happyhere:

anyone here have tried this newer firmware?  it is not yet showing in router's auto update firmware page.

GreenBay42:
Correct. This is still considered a BETA firmware which is not pushed through the auto update server.

I haven't heard of any issues with the beta. If it doesn't work you can always downgrade back to the older version.
