Hi folks, As a heads-up, the yt-4.0 => master merge is now passing the unit tests on Travis: https://github.com/yt-project/yt/pull/2437 https://travis-ci.org/github/yt-project/yt/builds/676363892 (I had to push a quick update after a conflict showed up, so as of this writing the new results aren't yet finished.) Note that the travis minimal answer tests are not passing, which is likely a result of the merge and matching values between branches of the answer-store subrepo. I'm not sure yet the best way to proceed with changing to using pytest for answer tests, but I'm going to try to connect with Jared and see if we can strategize something to propose here. -Matt
