SW2 and SW1 status

Hi all, I'm experiencing for three months instability problems with Squeak 3.8/latest release, and since I'm unable and don't have time to track down the problems, I suggest to downgrade the squeakmap release. It should be wise to offer as the latest release a stable release and to stick to that. But it seems that the automatic script don't care about the stable/unstable squeakmap system, it seems that the script loads the latest release regardless of the stability status. So I will probably delete the latest release on squeakmap, and keep it for record on squeaksource. I would like also to know if it is now possible to use SW2 ? Thanks Samir
