3.2 x 4.0 beta

Quote :

- Prior to installing CCS4 Preview you need to uninstall a previous version
of
CCS (3.x), as both versions cannot be installed at the same time.
This means that you may want to put some time aside exclusively for
reviewing
CCS4, then reinstall CCS 3.2 back. (unless you can dedicate a separate
machine
for CCS4)
