JAX pulled back from making the `fun` parameter positional-only in custom_gradient, preserving backward compatibility just before release.

The custom_gradient function was about to lose flexibility in how developers pass the `fun` argument [1], a change that would have broken existing code across the ecosystem. JAX maintainers caught this in review and reverted course [2], keeping the parameter keyword-compatible. In parallel, the team updated XLA dependencies to pull in the latest compiler improvements [3], keeping the ML stack current without collision. Two commits, one PR: minimal churn, maximum fidelity. This is exactly how you handle API stability at scale.
