I guess it was a typo.

ah!! yes, thank you. Maybe in the future we should have a script that automates these changes, like my colleagues do in the RAPIDS repos: https://github.com/rapidsai/cuml/blob/branch-24.08/ci/release/update-version.sh

@jameslamb there'd also be https://pypi.org/project/setuptools-scm/ :)

Very sorry for resolving this without answering you @borchero , that was unintentional.
I'm -1 on using tools like setuptools-scm or versioneer here. In my experience, they introduce much more complexity than they reduce, at least for projects like LightGBM with a linear sequence of releases (no long-term-support branches, backporting, etc.).
For example, they can be the source of hard-to-debug differences between local and CI builds, unless you're diligent about running git fetch upstream --tags or similar regularly.
You might find some of the other discussion in https://discuss.python.org/t/please-make-package-version-go-away/58501 interesting (although I don't agree with the original post... I believe we should continue to support lightgbm.__version__).

Yes I meant "instead of v4.4.1", just edited it. Sorry for all the typos 😅 |

Seems that Azure Pipelines builds are constantly failing for the
For example, the latest one link: https://dev.azure.com/lightgbm-ci/lightgbm-ci/_build/results?buildId=16597&view=results Failing jobs are:
Should these fails be a blockers for this release? |
I'll check again once we're done merging changes here. |
Oh wow, yes I hadn't realized that most I do think we should try to figure this out for the release, but let's not block releasing the R package on them. If we get to, say, July 30 and have still not fixed it, I think we should at least do a release of the R package to CRAN, to avoid it being archived there. Could you document these CI failures in a separate issue, and we could discuss further there? I'm linking this relevant thing I found, that suggests that one issue could be a very long filepath on Windows: sarugaku/shellingham#8. Maybe that could explain the jobs only failing on |
Sure, done!
Absolutely agree! |

requested review from

I received the following email from CRAN (Prof Brian Ripley) 3 days ago.
I believe we should release the current state of this PR as v4.5.0 as soon as possible. I want to allow enough time for CRAN to reject the package and for us to put up another submission prior to their summer shutdown. I do not think there are any other open PRs or issues that absolutely MUST be addressed in this release. @guolinke @borchero @jmoralez @shiyu1994 @StrikerRUS could you please review, and approve if you agree? I'd like to get at least 2 approvals (and at least 1 from either @shiyu1994 or @guolinke ) before releasing. |
|
@guolinke or @shiyu1994 could you please review? I'd like to try to submit to CRAN as soon as possible, and really think one of you 2 should always approve a release. If you'd like to change that in the future and are ok with me + some other maintainers doing minor releases without requiring your approval, let me know. |
|
I think we should stop merging any non-trivial PRs before CRAN response. It should help to avoid situation similar to the following one: #4930 in case we will need |
|
Agreed! I'll merge this so we can start the process of releasing. And I'll post follow-up comments here as I've done in previous releases. Thanks for the reviews and help everyone! |

Ran the following to create the git checkout master
git pull upstream master
git fetch upstream --tags
git tag -d stable
git push upstream :refs/tags/stable
git tag stable
git tag v4.5.0
git push upstream stable v4.5.0(NOTE: I alias this repo to 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=16722&view=results This takes around 90 minutes (because of the QEMU CI job). I'll check back in a few hours and continue the release then. |

One test job on the release failed, with what looked like a conda network error. Restarted it. |

done! The release is now live: https://github.com/microsoft/LightGBM/releases/tag/v4.5.0 |

This is done.

I haven't figured out a good way to make that automatic yet. They're built on GitHub Actions because (at least as of #6391), Azure DevOps didn't have an arm64 runner image. So they have to be manually added to the release. They can be found by clicking "🏠 Summary" on a run of the 
I just manually downloaded that artifact, unzipped it, and uploaded the file to https://github.com/microsoft/LightGBM/releases/tag/v4.5.0. |

Ah, I see! Thanks for the explanation! * Just checked - still no arm64 macOS runner at Azure 😞 |

I think we should add one more release TODO item: "update conda-forge version" since @jameslamb is now official lightgbm feedstock's maintainer. |
|
Agreed! I just added it here so we'll remember it when this PR's description is copied into the next release PR. |
put up a PR: #6578 |
done: https://www.nuget.org/packages/LightGBM/4.5.0 That should be fully published some time in the next few hours.

With that, I believe this release is complete! Thanks for the help, everyone. Really great having you back to help @StrikerRUS , the throughput in this project was great over the last month. This release covers just 6 weeks of changes, but included 49 commits from 16 different contributors (v4.4.0...v4.5.0). I'm very happy about that! |

@jameslamb Thank you very much for your hard work on the release! 💪 |
