* Breaking Changes * Breaking Changes
* This release lands "stackless", an internal change to JAX's tracing
machinery. We made trace dispatch purely a function of context rather than a
function of both context and data. This let us delete a lot of machinery for
managing data-dependent tracing: levels, sublevels, `post_process_call`,
`new_base_main`, `custom_bind`, and so on. The change should only affect
users that use JAX internals.
If you do use JAX internals then you may need to
update your code (see
https://github.com/jax-ml/jax/commit/c36e1f7c1ad4782060cbc8e8c596d85dfb83986f
for clues about how to do this). There might also be version skew
issues with JAX libraries that do this. If you find this change breaks your
non-JAX-internals-using code then try the
`config.jax_data_dependent_tracing_fallback` flag as a workaround, and if
you need help updating your code then please file a bug.
