Comment (by arma):

 Ok, we fucked this one up by ignoring it and then waiting for the patch to
 be perfect.

 In the mean time, time has moved on, and now there remain only 7 relays
 running the broken versions:

 I've reached out to 6 of the 7 of them, to get them to upgrade. Alas, the
 only one with no ContactInfo is also the only the one with the Guard flag.
 But I think our next step here is either to change the directory
 authorities to reject relays running the buggy versions, or to close this
 ticket and pretend it doesn't matter anymore.
