• Upload release to test PyPI
• Upload release to PyPI.

code to publish to PyPI (summary)

mkdir /tmp/lgb-release
cd /tmp/lgb-release

NEW_VERSION="4.3.0"

# NOTE: requires a GitHub personal access token with "repo" scope
gh release download \
    --repo microsoft/LightGBM \
    --dir ./artifacts \
    --pattern 'lightgbm*-py3-*.whl' \
    --pattern "lightgbm-${NEW_VERSION}.tar.gz" \
    "v${NEW_VERSION}"

twine upload \
    -r testpypi \
    ./artifacts/*

(gh is the GitHub CLI, see https://cli.github.com/manual/gh_release_download)

Then confirmed that installing the latest wheel works.

pip install -i https://test.pypi.org/simple/ "lightgbm==${NEW_VERSION}"
python ./examples/python-guide/logistic_regression.py

Then pushed them to real PyPI.

twine upload \
    ./artifacts/*

• Update cran-comments.md when new release is accepted on CRAN.
• Upload release to NuGet.
• Update version and commit hash in Homebrew formula (docs)
• put up another PR incrementing development version here in GitHub (example: bump development version to 4.1.0.99 #6090)

Notes for Reviewers

I believe this should be v4.3.0 instead of v4.2.1 because of the two breaking changes:

• [cmake] [c++] require CMake 3.18+ #6260
• [R-package] remove readRDS.lgb.Booster() and saveRDS.lgb.Booster() #6246

This release is being put up so soon after v4.2.0 mainly to try to prevent CRAN from archiving the package

[jameslamb]

/gha run r-valgrind

Workflow R valgrind tests has been triggered! 🚀
https://github.com/microsoft/LightGBM/actions/runs/7551841465

Status: success ✔️.

[jameslamb]

Since all of the R tests (including valgrind and a few I submitted via rhub) are passing here, I've built the CRAN package and submitted it to CRAN as v4.3.0.

Submitted with this note:

This version contains changes which we believe will fix the issues reported in CRAN's 'clang18' checks (https://www.stats.ox.ac.uk/pub/bdr/clang18/lightgbm.log). We've tested those changes using images from rhub (#6265), configured based on CRAN's "Additional Issues" notes at https://cran.r-project.org/web/checks/check_issue_kinds.html.

In the future I don't want to do that outside of the normal release process with approvals and review, but I thought it was necessary to act quickly given the short deadline from CRAN.

[jameslamb]

Separately, there are some non-R CI failures blocking this PR. I think they may be blocking all PRs... I see them on the most recent master build, for example. (build link)

I have limited time to spend on LightGBM the next few days, but can try to look into those (and document them in a separate issue) if no one else is able to get to them first.

[jameslamb]

I've built the CRAN package and submitted it to CRAN as v4.3.0

Happy to say the package was accepted to CRAN! The clang18 check warning is gone at https://cran.r-project.org/web/checks/check_results_lightgbm.html and the package is passing almost all of CRAN's checks (just r-patched-linux-x84_64 has not been run yet).

Updated cran-comments.md in 63d71f6.

there are some non-R CI failures blocking this PR

Documented in #6282.

Investigating in #6283.

[jameslamb]

Add release branch to RTD versions, trigger a new build, check docs

docs build for this release is passing: https://readthedocs.org/projects/lightgbm/builds/23200920/

and the docs look good to me:

• https://lightgbm.readthedocs.io/en/release-v4.3.0/
• https://lightgbm.readthedocs.io/en/release-v4.3.0/R/reference/

[jameslamb]

... test on M1/M2 Mac

The R package is passing CRAN's checks on an arm64 mac: https://www.r-project.org/nosvn/R.check/r-release-macos-arm64/lightgbm-00install.html

I'll test on my M2 laptop in a bit (just waiting on some software updates).

[jameslamb]

@guolinke @jmoralez @shiyu1994 @borchero could you please take a look and let me know if you agree with releasing the current state of this branch (which is up to date with master) as v4.3.0?

[jameslamb]

Built and tested the Python package on my M2 Mac (macOS Sonoma 14.3) tonight.

sh build-python.sh bdist_wheel --nomp
pip install dist/lightgbm*.whl
pytest tests/python_package_test

I used --nomp because I was finding deadlocks that I think might have been caused by different libomp being found at build time vs. runtime (#4229 (comment)).

All tests except the Arrow ones passed. The Arrow tests all failed.

I don't think the changeset in v4.3.0 here is the cause of either of these issues, and they seem limited to the arm64 Macs.

I don't think they should delay this release, and that we can focus on fixing them (and various other macOS support issues) in the next release.

[shiyu1994]

LGTM. Thanks!

[jameslamb]

Thanks all! I'll continue with the release.

[jameslamb]

Ran the following to create the v4.3.0 tag and update the stable tag.

git fetch upstream --tags
git tag -d stable
git push upstream :refs/tags/stable
git tag stable
git tag v4.3.0
git push upstream stable v4.3.0

(NOTE: I alias this repo to upstream and my fork to origin in my git settings)

https://github.com/microsoft/LightGBM/tags

That triggered an Azure DevOps build which should create the release automatically:https://dev.azure.com/lightgbm-ci/lightgbm-ci/_build/results?buildId=15709&view=results. This takes around 90 minutes (because of the QEMU CI job).

I'll do the remaining tasks tomorrow.

[jameslamb]

v4.3.0 release has been created: https://github.com/microsoft/LightGBM/releases/tag/v4.3.0

[jameslamb]

Update version and commit hash in Homebrew formula

Homebrew/homebrew-core#160920

[jameslamb]

Upload release to test PyPI
Upload release to PyPI.

This is done, and tested that the wheels installed from there work (on my intel mac).

https://pypi.org/project/lightgbm/#files

[jameslamb]

Add new tag to RTD versions and trigger a new build.

These are done. v4.3.0 now available on readthedocs.

• successful build:https://readthedocs.org/projects/lightgbm/builds/23238180/
• version-pinned docs:
  • https://lightgbm.readthedocs.io/en/v4.3.0/
  • https://lightgbm.readthedocs.io/en/v4.3.0/R/reference/

[jameslamb]

Upload release to NuGet.

done

[jameslamb]

put up another PR incrementing development version here in GitHub

#6287

And with that, this release is done. Thanks everyone!

[jameslamb]

For future reference... I added some code snippets to the PR description here to hopefully make it a little easier to cut the ext release.

Maybe in the future if we start releasing more frequently, it'd make sense to check those into the repo.
