Xatrix' Ryan "Ridah" Feltrin updated his .plan with this bit of news for Linux Kingpin server admins, as well as word that the Kingpin patch has entered final testing:

UPDATE: Server ops, the below binaries will not be compatible with current win32 clients. So best wait until the patch has been released (which will be simultaneous win32/linux) before upgrading your binaries.

The patch is undergoing final testing, and should be out soon.

The binaries in question are the Linux Kingpin clients released earlier today.
