Previously, versions of Tor looked at the declared Tor + version of a relay to tell whether they could use a given feature. + Now, they should be able to rely on its declared subprotocol versions. + This change allows compatible implementations of the Tor protocol(s) to + exist without declaring compatibility with pretending to be particular + releases of Tor itself. Closes ticket 19958; implements part of + proposal 264. + + - Tor directory authorities now vote on a set of recommended subprotocol + versions, and on a set of required subprotocol versions. Clients and + relays that lack support for a _required_ suprotocol version will not + start; those that lack support for a _recommended_ subprotocol version + will warn the user to upgrade.
