[tor-relays] Keeping your obfsproxy up to date

Hi list, I just found out that my obfsproxy relays didn't obfsproxy any more. I was apparently running a pretty old version, installed from source. How do you people keep your obfsproxies (and pyptlib) up to date? Are there packages? Is there a list or some other channel where new versions are announced that I'm not paying attention to? Thanks, Linus
