 The release series 0.3.0 through 0.3.4 are no longer supported, and we
 have encountered at least one bug (#27841)  caused by them lingering on
 the network.

 We should have the authorities stop listing them in their votes.  The
 patch here is simple enough -- we just edit dirserv_get_status_impl to
 reject everything newer than "0.3.0.0" and less new than "0.3.5.x" (for
 some well chosen "x").

 But before we do this, we should take necessary steps to contact operators
 and let them know that they really really need to upgrade.
