Hello!
To repeat what recently[1] got brought up: it's time to get relays upgraded in case they are running the EOL 0.4.6.x Tor series. We'll start reaching out to operators with valid contact information this week and plan to reject relays which are still on 0.4.6.x in about 5 weeks from now on at the end of September. You can follow along that process in our bug tracker[2] if you want.
For the general processes around dealing with EOL relays in the Tor network see my mail from last October[3].
Feedback and improvements are welcome, as always.
Georg
