JAX Pallas now has native convolution operators for TPU, part one of a three-part overhaul that unlocks spatial N-D convolutions directly in the MLIR Mosaic dialect.

The headline feature is Pallas convolution support [1], which brings pltpu.conv and lax.conv_general_dilated to TPU inference and training without falling back to slower decomposition paths. This lands Part 1 of the work: the TPU_ConvOp dialect definition, verification, Python bindings, and canonicalization into window slicing and matmul lowering. Dilations and negative padding follow in Part 2. Separately, Peter Hawkins lifted the Python 3.15 version constraint on libtpu [2] now that libtpu 0.0.46 ships with 3.15 wheels, clearing the path for JAX on the latest Python. JAX also modernized its type hints, replacing typing.Union and typing.Optional with PEP 604 syntax [3]. Over on the Genai side, python-genai added data retention controls to ToolParallelAiSearch alongside step_count for reinforcement tuning and BidiGenerateContentSetup [4], while AudioTranscriptionConfig now exposes VERBATIM and SMART modes [5]. On the cloud-python front, documentation is now published to https://cloud.google.com/python/docs/reference [6] under Client libraries help, and a packaging bug in google-cloud-audit-log that was installing unintended top-level docs was fixed [7].
