Hi folks, Just a heads up that we're going to merge https://github.com/yt-project/yt/pull/2711 soon. This takes some code that was yt specific and moves it to an external package (where perhaps it can find use outside of yt). The only impact this will have is if you are accustomed to installing yt from source, where you will now need to also have this installed. If you are used to using yt from conda, pip, etc, then the dependency resolution will pick up the change and install it. *But*, if you are installing yt from source, you'll also need to install 'ewah_bool_utils' which is located at: https://github.com/yt-project/ewah_bool_utils , as well as on conda-forge, pypi, etc. -Matt
