released 30 June 2011

The Geant4 development source code is freely available. See the licence conditions.

Feedback for any problem found is welcome via the usual support channels.

Since this is beta software, please consider that:

It is distributed "as is", and full support cannot be provided
Some code may be new or enhanced, therefore still experimental and not fully tested
