Looks like we've got another flaky test :(

[giladgray]

@llorca flaky test? things look good to me.

edited release notes to provide context on new labs props, moved some more things to Documentation section.

need more context on Table new feature: what issue does this fix? can we describe it differently to capture the WHY?

[cmslewis]

@giladgray done

[cmslewis]

LGTM. Thanks @llorca!

[llorca]

@giladgray yeah I had to manually retrigger the build. Focus stuff again https://circleci.com/gh/palantir/blueprint/3945

[tgreenwatts]

Um given that #1515 seems to be broken again, should we remove it from the notes?

[tgreenwatts]

Actually I take it back. It appears to work on this PR. It didn't on other recent table ones, but maybe they were just based on older code?
