Added jax.P which is an alias for jax.sharding.PartitionSpec.
Added jax.tree.reduce_associative.
Breaking changes:
JAX is migrating from GSPMD to Shardy by default. See the
migration guide
for more information.
JAX autodiff is switching to using direct linearization by default (instead of
implementing linearization via JVP and partial eval).
See migration guide
for more information.
jax.stages.OutInfo has been replaced with .
jax.ShapeDtypeStruct
jax.jit now requires fun to be passed by position, and additional
arguments to be passed by keyword. Doing otherwise will result in an error
starting in v0.7.x. This raised a DeprecationWarning in v0.6.x.
The minimum Python version is now 3.11. 3.11 will remain the minimum
supported version until July 2026.
Layout API renames:
Layout, .layout, .input_layouts and .output_layouts have been
renamed to Format, .format, .input_formats and .output_formats
DeviceLocalLayout, .device_local_layout have been renamed to Layout
and .layout
jax.experimental.shard module has been deleted and all the APIs have been
moved to the jax.sharding endpoint. So use jax.sharding.reshard,
jax.sharding.auto_axes and jax.sharding.explicit_axes instead of their
experimental endpoints.
lax.infeed and lax.outfeed were removed, after being deprecated in
JAX 0.6. The transfer_to_infeed and transfer_from_outfeed methods were
also removed the Device objects.
The jax.extend.core.primitives.pjit_p primitive has been renamed to
jit_p, and its name attribute has changed from "pjit" to "jit".
This affects the string representations of jaxprs. The same primitive is no
longer exported from the jax.experimental.pjit module.
The (undocumented) function jax.extend.backend.add_clear_backends_callback
has been removed. Users should use jax.extend.backend.register_backend_cache
instead.
Deprecations:
{obj}jax.dlpack.SUPPORTED_DTYPES is deprecated; please use the new
jax.dlpack.is_supported_dtype function.
jax.scipy.special.sph_harm has been deprecated following a similar
deprecation in SciPy; use jax.scipy.special.sph_harm_y instead.
From {mod}jax.interpreters.xla, the previously deprecated symbols
abstractify and pytype_aval_mappings have been removed.
jax.interpreters.xla.canonicalize_dtype is deprecated. For
canonicalizing dtypes, prefer jax.dtypes.canonicalize_dtype.
For checking whether an object is a valid jax input, prefer
jax.core.valid_jaxtype.
From {mod}jax.core, the previously deprecated symbols AxisName,
ConcretizationTypeError, axis_frame, call_p, closed_call_p,
get_type, trace_state_clean, typematch, and typecheck have been
removed.
From {mod}jax.lib.xla_client, the previously deprecated symbols
DeviceAssignment, get_topology_for_devices, and mlir_api_version
have been removed.
jax.extend.ffi was removed after being deprecated in v0.5.0.
Use {mod}jax.ffi instead.
jax.lib.xla_bridge.get_compile_options is deprecated, and replaced by
jax.extend.backend.get_compile_options.
