[network-health] Your Tor bridge is running an obsolete version

[Philipp Winter]

Hi there,

You seem to be running the following Tor bridge, which is great:

  B9FAEC491A4BDA3064758272B32E4771F48FC4E4

But that Tor version (0.4.0.5) is obsolete, and because of old bugs,
we will soon cut bridges running those versions out of the network.
Please consider upgrading!

You can find Tor packages and instructions for your distro / OS here:
<https://community.torproject.org/relay/setup/bridge/>

Ideally you will switch to keeping up with our stable releases, but if
you need a stable that is especially stable, the Tor 0.3.5 branch will
be maintained until Feb 2022:
<https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTorReleases#Current>
and you can see the lifetimes of other Tor versions on that table too.

Let us know if we can do anything to make the process easier.

And lastly, I am copying the new network health mailing list (which has
public archives), to help us stay synced:
<https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkHealthTeam>

Thanks,
Philipp
