Hi there,
Tonight I'm merging a bunch of changes from me, Britton Smith, John
Wise and Stephen Skory back into the trunk from the mercurial
repository. If you're running on the yt-1.5 source tree, this won't
affect you -- but if you're running on trunk, the next time you update
you will have to rerun "python2.6 setup.py develop" or "python2.6
setup.py install" depending on how you installed. If you used the
install script, you should also be able to re-run it at any time to
get an updated source tree and installation.
There are no pressing fixes in this, only speed and memory
improvements, so don't feel it's necessary to make the jump just now
if you're happy with where you are. If you do update, here's a minor
changelog:
* Hierarchy is much faster, and the .yt file now only stores data
products, all hierarchy info goes into a .harrays file (for forward
compatibility with Enzo)
* The attributes off the hierarchy for grids: gridLeftEdge and
gridRightEdge are now grid_left_edge and grid_right_edge, in keeping
with our coding standards
* Hierarchy has been rewritten for *clarity*
* The bug with DM-only sims has been fixed
* IO routines have been refactored and very cleaned up
* Preliminary particle IO readers have been added -- much, much
faster, but not yet production-ready
* New cloud-in-cell deposit function without needing fortran
* Some other minor things to support coming features
All the public and primary functions, classes etc should be the same.
Thanks, and let us know if there are ANY problems!

Hi Guys,
I am (trying) to use the find_clumps routine to identify clumps in my data
and I would then like to visualize it. How do I get the data from the
find_clumps routine into the callback: p.modify["clumps"]() so I can put it
on projections/slices? What should it then look like?
Many thanks,
Libby

Hi all,
I am getting this error <http://paste.enzotools.org/show/257/> when I attempt to instantiate the grid hierarchy.
Here is my restart file <http://paste.enzotools.org/show/258/> and the corresponding hierarchy file <http://paste.enzotools.org/show/259/>. Does anyone see anything obviously wrong? I'm attempting to analyze a DM-only run with 2x grid to particle resolution, so I might have fudged something up.
Thanks!

We're proud to announce the release of yt version 1.5, an analysis and
visualization toolkit for Adaptive Mesh Refinement data. yt features
native support for Enzo (http://lca.ucsd.edu/projects/enzo/) data,
providing a natural and intuitive way to address physical regions in
space as well as processed data. Version 1.5 features many new
improvements, most prominently that of the addition of parallel
computing abilities and generalization for multiple AMR data formats.
Additional improvements include:
* Fully rewritten documentation, featuring a new cookbook with
downloadable recipes and commenting facilities
* Extensive methods section of documentation
* Fully parallel slices, projections, cutting planes, profiles, quantities
* Parallel HOP halo finder
* Friends-of-friends halo finder
* Object storage and serialization
* Major performance improvements to the clump finder (factor of five)
* Generalized domain sizes
* Generalized field info containers
* Dark Matter-only simulation support
* 1D and 2D simulation support
* Better IO for HDF5 sets
* Support for the Orion AMR code
* Spherical re-gridding of data
* Automated halo profiler and imager
* Limited non-axially aligned projection support ("disk stacking")
* Light cone generator
* Callback interface improved
* Several new plot overlay callbacks
* New data objects -- ortho and non-ortho rays, limited ray-tracing
* Fixed resolution buffers
* Spectral integrator for CLOUDY data
* Substantially better interactive interface
* Performance improvements *everywhere*
* Command-line interface to *many* common tasks
* Isolated plot handling, independent of PlotCollections
Installation instructions, documentation, recipes, mailing list info
and assorted other items can be found at the website,
http://yt.enzotools.org/ .
This release is the product of a year of work by the development team,
and we are very proud of the results and happy with what we have to
offer. Thanks very much!
Sincerely,
The yt development team:
