Relase estimation for version 4?

Hi, is there any estimation for a release date for the version 4 of FR? We would like to see the TACACS feature in the software. Then we could suggest my customer to switch from a commercial RADIUS server to FR. I assume that networkradius also will support the new features of version 4.
