Changes in version 0.2.8.1-alpha - 2016-02-0?
XXXX Blurb goes here XXXX
o Removed features:
- Remove client-side support for connecting to Tor servers running
versions of Tor before 0.2.3.6-alpha. These servers didn't support
the v3 TLS handshake protocol, and are no longer allowed on the
Tor network. Implements the client side of ticket 11150. Based on
patches by Tom van der Woerdt.
o Major key updates:
- Update the V3 identity key for dannenberg: it was changed on 18
November 2015. Closes task 17906. Patch by "teor".
o Major features (security, Linux):
- When Tor is started as root on Linux and told to switch user ID,
it can now retain the capabilitity to bind to low ports. By
default, Tor will do this only when it's switching user ID and
some low ports have been configured. You can change this behavior
with the new option KeepBindCapabilities. Closes ticket 8195.
o Major features (consensus downloads):
- Schedule multiple in-progress consensus downloads during client

with the new option KeepBindCapabilities. Closes ticket 8195.
o Major features (directory system):
- Previously only relays who explicitly opened a directory port
(DirPort) accepted directory requests from clients. Now all
relays, with and without a DirPort, who do not disable the
DirCache option accept and serve directory requests sent
(tunnelled) through their ORPort. Closes ticket 12538.
o Minor features (security, RNG):
- Adjust Tor's use of OpenSSL's RNG APIs so that they absolutely,
positively are not allowed to fail. Previously we depended on
internals about OpenSSL behavior. Closes ticket 17686.
- Never use the system entropy output directly for anything besides
seeding the PRNG. When we want to generate important keys, instead
of using system entropy directly, hash it with the PRNG stream.
This may help resist certain attacks based on broken OS entropy
implementations. Closes part of ticket 17694.
- Use modern system calls to generate strong entropy on platforms
that provide them. Closes ticket 13696.
o Major key updates:
- Update the V3 identity key for dannenberg: it was changed on 18
November 2015. Closes task 17906. Patch by "teor".
o Minor features (security, clock):
- Warn when the system clock is set back in time (when the state
file was last written in the future). Tor doesn't know that
consensuses have expired if the clock is in the past. Patch by
"teor". Implements ticket 17188.
o Minor features (security, exit policies):
- ExitPolicyRejectPrivate rejects more private addresses by default.
Specifically, it rejects the relay's outbound bind addresses (if
configured), and the relay's configured port addresses (such as
ORPort and DirPort). Fixes bug 17027; bugfix on 0.2.0.11-alpha.
Patch by "teor".

o Minor features (security, clock):
- Warn when the system clock is set back in time (when the state
file was last written in the future). Tor doesn't know that
consensuses have expired if the clock is in the past. Patch by
"teor". Implements ticket 17188.
o Minor features (crypto):
- Add SHA512 support to crypto.c. Closes ticket 17663; patch from
George Tankersley.
- Add SHA3 and SHAKE support to crypto.c. Closes ticket 17783.
- When allocating a digest state object, allocate no more space than
we actually need. Previously, we were allocating as much space as
the state for the largest algorithm would need. This change saves
up to 672 bytes per circuit. Closes ticket 17796.
o Minor features (directory downloads):
- Wait for busy authorities and fallbacks to become non-busy when
bootstrapping. (A similar change was made in 6c443e987d for
directory servers chosen from the consensus.) Closes ticket 17864;
patch by "teor".
- Add UseDefaultFallbackDirs, which enables any hard-coded fallback
directory mirrors. Default is 1, set it to 0 to disable fallbacks.
Implements ticket 17576. Patch by "teor".
o Minor features (IPv6):
- Add a flag ipv6=address:orport to the DirAuthority and FallbackDir
torrc options. Add hard-coded ipv6 addresses for directory
authorities with ipv6 lines in their descriptors. Closes ticket
17327; patch from Nick Mathewson / "teor".
- Add address policy assume_action support for IPv6 addresses.
- Limit IPv6 mask bits to 128.
- Warn when comparing against an AF_UNSPEC address in a policy, it's
almost always a bug. Closes ticket 17863; patch by "teor".
- Allow users to configure directory authorities and fallback
directory servers with IPv6 addresses and ORPorts. Resolves
ticket 6027.
- routerset_parse now accepts IPv6 literal addresses. Fixes bug
17060; bugfix on 0.2.1.3-alpha. Patch by "teor".
- Make tor_ersatz_socketpair work on IPv6-only systems. Fixes bug
17638; bugfix on 0.0.2pre8. Patch by "teor".
o Minor features (logging):
- When logging to syslog, allow a tag to be added to the syslog
identity (the string prepended to every log message).
The tag can be configured with SyslogIdentityTag and
defaults to none. Setting it to "foo" will cause logs to be tagged
as "Tor-foo". Closes ticket 17194.
