@andygrove @alamb Looks like we can start to automatically generate pull requests and issues using the GitHub APIs.

[alamb]

Thanks @iajoiner -- I am working on a script for #2727 now

[iajoiner]

@alamb Thanks! I will file the PR for the release PR generation script now and then another one for the issue generation script by Monday. The amount of repetitive human work for releases should be further minimized.

[alamb]

FYI @iajoiner -- here is my hacky python script to update github labels

It does appear to work... But is definitely a bit of a hack

[alamb]

@iajoiner when I ran the update_changelog.sh script locally it modified the CHANGELOG-old.md file (even though that file already had the old changelog and probably shouldn't be updated again)

[iajoiner]

@alamb I think we can modify the script and either an argument or detect whether CHANGELOG-old.md is already up-to-date. I prefer the latter and will make the changes next week.

It seems a bit odd that we have both issues and PRs in here, perhaps we could exclude api-change from the auto-label, otherwise it obfuscates what the actual breaking change was?

[alamb]

I agree -- I think this issue was marked with api-change by an earlier version of the script -- I have subsequently blacklisted (won't transfer) api-change labels to issues and will fix this one manually

[alamb]

I forgot to update a version in the toml files: #2748
