We are pleased to announce the release of yt 2.6. This is a major
release that includes new features and major updates along with all the
bugs identified and fixed since the release of 2.5.5 on August 28. We
currently plan for this to be the final major release of the yt 2.X
release series, although bug fix releases will continue for the
Please forward this email to other interested parties.
Most notable changes include:
* Relicensing whole project to BSD 3-clause
* Automated absorption line fitting module developed by Hilary Egan
* Significant improvement in documentation in a joint effort of the dev
team led by Cameron Hummels
* Documentation now includes inlined IPython notebooks, thanks to
* RAMSES, ART, Tiger, Maestro and Castro frontends removal as their
counterparts in 3.0 branch exceeded them both performance and capability
wise. All users of the aforementioned codes are strongly advised to
migrate to yt-3.0
* Python stack update, which now features: ipython-1.1.0, hg-2.8,
* New ProfilePlot and PhasePlot classes thanks to Britton Smith, Nathan
Goldbaum and Matt Turk. Previous mechanisms (i.e. profiles using
PlotCollection) are deprecated and will be removed in future versions.
* Projections of the Sunyaev-Zeldovich effect using SZpack implemented
by John ZuHone
* Generating Mock X-ray Photons now possible thanks to John ZuHone
* Introduction of Transfer Function Helper by Sam Skillman
* Initial support for installing yt with the package management system
* The addition of a frontend for the Pluto code by Andrew Myers
* The addition of an OBJ exporter to enable transparent and
multi-surface exports of surfaces to Blender and Sketchfab by Jiill Naiman
* yt can now export to RADMC3D thanks to Andrew Myers
* Considerably (10x+) faster kD-tree building for volume rendering
thanks to Sam Skillman
* Full integration and demonstration of all available colormaps
included in documentation thanks to Cameron Hummels
There have also been a number of minor bugs fixed in this release. Some
* Center of the plot in off_axis_projection plots is now calculated
correctly, thanks to William Gray
* Several enhancements to PlotWindow made by Nathan Goldbaum:
- Save accepts paths to directories
- Better handling of highly rectangular domains
- Axes and colorbars are now toggleable
- Nicer output in ipython notebook
- eps_writer is now compatible with PlotWindow, thanks to John Wise
* yt command line enhancements thanks to Devin Silvia and Matt Turk
* Several enhancements to Athena frontend by John ZuHone
* Improvements for OSX support (up to Mavericks)
* Updates to halo finding routines by Britton Smith
We’d also like to recognize the new contributors to the yt 2.x source
code and documentation during the yt 2.5 development cycle:
* Hilary Egan
* John Forbes
* William Gray
* Stuart Mumford
* Jill Naiman
* Doug Rudd
* Noel Scudder
* Elizabeth Tasker
If you are using the stable branch of yt from an installation script,
you can upgrade using "yt update" or "yt update --all" to upgrade your
full dependency stack. If you are using the development branch, you
may already have these fixes. A tarball of this release has been
uploaded to the Python Package Index (PyPI).
Documentation for this release is available at:

Thank you very much,
Kacper, on behalf of the yt development team

All outstanding PRs have been merged into yt-docs, all remaining

In a few minutes I'm heading to bed, so that all you guys on the other
side of the Pond have some time to take a deep breath and make sure we
hadn't forgotten about anything ;-)
If there are no replies to this thread, I'll send it first thing tomorrow.
There was a lot of churn last night in preparation for the release, which should happen in the next couple of days.
There is an updated build on the website now:
The docs really look great. I’m glad that so much work has been put into improving them - I think they will be much more useful for our users going forward. Even better, with the new inline scripts and notebooks there is a solid platform to add great looking and useful content in the future.
If anyone has some spare time, it would be great if we got some eyes on the docs build to look for typos or formatting errors.
Cameron just pinged me about a docs issue with a Sizemore about the 2.6
release happening on Friday. Can we hold off on that for another week or
two? I'd like to be able to work on ProfilePlot and PhasePlot this weekend.
I recently subscribed to the [yt] tag on StackExchange. Now, whenever a question is asked using this tag on any StackExchange site, I will get an e-mail about it, just like if a question is asked on the users or dev list. Currently (as far as I can tell) zero questions have been asked using this tag...
If there are a few others who are interested in subscribing to the tag, I think it might be worthwhile to add StackOverflow to the website and docs where we describe how to get help and also announce on the user’s list that StackOverflow is an alternate place to ask questions.
While this might split the community somewhat - not everyone will be subscribed to StackOverflow and thus might miss useful info - I think moving some helpful suggestions to StackOverflow will massively improve googleability of common yt issues, allowing us to avoid answering the same questions over and over again.
It might also be worthwhile to ask and answer some common yt questions. Off the top of my head, I think we could at least answer how to load various types of datasets into yt.
are off axis projections expected to work for all frontends in 3.0? Using
Ramses I'm getting some curious results. e.g.
p = OffAxisProjectionPlot(ds, [.1, .1, 1], 'Density', north_vector=[0,1,0])
where the whole simulation seemt to be squished into one quadrant.
