We have declared end-of-life for Tor 0.2.0.x. Those Tor versions have
several known flaws, and nobody should be using them. You should upgrade.

Specifically, the big flaw in Tor <= 0.2.0.35 is that its list of
directory authorities is out of date, so you’ll find it hard to learn
about the network. We’re signing the network status consensus with the
old signatures for now, but we’re going to stop doing that in a few weeks,
which means your Tor 0.2.0.x will fail to find the current network.

The only exception is people using Debian Lenny — our nice Debian
packager is trying to keep that package maintained for you.

As a bonus, if you move to a newer Tor you’ll get significant performance
boosts as a client, and you’ll improve the performance for others as
a relay.

Thanks,
