o Major features (subprotocol versions):
|
|
|
|
- Tor now uses "subprotocol versions" to indicate
|
|
compatibility. 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. Closes ticket 19958; implements part of
|
|
proposal 264.
