Release managers need to go through this check list and ensure all tasks are done

  • Bump the version
  • Follow the check list for cuda-core below for the remaining steps
• Is this release for cuda-core?
  • File an internal nvbug to communicate test plan & release schedule with QA
  • Ensure all pending PRs are reviewed, tested, and merged
  • Bump the version
  • Create a public rc tag
  • Point QA to fetch public artifacts (wheels) from the GHA run ID, example: gh run download 12323257563 -p "cuda-core*" -R NVIDIA/cuda-python
  • Wait for QA reports and fix any issues found
  • Finalize the doc update, including release notes
  • Update the docs for the new version
  • Create a public release tag
    • If any code change happens, rebuild the wheels from the new tag
