The changes are in
https://trac.torproject.org/projects/tor/ticket/11149
which is merged to git master and will be out in Tor 0.2.5.4-alpha.

So only when a majority of directory authorities are running with that
patch will the 0.2.2.x relays be cut out of the network.

But it's actually more subtle than that -- it's more accurately described
as "only when 5 or more directory authorities are online and not running
the patch will those relays be published".

https://consensus-health.torproject.org/ indicates that three authorities
are running the patch, so six aren't. If two of those six went offline,
that's enough for the remaining authorities to not put together a majority
of Running votes for the 0.2.2.x relays. It happens that two of those six
(turtles and dannenberg) *did* go offline while they were waiting to do
the openssl bug cleanup.
