We followed the first couple of Kingpin beta releases here, but a huge red banner has since been added to the page with a request from Ridah not to, so if you want to stay current with the doings over there between official releases, feel free, but the updates will no longer be posted here. Here is what Ridah's note says:

"Please do not link, mirror or post new release announcements for the files on this page.
Updates are likely to occur on a regular (daily) basis, announcing new releases will no doubt prove to be overkill.
Thank you for your co-operation."
