LIGGGHTS 2.3.7: (released 6 September 2013)
+ Added a warning message to prompt the user to use "neigh_modify delay 0" with granular pair styles.
+ Fixed some bugs in fix massflow/mesh which could lead to a crash; thanks to Rouven Weiler (BASF) and Stefan Radl (TU Graz) for noting/fixing this.
+ Fixed a sign bug in fix mesh/surface/stress/servo. Thanks to Andreas Aigner (JKU) for fixing this.
+ Fixed an issue where the new epsd2 rolling friction model requested the user to define a viscousdampingratio, which was not used and needed by the model. Thanks to Christian Richter (University of Magdeburg) for noting this.
+ Fixed an issue where the #particles to insert for the "volumefraction" option combined with "all_in yes" of fix insert/pack was not correctly calculated in case the particle radius was in the same order of magnitude than the length of the insertion volume. Thanks to Paul Winkler (University of Weimar) for noting this.
+ Fixed a a communication bug in the ellipsoidal particle implementation which could lead to a crash. Thanks to Daniel Queteschiner (JKU) for fixing this.
+ Fixed an issue with fix transportequation/scalar that could lead to the fix ignoring very small initial values for the stored property in some cases. Thanks to Josef Kerbl (DCS Computing) for finding and fixing this.
+ Fixed a problem where restarting simulations using the Finnie wear model was not possible. Thanks to Kirk Fraser (Roche) for posting a testcase.
+ Andreas Eitzlmayr (TU Graz) added new options to compute reduce for SPH and fixed a bug in his new functionality in fix ave/spatial.
+ Included some LAMMPS patches for pair hybrid/overlay. Thanks to Evan Smuts (U Cape Town) for merging these in.
However, there are some restrictions in 2.3.7 (see below) which will be relaxed over time:
+ fix breakparticle/force is not yet available
