JAX's PjRt layer now accepts SDY target versions during serialization, giving you fine-grained control over compatibility across versions.

The big shift on the JAX desk: SDY dialect target versioning is live [1]. Serialize() and SerializeUsingVersionedStablehlo() now accept an explicit SDY target version parameter, with GetDefaultSdyVersion() providing sensible defaults (following the same 12-week deprecation window as StableHlo). This matters because it lets you version-lock your compiled kernels independent of your JAX runtime. Meanwhile, JAX added the Faddeeva function (wofz) and extended erfcx to handle complex inputs [2], rounding out the scipy.special family. Shape polymorphism now has partial support for ragged_dot [3], though modes 1 and 2 still bail on dynamic group sizes (error messages now in place). The OneAPI GPU plugin skeleton landed [4], setting up Intel SYCL infrastructure with no kernel implementations yet, so don't expect GPU compute from this one. On the Google Cloud front, google-cloud-logging is cutting Python 3.7, 3.8, and 3.9 support [5], consolidating on 3.10+ and modernizing dependency chains. The gapic-generator shipped two releases [6][7] fixing coverage pragmas and URL routing in setup.py. Python-genai expanded computer_use field support for Vertex [8]. One test suite fix resolved a protobuf unpacking issue in BigTable admin tests [9].
