Changes in version 0.2.9.4-alpha - 2016-10-17
Foo bar
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.
o Minor feature (fallback directories):
- Remove broken fallbacks from the hard-coded fallback directory list.
Closes ticket 20190; patch by teor.
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 (compilation, portability):
- Tor now compiles correctly on MacOS 10.12 (aka "Sierra"). Closes
ticket 20241.
o Minor features (development tools, etags):
- Teach the "make tags" Makefile target how to correctly find
"MOCK_IMPL" function definitions. Patch from nherring; closes
ticket 16869.
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.
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.
Reported by René Mayrhofer, patch by "cypherpunks".
o Minor bugfixes (client, unix domain sockets):
- Disable IsolateClientAddr when using AF_UNIX backed SocksPorts
as the client address is meaningless. Fixes bug 20261; bugfix on
0.2.6.3-alpha.
o Minor bugfixes (compilation, OpenBSD):
- Detect Libevent2 functions correctly on systems that provide
libevent2, but where libevent1 is linked with -levent. Fixes bug
19904; bugfix on 0.2.2.24-alpha. Patch from Rubiate.
o Minor bugfixes (configuration):
- When parsing quoted configuration values from the torrc file,
handle windows line endings correctly. Fixes bug 19167; bugfix on
0.2.0.16-alpha. Patch from "Pingl".
o Minor bugfixes (getpass):
- Defensively fix a non-triggerable heap corruption at do_getpass() tow
protect ourselves from mistakes in the future. Fixes bug #19223; bugfix
on 0.2.7.3-rc. Bug found by Guido Vranken, patch by nherring.
o Minor bugfixes (hidden service):
- Allow hidden services to run on IPv6 addresses even when the
IPv6Exit option is not set. Fixes bug 18357; bugfix on
0.2.4.7-alpha.
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.
Changes in version 0.2.9.3-alpha - 2016-09-23
