New features

• JAX now ships Python 3.14 and 3.14t wheels.
• JAX now ships Python 3.13t and 3.14t wheels on Mac. Previously we only offered free-threading builds on Linux.

Changes

• Exposed jax.set_mesh which acts as a global setter and a context manager. Removed jax.sharding.use_mesh in favor of jax.set_mesh.
• JAX is now built using CUDA 12.9. All versions of CUDA 12.1 or newer remain supported.
• jax.lax.dot now implements the general dot product via the optional dimension_numbers argument.

Deprecations:

• jax.lax.zeros_like_array is deprecated. Please use jax.numpy.zeros_like instead.
• Attempting to import jax.experimental.host_callback now results in a DeprecationWarning, and will result in an ImportError starting in JAX v0.8.0. Its APIs have raised NotImplementedError since JAX version 0.4.35.
• In jax.lax.dot, passing the precision and preferred_element_type arguments by position is deprecated. Pass them by explicit keyword instead.
• Several dozen internal APIs have been deprecated from jax.interpreters.ad, jax.interpreters.batching, and jax.interpreters.partial_eval; they are used rarely if ever outside JAX itself, and most are deprecated without any public replacement.
