{func}jax.lax.eigh now accepts an optional sort_eigenvalues argument
that allows users to opt out of eigenvalue sorting on TPU.
Deprecations
Non-array arguments to functions in {mod}jax.lax.linalg are now marked
keyword-only. As a backward-compatibility step passing keyword-only
arguments positionally yields a warning, but in a future JAX release passing
keyword-only arguments positionally will fail.
However, most users should prefer to use {mod}jax.numpy.linalg instead.
{func}jax.scipy.linalg.polar_unitary, which was a JAX extension to the
scipy API, is deprecated. Use {func}jax.scipy.linalg.polar instead.
{func}jax.scipy.linalg.qr now returns a length-1 tuple rather than the raw array when mode='r', in order to match the behavior of scipy.linalg.qr ({jax-issue}#10452)
{func}jax.numpy.take_along_axis now takes an optional mode parameter that specifies the behavior of out-of-bounds indexing. By default, invalid values (e.g., NaN) will be returned for out-of-bounds indices. In previous versions of JAX, invalid indices were clamped into range. The previous behavior can be restored by passing mode="clip".
{func}jax.numpy.take now defaults to mode="fill", which returns invalid values (e.g., NaN) for out-of-bounds indices.
Scatter operations, such as x.at[...].set(...), now have "drop" semantics. This has no effect on the scatter operation itself, but it means that when differentiated the gradient of a scatter will yield zero cotangents for out-of-bounds indices. Previously out-of-bounds indices were clamped into range for the gradient, which was not mathematically correct.
{func}jax.numpy.take_along_axis now raises a TypeError if its indices are not of an integer type, matching the behavior of
{func}numpy.take_along_axis. Previously non-integer indices were silently cast to integers.
{func}jax.numpy.ravel_multi_index now raises a TypeError if its dims argument is not of an integer type, matching the behavior of {func}numpy.ravel_multi_index. Previously non-integer dims was silently cast to integers.
{func}jax.numpy.split now raises a TypeError if its axis argument is not of an integer type, matching the behavior of {func}numpy.split. Previously non-integer axis was silently cast to integers.
{func}jax.numpy.indices now raises a TypeError if its dimensions are not of an integer type, matching the behavior of {func}numpy.indices. Previously non-integer dimensions were silently cast to integers.
{func}jax.numpy.diag now raises a TypeError if its k argument is not of an integer type, matching the behavior of {func}numpy.diag. Previously non-integer k was silently cast to integers.
Added {func}jax.random.orthogonal.
Deprecations
Many functions and objects available in {mod}jax.test_util are now deprecated and will raise a warning on import. This includes cases_from_list, check_close, check_eq, device_under_test, format_shape_dtype_string, rand_uniform, skip_on_devices, with_config, xla_bridge, and _default_tolerance ({jax-issue}#10389). These, along with previously-deprecated JaxTestCase, JaxTestLoader, and BufferDonationTestCase, will be removed in a future JAX release. Most of these utilites can be replaced by calls to standard python & numpy testing utilities found in e.g. {mod}unittest, {mod}absl.testing, {mod}numpy.testing, etc. JAX-specific functionality such as device checking can be replaced through the use of public APIs such as {func}jax.devices. Many of the deprecated utilities will still exist in {mod}jax._src.test_util, but these are not public APIs and as such may be changed or removed without notice in future releases.
Fixed a performance problem if the indices passed to jax.numpy.take_along_axis were broadcasted (#10281).
jax.scipy.special.expit and jax.scipy.special.logit now require their arguments to be scalars or JAX arrays. They also now promote integer arguments to floating point.
The DeviceArray.tile() method is deprecated, because numpy arrays do not have a tile() method. As a replacement for this, use jax.numpy.tile (#10266).
