HOOMD-blue 0.8.2 Released
The much-delayed HOOMD-blue 0.8.2 release is finally complete. The delays actually resulted in an extensive amount of testing and subsequent bug fixes making this a really solid release. We hope you enjoy it!
Major changes since 0.8.1:
- Performance enhancements
- Time varying quantities can now be given to various updaters (temperature and pressure, for example)
- update.box_resize added to change the box size slowly over many time steps
- run() commands can now be limited to a given wall-clock time (potentially useful on shared cluster with wall-clock time limits on jobs)
- Angle, dihedral and improper forces can now be specified
- Neighbor exclusions can now be changed to optionally include/exclude 1-2, 1-3, and 1-4 pairs.
- New command line options for controlling how HOOMD-blue uses the GPU - see the documentation for details
- Plus many bug fixes and other small improvements
See the change log for a more detailed list.
A big thanks goes to Axel Kohlmeyer, David LeBard, and Ben Levine from the ICMS group at Temple University for contributing many features to this release. Their biggest contribution is the angle, dihedral, and improper forces.

HOOMD is going blue!
HOOMD's lead developer has graduated and moved on to a position at the University of Michigan, and the center of HOOMD development is moving with him. Due to technical reasons regarding licensing, a name change must be part of the move. Thus HOOMD development will continue under the name HOOMD-blue! It stands for Highly Optimized Object-oriented Many-particle Dynamics -- Blue Edition.
If you are familiar with the language used commonly in open source projects, this is technically a fork of the original HOOMD project. For all practical purposes, however, it actually is not a fork as we have the same developers continuing to work on the code as if nothing happened. No major changes to the roadmap are planned and, if anything, the development effort will only accelerate after this move. Our apologies for any confusions this might cause, but such changes are inevitable with young projects developed by graduate students.
The new web URL for HOOMD is at http://codeblue.umich.edu/hoomd-blue/ and the server combines that directly with Trac and SVN hosting for the project at https://codeblue.umich.edu/hoomd-blue/trac/ and https://codeblue.umich.edu/hoomd-blue/svn/ respectively. The old website and SVN will be left up for a few months for continuity before they are taken down.
A new feature we are proud to offer on this Trac web is the ability for users, not just developers, to register accounts with the system. To do this, go to the Trac web page, click the register link in the upper right and follow the onscreen instructions. After verifying your e-mail address with the system, you will be able to edit and add to the wiki, post new tickets and add comments to existing tickets.
Getting this new page operational has been the major blocker delaying the release of 0.8.2. Now that we are up and running, expect this next packaged release soon!

Hotfix to HOOMD 0.8.0
A serious issue was discovered in the windows builds of HOOMD 0.8.0. Any use of dump.dcd would result in the hoomd executable crashing. This issue is fixed in hotfix binaries labeled version 0.8.0.1. Users compiling from the source tarball will need to apply the following diff: r1581.
Linux and Mac users are unaffected.
