June 2025 monthly summary for onnx/onnx: Delivered cross-platform Python 3.14-dev support for Linux wheels and updated CI to build/test against 3.14-dev on macOS/Windows, including artifact handling. Stabilized Windows ARM64 builds by aligning Python versions (3.13.x). Refined CI workflows with naming cleanup for better UX and maintainability. Updated build/dependency pipelines (requirements-release_build) and Model Zoo docs workflows to align with deprecations and ensure correct docs builds. Implemented CI cost optimization by switching weekly Model Zoo runner to Linux, reducing macOS test runs, and trimming macOS Python variants, weekly pixi_build runs. Fixed documentation typos and release management references to prevent release schedule mismatches. Cleaned up entrypoint.sh to remove unused dependencies and streamline builds.

May 2025 (2025-05) monthly summary for repo onnx/onnx focusing on release stability, reproducibility, testing alignment, and governance enhancements. The efforts delivered deterministic and reproducible builds, improved dependency handling, and clearer release planning, enabling more reliable packaging and faster downstream integration. Key outcomes include stabilized release/workflow pipelines, alignment of tests with current dependencies and numpy versions, and expanded governance documentation for planning and deprecation policies. These changes reduce release risk, improve maintainability, and enhance transparency for contributors and users.

April 2025 focused on strengthening build reliability, cross-platform coverage, and release automation for ONNX and ONNX-MLIR. Highlights include integrating Free-Threading into Linux wheel builds, enabling both release and preview builds in the release workflow, adding a publishing workflow to Test PyPI, expanding cross-architecture releases with native ARM64 Windows builds and Linux ARM64 updates (including 3.13t), and CI/release process improvements such as cleaning up CI configurations, updating versioning to 1.19, and refreshing Onnx release documentation. These efforts deliver faster, more reliable releases and broader platform support for downstream customers while reducing maintenance risk of the CI pipeline.

March 2025: Strengthened release reliability, dependency hygiene, and cross‑platform freethreading support for onnx/onnx.
