config that will be removed in a
    future release.

* Deprecations:
  * The parameters `enable_xla` and `native_serialization` for `jax2tf.convert`
    are deprecated and will be removed in a future version of JAX. These were
    used for jax2tf with non-native serialization, which has been now removed.
  * Setting the config state `jax_pmap_no_rank_reduction` to `False` is
    deprecated. By default, `jax_pmap_no_rank_reduction` will be set to `True`
    and `jax.pmap` shards will not have their rank reduced, keeping the same
    rank as their enclosing array.
