April 2026: This month focused on reliability enhancements in the inference pipeline and security/compatibility upgrades for ONNX in the onnx/onnx-mlir repository. Delivered targeted fixes to reduce runtime-related risks, preserve test output integrity, and strengthen security posture, enabling safer deployments and more deterministic testing across environments.

March 2026 (2026-03) focused on improving deployment reliability and build stability for onnx/onnx-mlir. Key deliverables include cross-architecture manifest accuracy by removing ppc64le from the multi-arch manifest, and stabilization of MLIR caching on macOS when using protobuf@33 by ensuring the cache key has no spaces and using the correct protoc version. These changes reduce deployment drift, prevent failures due to missing images, and improve developer productivity by faster, more reliable builds across environments.

February 2026 monthly summary for onnx/onnx-mlir: Delivered Platform Base Image Upgrade to improve compatibility and performance across development and runtime environments. This work standardizes base images, reduces environment discrepancies, and enables smoother CI and onboarding.

Monthly summary for 2026-01 focused on stabilizing Docker-based builds for onnx/onnx-mlir and ensuring protobuf compatibility. Delivered a Dockerfile fix to let protobuf automatically download and build abseil-cpp, with an explicit C++17 standard requirement to satisfy protobuf's C++17 needs. This reduced manual dependency handling and built a more reproducible CI that aligns with protobuf and clang++ expectations.

Monthly summary for 2025-10 focusing on onnx/onnx-mlir: Delivered a targeted Protobuf upgrade and cross-platform build stability improvements. The work included enabling s390x architecture support, addressing macOS build issues, and updating tooling to reflect the new protobuf version and dependencies like absl. These changes were implemented with a focus on reducing build failures, expanding platform coverage, and strengthening the CI pipeline for easier maintenance and faster onboarding for downstream users.

Month: 2025-05 — Stabilized onnx-mlir image builds by implementing a workaround for pip3 symlink creation in ubi8 amd64, removing Python 3.12 when present to prevent conflicts. This reduces CI failures and accelerates release readiness.

November 2024 performance summary focused on advancing compatibility and platform coverage across two repos, with an emphasis on delivering business value through up-to-date core components and broader architecture support.
