[tor-relays] PSA: Exit nodes on 0.4.7.x might see less traffic

[Georg Koppen]

Hello everyone!

As you might have noticed, Tor Browser 13 got released last week[1] 
which ships for the first time a Tor 0.4.8.x version (0.4.8.7) to our 
stable Tor Browser users. One of the main features in the 0.4.8.x series 
is Conflux, which allows traffic-splitting to improve Tor performance.[2]

Given that we assume Tor Browser users are a large fraction of our 
overall Tor users and 0.4.8.7 deployed by Tor Browser results in 
pre-built Conflux circuits, there is a chance that exit nodes on 0.4.7.x 
might see less traffic over time. An easy way to avoid or fix that 
problem is an upgrade to the 0.4.8.x series.

Georg
