Why is this needed?

Regular patch releases are vital to ensure our users have bug-free and secure software.

how about including #18480 in it.

[JalinWang]

Do you consider this PR merged in 2021?

@liangyuanpeng, I think it would be reasonable to add the bbolt version bump. We have #18488 and #18489, which are very close to being merged.

@JalinWang, being this technically an (experimental) feature, I would like to hear @ahrtr / @serathius thoughts on this.

I have no objection on this. Please also see #13018 (comment)

[ivanvc]

@JalinWang, do you want to help backporting #13018 to release-3.5 (after we merge #18495)?

[JalinWang]

@JalinWang, do you want to help backporting #13018 to release-3.5 (after we merge #18495)?

Sure. I will create a backporting PR per https://github.com/etcd-io/etcd/blob/4d42c0f86ac2762253a804fc5d9e6a25b80ef21b/Documentation/contributor-guide/release.md#patch-version-release (, where says the backporting commits "should be restricted to bug fixes and security patches" ? )

Update: I found the discussion about backporting here. The criteria seems to be not that clear :(

@JalinWang, with Benjamin's approval, feel free to do the cherry-pick :)

[ArkaSaha30]

Hello @ivanvc , I would want to shadow the release of v3.5.16

[ivanvc]

Hi team (@ahrtr, @jmhbnz, @serathius, @spzala, @wenjiaswe), similar comment to the one from #18486. Would you want to be part of the release team for 3.5.16? I'm happy to lead this one, too, if needed.

[ivanvc]

Hi @ArkaSaha30, can you help to do a pass on pull requests and issues that need to be backported? I'm using the following search: https://github.com/etcd-io/etcd/issues?page=1&q=is%3Aissue+label%3Atype%2Fbug+created%3A%3E%3D2024-07-20, and https://github.com/etcd-io/etcd/issues?q=is%3Apullrequest+label%3Atype%2Fbug+created%3A%3E%3D2024-07-20.

Thanks!

[jmhbnz]

Thanks for volunteering to lead 3.5.16 and 3.4.34 @ivanvc!

I see @ahrtr has agreed to be release advisor for 3.4.34, I am happy to be release advisor for 3.5.16.

I'm just coming back after being sick so I'll do some scope/backport review soon. Keen to set a date for the release and book in the release call 👍🏻
