@daspecster If you go to https://github.com/GoogleCloudPlatform/gcloud-python/releases/new what kind of error message do you see?

/cc @jgeewax May need your help adding him to a group to resolve.

[daspecster]

@dhermes actually that link takes me back to github.com.
Also, I updated the release notes with your doc.

[dhermes]

OK we can wait on @jgeewax before merging this.

[daspecster]

@dhermes Is this good to go now?

[dhermes]

There have been some merges since Friday so you should rebase against master and re-check the merged PRs. (Thanks for pinging me.)

[daspecster]

Ok will do!

[daspecster]

@dhermes, I updated the release copy. Let me know what you think!

[tseaver]

@daspecster I tweaked the release notes text a bit.

[daspecster]

Awesome! Thanks @tseaver!
