On behalf of the Trident development team, I am happy to announce a new stable release of Trident, a python-based code suite for analyzing astrophysical hydro simulations to investigate the CGM/IGM and produce synthetic absorption spectra. This release is accompanied by a shift in development from mercurial/bitbucket to git/github, continuous integration and testing with travis, and a number of bugfixes and additional features. Our changelog (below) has a full description of the changes in this version. Full installation instructions are available in our documentation, as are instructions for a number of common use cases in working with your datasets: e.g., adding arbitrary ion fields, making column density maps, calculating column densities of individual sightlines, generating absorption line spectra. There has also been recent development in the yt community to treat particle-based datasets more natively rather than by depositing to a grid and then processing. This effort, nicknamed "*demeshening*", is being led by Nathan Goldbaum, Meagan Lang, and Matt Turk, with Trident contributions by Bili Dong and myself. Not only does it get more accurate results, but it is faster and uses less memory since particle fields don't need to be deposited to a global grid. This code is now in beta, and users are encouraged to use it and give bug reports. There are full instructions for installation of it available in the Trident docs, and we expect the next stable release of Trident will incorporate it. Please don't hesitate to contact the mailing list with any questions or problems you may encounter with the code, and I encourage you to share this announcement with other scientists who may be interested in using Trident. *Trident Page:* http://trident-project.org *Trident Code:* https://github.com/trident-project/trident/ *Trident Docs:* https://trident.readthedocs.io/en/latest/ *Trident Paper*: http://adsabs.harvard.edu/abs/2017ApJ...847...59H *Changelog to Trident 1.1:* https://trident.readthedocs.io/en/latest/changelog.html *Installation Docs for beta "demeshened" yt and Trident:* https://nbviewer.jupyter.org/url/trident-project.org/notebooks/trident_demes... --The Trident Developer Team: Cameron Hummels Britton Smith Devin Silvia Matthew Turk Nathan Goldbaum Kacper Kowalik Lauren Corlies Bili Dong Hilary Egan Clayton Strawn -- Cameron Hummels NSF Postdoctoral Fellow Department of Astronomy California Institute of Technology http://chummels.org
