JAX drops NumPy 2.1 and stale version gates
By RepoJournal · Filed · About Google · Composed from the cited sources · methodology
JAX's build floor moves up while its numerical tests start measuring true ULP error instead of bit distance, and the Firestore Python SDK grows BSON timestamp and binary types.
Drop support for NumPy 2.1. google/jax
Support for NumPy 2.1 is gone, and the requirements lock files were regenerated alongside it. If your environment still pins NumPy 2.1, installing current jax now fails at resolve time rather than at runtime, so bump the pin before upgrading.
Measure real ULP errors in `numerics` tests (`elementary_test` and `special_test`). google/jax
The numerics test helper in `numerics_test_util` now measures continuous floating-point ULP error instead of integer bit-distance between rounded output and rounded reference, computing a high-precision reference (float64 for narrower types, mpmath for float64) and measuring error against `ulp(ref)`. It also changes the default ULP error bound, so `elementary_test` and `special_test` assert aga...
Consolidate elementary and special function accuracy documentation. google/jax
A new docs/accuracy.md collects maximum error bounds for elementary and special functions across CPU, GPU, and TPU for bfloat16, float16, float32, and float64, with cross-references added from docstrings throughout jax.numpy, jax.lax, and jax.scipy.special. Precision expectations that previously lived in scattered test tolerances are now written down per architecture and dtype.
Remove version checks that are now always false: google/jax
The dead branches came out: checks for jaxlib minimum version 0.11.2, ifrt_version 69, jaxlib_extension_version 495, and libtpu 0.0.48 are always false and were deleted. Anyone building jaxlib or libtpu from source should treat those as the effective floors.
feat(firestore): add BSONTimestamp support googleapis/google-cloud-python
Firestore gains a `BSONTimestamp` container class in `google.cloud.firestore_v1.bson`, wrapping the 32-bit unsigned `seconds` and `increment` fields of an internal BSON operation log timestamp with spec-compliant unsigned conversion, alongside BSONBinary support for subtyped payloads such as UUIDs and MD5 hashes. The long tail was quiet: two `chore: Misc updates` commits in python-genai, a blac...
