Tracking issue for rc1

[codesections]

As noted on the issues page, there are several auxiliary issues (mostly docs and tests) that I would like to get done before we actually launch 1.0.0. However, I am not currently aware of any technical issues that would prevent us from announcing a release candidate while finalize those auxiliary matters.

It makes sense to give the current level of testing at least a bit more time before we do so, and this issue can track any blockers that come up. But, if the current testing doesn't expose any significant issues, it may make sense to publish an rc1 release soon.
