Pydantic is moving fast on Python 3.15 support while the FastAPI ecosystem standardizes on a new release notes workflow.

Pydantic shipped three substantial PRs overnight that signal serious forward momentum. Viicos added initial Python 3.15 CI support [1], refactored model namespace inspection to handle annotation evaluation more cleanly [2], and prepped v2.14.0b1 for release [3]. The 3.15 work surfaces real stdlib breakage around base64 handling that will need addressing before the final Python release. On the release front, PyO3 bumped to 0.29.2 [4], keeping the native layer current. Meanwhile, both FastAPI and SQLModel removed their legacy Latest Changes workflows now that the GitHub App handles automation [5] [6], a quiet but necessary cleanup that unblocks faster release cycles across the ecosystem. Release notes got auto-updated to reflect the changes [7] [8].
