The yt community is proud to announce the release of yt 3.3.2! yt (http://yt-project.org) is an open source, community developed toolkit for the analysis and visualization of volumetric data of all types, with a particular emphasis on astrophysical and nuclear engineering simulations. yt 3.3.2 is a bugfix release that includes a number of fixes and enhancements for issues discovered after the release of yt 3.3.1. We urge all yt users to update to the latest version. If your python installation is managed via conda, update following: $ conda update -c conda-forge yt If your python installation is managed via pip, update following: $ pip install -U yt Finally, if you manage your yt installation by running out of a clone of the yt mercurial repository, update following: $ yt update We would like to thank the following people for their contributions to this release: Corentin Cadiou Nathan Goldbaum Cameron Hummels Suoqing Ji Ben Keller Chang-Goo Kim Kacper Kowalik Alex Lindsay Andrew Myers John Regan Mark Richardson Rafael Ruggiero Hsi-Yu Schive Britton Smith Matthew Turk John Wise Michael Zingale John ZuHone A summary of changes in this release, along with the number of the pull request implementing the change follows below: * Ensure package data files are installed to the correct location (PR 2425) * Ensure particle profile date are interpreted in the correct units for Enzo data (PR 2423) * Work around an issue with reading FLASH 2.5 data using the latest release of h5py. (PR 2421) * Update docstrings for RockstarHaloFinder (PR 2416) * Convert the axis argument of the argmax function to a list if it is not one already (PR 2414) * Make the annotate_clear callback return an instance of the plot for improved user experience in the Jupyter notebook (PR 2413) * Explicitly use integer divion to avoid reading in incorrect grid data in python3 (PR 2412) * Suppress logging when searching for datasets in a simulation time series (PR 2409) * Update instructions on how to set the log level for the yt logger in the documentation (PR 2400) * Various bugfixes for the light ray functionality. These fixes will impact answers generated by the Trident code.

(PR 2354) * Fail more gracefully if yt loads a FLASH dataset with accompanying particle file and the particle file is not from the same simulation time as the plot file. (PR 2353) * Fix an issue with locally defined derived fields not generating correct colorbar labels (PR 2351) * Avoid mutating a YTArray passed into the YTArray initializer (PR 2347) * RAMSES fields and parameters with units of time are now read in correctly for cosmological simulations (PR 2346, PR 2374) * Print a nicer error message when trying to create a profile object that mixes particle and mesh fields (PR 2338) * Ensure the FixedResolutionBuffer object associated with PlotWindow plots is regenerated before it is used again if it is invalidated. (PR 2335) * Fix an issue that would cause incorrect units to be used if units are passed in at dataset load time with units_override (PR 2334, PR 2407) * Add gravitational_potential as a known field in the Athena frontend (PR 2333) * Make 'metallicity' a known field in the stream frontend (PR 2331) * Prevent a segmentation fault in the volume renderer by accounting for round-off error.
