The current stable version of the code is C9400.  Get it here.

The current beta version, C96b5, is well tested but it is still in the experimental stages.  It is available here.  The previous beta, C96b4, is here.

Old versions of the code are accessed from this page.  These are kept as a record of the results obtained by the code in the past.  They are also an impressive demonstration of how much faster computers become every year.  Each of these versions took about a minute to calculate a complete planetary nebula model when it was the stable version.  (The current stable version does too).   But on today's computers the older versions can do a calculation in surprisingly short times.  The current version is not wasting time - it is just doing a far better representation of the physics.

The bleeding edge version is a very recent build that is in an undefined state.  Physical processes may be disabled, spectacular bugs could be present, or massive amounts of print may be generated.  It is described here.
