Release 1.4.0

🚀 Highlights

✨ Features

• Core: CSV sample store now supports specifying an actuator for more flexible data ingestion.
• Ray Tune: Introduced a difference stopper to halt sampling when its probable that the difference in two metrics is above or below a threshold

🐛 Fixes

• Core: Record relationships with nested operations when they are interrupted.
• Ordered Pip: pip_install_options now correctly propagates across all phases of an ordered install
• Modules: Correct type annotations for closures.

⚡ Performance

• Adopted NumPy’s new RNG APIs for faster and more consistent randomness.

🧰 Tooling & CI

• Broad dependency updates, pre-commit hook refresh, and stricter linters (ANN, Bandit).
• Test coverage reporting added.

📝 Docs

• Changelog refresh and HYBRID_SHARD documentation improvements.

---

🧪 sfttrainer

• Added support for fms-hf-tuning v3.1.0 and fixed related issues.
• Packaging streamlined: only the ado-sfttrainer wheel is propagated.
• Documentation updated for HYBRID_SHARD behavior.
• General code hygiene: type annotations & small readability tweaks.

🚄 vllm_performance

• New GuideLLM experiments to expand benchmarking coverage.
• Kubernetes namespace now RFC1123-compliant.
• Bumped requirement to vLLM ≥ 0.12.0 and refreshed dependencies.
• Hardening & cleanup: safer command invocation (no shell=True) and parameter upgrade-path removal.

⚙️ autoconf

• Added comprehensive type annotations for better IDE support and static analysis.
