Changes in version 0.2.9.4-alpha - 2016-10-17
Foo bar
Tor 0.2.9.4-alpha adds numerous small features and fix-ups to previous
versions of Tor, including the implementation of a feature to future-
proof the Tor ecosystem against protocol changes, some bug fixes
necessary for Tor Browser to use unix domain sockets correctly, and
several portability improvements. We anticipate that this will be the
last alpha in the Tor 0.2.9 series, and that the next release will be
a release candidate.
o Major features (subprotocol versions):
- 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.
- 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.

- Remove broken fallbacks from the hard-coded fallback directory list.

o Minor features (client, directory):
- Since authorities now omit all routers that lack the Running and Valid
flags, we assume that any relay listed in the consensus must
have those flags. Closes ticket 20001; implements part of proposal
272.

o Minor features (unix domain sockets):
- When configuring a unix domain socket for a SocksPort,
ControlPort, or Hidden service, you can now wrap the address
in quotes, using C-style escapes inside the quotes. This
allows unix domain socket paths to contain spaces.
o Minor features (geoip):
- Update geoip and geoip6 to the October 4 2016 Maxmind GeoLite2
Country database.

ControlPort, or Hidden service, you can now wrap the address in
quotes, using C-style escapes inside the quotes. This allows unix
domain socket paths to contain spaces.
o Minor features (virtual addresses):
- Increase the maximum number of bits for the IPv6 virtual network prefix
from 16 to 104. In this way, the condition for address allocation is less
restrictive.
Closes ticket 20151; feature on 0.2.4.7-alpha.

o Minor bugfixes (address discovery):
- Stop reordering IP addresses returned by the OS.
This makes is more likely that Tor will guess the same relay IP address every time.
Fixes issue 20163; bugfix on 0.2.7.1-alpha, ticket 17027.

o Documentation:
- Added module-level internal documentation for 36 C files that
previously didn't have a high-level overview.
o Required libraries:
- When building with OpenSSL, Tor now requires version 1.0.1 or later.
OpenSSL 1.0.0 and earlier are no longer supported by the OpenSSL team,
and should not be used. Closes ticket 20303.
