LIGGGHTS 2.0 RC: (released 15 June 2012)

Major feature upgrades include:
+ Merged in more than 2 years of LAMMPS updates & patches (since 10 March 2010), see http://lammps.sandia.gov/bug.html
+ New syntax for many commands, yielding a hopefully clearer input script. For details, see doc/liggghts_2.X_tutorial.html in the LIGGGHTS tarball
+ All-new mesh implementation, featuring:
+ + modular mesh design using property storage class
+ + fix mesh is now faster due to reworks in mesh topology
+ + fix mesh contains a new optimzed particle-mesh distance algorithm by Philippe Seil (JKU)
+ + mesh operations and moving mesh operations are more efficient as well
+ + it is now possible to superpose multiple fix move/mesh commands
+ particle insertion via the family of fix insert commands is now fully parallel, overlapcheck will scale in parallel

Further feature upgrades include:
+ thermo output now supports Cundall Number (thermo_custom keyword cu)
+ added a new dump decomposition/vtk command to dump the processor decompoistion for parallel runs into VTK files
+ doc/Manual.pdf is now always up-to-date with every release

Fixed a number of bugs:
+ some bugfixes related to fix property/atom
+ fixed a bug when using fix insert commands in parallel with keyword 'volume_fraction_region'

However, there are some restrictions in 2.0RC which will (see below) which will be relaxed later:
+ region tetmesh is not yet available
+ fix mesh/gran/stressanalysis is not yet available
+ restart functionality for fix mesh is not yet available
+ 'all_in yes' is not yet available for fix insert/stream
+ fix breakparticle/force is not yet available

We now ported to Github, meaning the location of the GIT server has changed for the LIGGGHTS 2.X branch. For info how to access it, see here.
