Can you give us some idea on what might not be working in this initial build? I would rater not go into this blindly. My wife would not be happy if I screw up our brand new router because of my incessant hacking. :) Thanks!
You can simply go through these discussions to know about the bugs of this firmware.
Yup, now you have the provision to use others experience and keep your router far from those bugs.
Don't forget to share your experience too, it will be helpful for the community if you add some more.
