Oct 1, 2025Month 2025-10 — NVIDIA/cuopt: Key contributions centered on test reliability and packaging modernization. PDLP solver tests were stabilized by correcting solver usage, explicitly configuring PDLP in tests, and addressing a CI race condition in UCX, significantly improving test reliability. Packaging and dependency management were upgraded and harmonized to better align with newer core libraries, streamline builds, and reduce distribution size. Packaging hygiene improvements included removing unused libraries and files from the conda package and updating the Rapids logger, resulting in smaller artifacts and a smoother release process.

Aug 1, 2025August 2025 monthly summary for NVIDIA/cuopt: Key release readiness actions for cuOpt 25.10, including dependency upgrades across configuration, build scripts, and docs; alignment of cuopt-server and cuopt-sh-client to 25.10.*. Local search reliability improved by renaming timer to ls_timer in generate_more_solutions, preventing timing-related issues. Code style cleanup and consistency improvements implemented with no functional changes. These efforts accelerate release readiness, stabilize the local search workflow, and improve long-term maintainability and documentation accuracy.
