LIGGGHTS 2.0.7: (released 23 August 2012)

+ Added a fix ave/euler/stress that calculates the correct stress for dense granular system and averages it over a Eulerian Grid (compute stress/atom neglects the contribution of the average velocity in the molecular diffusion term of the stress tensor). Also added a dump euler/vtk to dump the stress to VTK files. Thanks to Simon Schneiderbauer (JKU) for helpful discussions and to Andreas Aigner (JKU) for bugfixes and for adding code to make this feature work for triclinic boxes.
+ Added a new "verbose" option to all the fix insert commands to turn off printing info about inserted particles during a run that can potentially make thermo output unreadable.
+ Added a new "output" option to dump mesh/VTK command to output per-face values in an interpolated manner. Thanks to Felix Kleinfeldt and Christian Richter (both OVGU Magdeburg) for this contribution.
+ Fixed a small issue with how fix insert/rate/region was parsing args where wrong command syntax could result in mis-leading error messages.
+ Corrected the fix heat/gran doc with respect to the area_correction flag. Thanks to Moritz Höfert (BASF) for the note.
+ Fixed a bug where particle-triangle interactions were not calculated correctly for some cases where the triangle hs obtuse angles. Thanks to Chris Stoltz (P&G) for a test case and to Philippe Seil for help with fixing this.
+ Added fixgroup support for fix wall/gran/*. Now the wall is only applied to particles in the fix group. Thanks to Tap Sab and Mark Bentley (Space Reseach Institute, ÖAW) for noting that this was missing.
+ Re-added some missing part in compute wall/gran/local where the triangle ID was always zero in the output. Thanks again to Mark Bentley (Space Reseach Institute, ÖAW) for the note.

However, there are some restrictions in 2.0.7 (see below) which will be relaxed over time:
+ region tetmesh is not yet available
+ 'all_in yes' is not yet available for fix insert/stream
+ fix breakparticle/force is not yet available
