The older 909 bin was giving quite a few peeps tons of trouble, seems if you had to reboot your system while having the 909 on there it would not reconnect to the correct ip.
The newer 101216 solves this problem and allows the correct conection again.
You could theoretically still run with the older 909 but like I said if you reboot you may be forced to upgrade to 101216.
Take Care
