LIGGGHTS 2.0.2: (released 06 July 2012)

+ Added a check to fix property/global for style 'atomtypepair' that checks if the values are symmetric. Note that now style 'matrix' is not necessarliy symmetric, but 'atomtypepair' is.
+ Fixed a bug in random number generation for parallel cases when fix insert/rate/region or fix insert/pack were used. Thanks to Chris Stoltz (P&G) for sending a test case.
+ Added some new option 'random_distribute'='exact' to all the fix insert/* commands (which is now default). This allows to match the requested # of particles to be inserted at each insertion step more exactly, but introduces some small MPI overhead. Option 'random_distribute'='uncorrelated' will reporduce the way things worked in LIGGGHTS 2.0 and 2.0.1.
+ Fixed an issue with unfixing multiple fix move/mesh commands which operate on different meshes. Thanks to Joe Satch and Peter Falkingham (Royal Veterinary College, University of London) for posting a cases that showed this issue
+ Fixed a bug with pair gran/hooke/history/stiffness where LIGGGHTS would exit with a segfault afer finishing the simuation. Thanks again to Joe Satch for letting us know.
+ Fixed some more minor machine-dependant compilation issues and typos in the doc. Thanks to Stefan Amberger (JKU) for the notes.
+ Fixed a formatting issue in the fix mesh/surface doc. Thanks to Andreas Aigner (JKU) for the note.
+ Applied a whitespace patch that should help making LIGGGHTS code more readable. Thanks to Steve Plimpton, Paul Crozier (both Sandia) and Axel Kohlmeyer (Temple) for collaboration on that subject.
+ Fixed a small bug in fix transportequation/scalar that would only arise if that fixed is used for other purpose than for heattransfer.

However, there are some restrictions in 2.0.2 (see below) which will be relaxed over time:
+ region tetmesh is not yet available
+ fix mesh/gran/stressanalysis is not yet available
+ 'all_in yes' is not yet available for fix insert/stream
+ fix breakparticle/force is not yet available
