We're proud to announce the release of yt version 1.7, an analysis and<br>
visualization toolkit for Adaptive Mesh Refinement data. (Just in<br>
time for the Enzo Workshop!) This release fixes a number of bugs, as<br>
well as numerous improvements to the code base and the documentation.<br>
<br>
Most prominently, it features "two-point functions" such as structure<br>
and correlation functions, a re-engineered volume rendering interface,<br>
multivariate volume rendering, off-axis projections, and a mechanism<br>
for complex postscript plot layout. Additionally, a major aspect of<br>
the drive to 1.7 has been re-engineering the API documentation to be<br>
better suited to interactive help (the "help(...)" call in python) as<br>
well as the documentation website ( <a href="http://yt.enzotools.org/doc/" target="_blank">http://yt.enzotools.org/doc/</a>
).<br>
<br>
Some of the changes since yt-1.6 (Released on January 22, 2010) include:<br>
<br>
* Direct writing of PNGs<br>
* Multi-band image writing<br>
* Parallel halo merger tree<br>
* Parallel structure function generator<br>
* Image pan and zoom object and display widget<br>
* Parallel volume rendering<br>
* Multivariate volume rendering, allowing for multiple forms of<br>
emission and absorption<br>
* Added Camera interface to volume rendering<br>
* Off-axis projection<br>
* Stereo (toe-in) volume rendering<br>
* DualEPS extension for better EPS construction<br>
* Rewritten, memory conservative and speed-improved contour finding
algorithm<br>
* Speed improvements to volume rendering<br>
* Preliminary support for the Tiger code<br>
* Lightweight projection loading with projload<br>
* Improvements to yt.data_objects.time_series<br>
* Improvements to yt.extensions.EnzoSimulation<br>
* Speed improvements to basic HOP<br>
* Better docstrings and documentation<br>

<br>
yt features native support for Enzo<br>
(<a href="http://lca.ucsd.edu/projects/enzo" target="_blank">http://lca.ucsd.edu/projects/enzo</a>)
data, providing a natural and<br>
intuitive way to address physical regions in space as well as<br>
processed data.<br>
<br>
Installation instructions can be found here:<br>
<a href="http://yt.enzotools.org/doc/installation.html" target="_blank">http://yt.enzotools.org/doc/installation.html</a>
. If you are running an<br>
older version of yt, re-obtaining and re-running the installation<br>
script should happily upgrade your installation. yt is a Free and<br>
Open Source project, and we invite you to get involved. For more<br>
information, join the yt-dev mailing list, or see the hacking<br>
guidelines on the Wiki: <a href="http://yt.enzotools.org/wiki/HackingGuidelines" target="_blank">http://yt.enzotools.org/wiki/HackingGuidelines</a><br>
. We anticipate a few more releases in the 1.7 series as<br>
documentation and docstring coverage progress.<br>
