JAX shipped two new PRNG implementations with larger key and counter spaces, giving you better statistical properties for large-scale sampling - right as the Google Cloud Python suite drops Python 3.7 through 3.9 entirely.

The JAX team added philox4x32 and threefry4x32 PRNG implementations [1] [2], both offering 128-bit counter spaces compared to their smaller predecessors. Philox4x32 uses 64-bit keys with operations that accelerators can lower more efficiently, while threefry4x32 pushes to 128-bit keys for contexts generating many samples. These hit `jax.random.key` directly with the `impl` parameter, so you can switch without changing calling code. On the GPU side, XLA folded autotuning logic into native and block-level emitters [3], tightening compilation and reducing redundant kernel selection. Meanwhile, Google Cloud Python is officially ending support for Python 3.7, 3.8, and 3.9 [4] [5] [8], updating lower bounds across Storage and Spanner with 3.10 as the new floor. The Storage team also optimized zonal system tests for concurrency and speed [6], while Spanner fixed idempotent database restore retries by catching AlreadyExists and validating backup state [7]. Python-genai added Gemini 3.5 Flash to model options [9], ready for immediate use.
