Hello Delton,

you will need to wait till tor- becomes stable if you want to
use scramblesuit with a stable Tor. Till then, please keep on using
Tor nightlies.

As far as your second question goes, unfortunately we don't have good
upgrade processes yet. I suggest you do 'apt-get upgrade' every once
in a while to get the latest nightlies of obfsproxy/tor. If there are
any urgent upgrades that you need to perform I will send an email to

Feel free to ask any other questions you have.
