I tried to get bind 9.4.0 beta sources, but i couldn't find them here:
ftp://ftp.isc.org/isc/bind9/

I must be looking in the wrong place. Basically i am eager to learn about 
the changes compared to 9.3.1 and hoped to test it out already.
Especially the increase in performance interests me.
Any hints where i can download the source?
Bye,
