GOOGLE DROPS PYTHON 3.9 ACROSS THE STACK WHILE JAX HARDENS CI

By RepoJournal · Filed · About Google

Google-auth, testutils, runtimeconfig, and bigquery-magics are all moving to Python 3.10 as minimum, signaling a coordinated platform shift across cloud libraries.

The cloud-python desk executed a synchronized version floor lift overnight [1][2][3][4], dropping Python 3.9 support across four major packages and establishing 3.10 as the new baseline. This isn't a casual cleanup—it's a coordinated move that affects every downstream service using google-auth, the foundation of GCP authentication. Meanwhile, the JAX team hardened their CI pipeline by adding zizmor security scanning to every push and PR [5], a proactive defense against supply-chain risks. On the build front, JAX also prepped for the Bzlmod migration [9] by introducing --override_module flags alongside the deprecated --override_repository, ensuring smooth transition when the default flips. The python-genai desk shipped polymorphic response_format changes [6][7] and added interaction steps support [8], modernizing the API surface for AI applications.
