JAX shipped native top_k alignment with NumPy 2.6.0 while simultaneously landing full OneAPI CI infrastructure for Intel GPU testing across the entire stack.

JAX landed two major capability expansions this cycle. First, `jax.numpy.top_k` now implements parity with NumPy v2.6.0 [2], tested against both the NumPy nightly and fallback baselines to ensure compatibility across versions. Simultaneously, OneAPI CI infrastructure hit the JAX tree [3], adding automated GPU detection, parallelization scripts, and the full test harness for Intel GPU backends. This represents the completion of GPU vendor diversity in JAX's continuous integration pipeline.

On the performance front, JAX added native support for lane dimension argmax/argmin operations with bf16 inputs on Mosaic TPU [1], enabling efficient 16-bit instruction paths via `lax.argmax/argmin` with `index_type=int16`. The team also fixed a reduce_max/reduce_min operand passthrough issue and added upstream rules for div [4] to resolve JVP call chains.

Down the stack, google-cloud-python addressed critical operational issues. A debug print statement was leaking to stdout in every BigQuery RangeQueryParameter construction [7], now removed. The team also standardized x-goog-api-client header handling to prevent duplication across the auth/core/user layers [6], reducing backend compatibility friction. Pandas-GBQ version detection gained a capability helper for safe delegation and telemetry [5], handling missing or corrupted installations gracefully.
