JAX removes deprecated pipelining APIs and patches mpmath warnings as the Python client libraries ship multimodal audio support and a critical Spanner identifier injection fix.

JAX's experimental custom pipelining APIs are gone [1], clearing out code that never shipped publicly and would have required substantial work to land. The same release kills mpmath 1.4+ deprecation warnings that were breaking pytest runs [2] by triggering module-level attribute lookups. On the random side, JAX now ships a faster approximate Poisson sampler with derivative support, though the derivative estimates carry bias since the underlying distribution isn't truly continuous [3]. Meanwhile, python-genai landed two major feature waves: enterprise mode now accepts API keys alongside project and location parameters [4], and GenerateContentConfig now supports audio transcription configuration with a new Part.audio_transcription field [5]. The critical story is google-cloud-python, where Spanner's escape_name function was allowing identifier injection through unescaped backticks (CWE-89) [6], now patched to double-escape embedded backticks. The same monorepo bumped grpcio to 1.59.0 and dropped Python 3.9 support [7], consolidating versions across the dependency tree. Generator improvements switched unit test imports from recursive to flat references, eliminating transitive _pb2 imports and deleting legacy post-processing scripts [8], though the removal had to be partially reverted pending a generator bump [9].

Action items

→ Upgrade google-cloud-spanner immediately to patch identifier injection in escape_name googleapis/google-cloud-python [immediate]
→ Plan grpcio 1.59.0 upgrade and Python 3.10+ migration for google-cloud-python googleapis/google-cloud-python [plan]
→ Update JAX to latest for mpmath 1.4+ compatibility and Poisson sampler google/jax [plan]
→ Monitor python-genai enterprise auth and audio transcription APIs for stability googleapis/python-genai [monitor]
