Jan 1, 2025

January 2025: Delivered impactful features and stability improvements across datarobot/airflow-provider-datarobot and datarobot/datarobot-user-models. Highlights include optimization of the Astro-dev build to avoid copying example DAGs by default; modernization of code quality tooling with pre-commit, Ruff, and mypy in CI; automation for operator generation from Python docstrings via a new Makefile target; OpenAI integration stabilized by pinning httpx to prevent breakage in Python 3.11 GenAI and GPU environments; and a DRUM upgrade to 1.16.4 enabling Python 3.12 support with corresponding metadata and pipeline checks. These efforts reduce build noise and risk, improve maintainability, enable newer runtimes, and set the stage for continued automation.
