I got the message "Please upgrade! This version of Tor (#.#.#.#) is not recommended, according to the directory authorities. Recommended versions are..."
So I ran
apt-get update && apt-get upgrade (I'll have to look into unattended upgrades someday) and my tor relay got upgraded to 0.2.9.14 but it seems 0.3.1.9 is already released. Why wasn't I upgraded to 0.3.1.9?
Is there just a delay before it gets to Debian repositories? It just seems really far behind.
I'm running Raspbian Stretch Lite on a Raspberry Pi 3.
Update, I can see from Debian's package search that I have the latest version for Debian Stretch.
I'm still feeling outdated though. I want my relay to be better than everyone else's! :P
