[lammps-users] What changes has been made in Nose-Hoover intergrators on April-7-2010?

If you're saying that you had problems running something
with a 4-year old version of the code, and don't have problems
with the current version, then yes that is possible, for any
number of reasons, including an improved Nose/Hoover

Why not just use the current version and be happy?
