Right now we only have one more significant issue left for 3.3. I've talked with Cameron about it and he'd like to see it fixed so trident works correctly with yt-3.3.0. I'm expecting him to have a patch ready or to let us know that he's punting on it in the next few days.
That means that if you have any bugfixes you'd like to see by part of yt 3.3.0, now is a good time to put them together.
Please also keep in mind that we will be doing a bugfix release (yt 3.3.1) within a month or so of the initial release, sooner if someone pokes me or if something urgent comes up.
I will coordinating with andrew to manage getting the release e-mail out after we have binary wheels and conda packages available via conda-forge, so there might be a day or two between tagging the release and actually publicly announcing it.
