Hello yt friends! 

On behalf of everyone who contributed, the yt community is delighted to announced that yt 3.6.0 has been released! Version 3.6.0 is our next release after 3.5.1 which was in February 2019. We anticipate that this will be the final major release in the 3.x series, and that the next major release will be 4.0. Additionally, yt 3.6.0 does not support Python 2, although we have not removed the compatibility layers (such as six). 

It includes changes from 184 pull requests, contributed by 39 unique contributors, 22 of which committed their first time to the project.

We’ve also updated our project governance and contribution guidelines, see here: https://yt-project.github.io/governance/ ; the yt homepage itself is at https://yt-project.org/ and the GitHub project page is at https://github.com/yt-project/yt

For full release notes, see https://yt-project.org/doc/reference/changelog.html#version-3-6-0 .

Binaries for yt 3.6.0 are available via pip and conda. If you installed via the install script or use conda to manage your python installation, you can update yt via:

$ conda update -c conda-forge yt

And via pip if you manage your python installation with pip:

$ pip install -U yt

As always, if you have any questions, concerns, or run into any trouble updating please don’t hesitate to send a message to the mailing list or stop by our Slack workspace.

Since the last release, support for these new data formats has been added:

* AMRVAC – thanks to Clement Robert and Niels Claes for their hard work supporting this and many associated changes in yt!
* AdaptaHOP

New features and major changes:

* Angular momentum vector directions have been reversed, which is a breaking change with past versions.
* CartoPy is now supported as a source of projections and transformations for appropriate geometries, and plotting geographic and georegistered data is much simpler and streamlined!
* Cut regions can now be made using the operators beginning with exclude_ and include_, to simplify their creation.
* Field definitions and small arrays are now IPywidget-ized!
* Curvilinear coordinates have many additional plot annotations supported
* Fields can be added to compute “nearest value” with particles.
* Ghost zone generation has had some hotspots optimized for improved performance
* Regularized grids (covering, arbitrary and smoothed) can be exported to xarray format
* Data objects can be exported to AstroPy QTables and pandas dataframes
* The colormap turbo, a CVD-friendly version of jet, is now available
* Wheels, conda packages and the like are available at all the usual places.

Breaking changes:

Please be advised that PR 2043 introduced a breaking change where the angular momentum has been reversed. This may modify your results, so please note these changes if you use angular momentum in your work. 

Thanks again to everyone who has contributed to this release! We are incredible grateful for this community and the contributions supplied by everybody.

Please forward this announcement on to any interested parties.
