[ScottTodd]

Overview

Our previous stable release was cut on 2024-08-28: https://github.com/iree-org/iree/releases/tag/candidate-20240828.999. We aim for roughly one stable release per month. This issue tracks the release process for the next release.

Release process docs:

• https://iree.dev/developers/general/release-management/
• https://github.com/iree-org/iree/blob/main/RELEASING.md

Release checklist:

• Watch for major/breaking changes and decide to either batch them with this release or defer them until the next release
• Choose a release candidate from nightly releases to promote. The candidate should contain no major regressions and should include all packages, even those marked experimental in .github/workflows/build_package.yml like macOS and Windows packages.
• Compile release notes
• Promote to stable (on GitHub) and push packages to PyPI
• Roll forward downstream packages like iree-turbine and push similar package updates to PyPI
• Update release process docs for next time
