Today I prematurely merged the pull request that adds the new default colormap. This was on me for not being careful to make sure the tests were passing before hitting the merge button.
Kacper helpfully suggested on Slack that the yt-fido bot should be able to "approve" pull requests when the tests pass. This should help us more easily see that a pull request is passing the tests just by glancing at the header for the pull request. I've opened an issue to track this here:
The tests were broken for an hour or so, but were fixed by merging PR 2090, so hopefully the disruption was minimal. Sorry for the mistake - I will try to be more conscientious about merging pull requests going forward.
