Current IntegraMOD Version on Site

I am confused regarding the policy of this new site. With all due respect, I thought that part of the issue with the old site was the use of a non-stock IM version being used on the IM core site. What you saw was not necessarily what you got when you downloaded the latest stable release. I understand this site is running a beta version of 1.4.1 which is not even available for general downloading. Will this continue to be the policy of the new admins - to run the core site on beta versions of forthcoming public releases? Is this a good policy, especially with regard to troubleshooting and comparison to our own installations?
