Changes in version 0.2.8.1-alpha - 2016-02-0?
|
||||
XXXX Blurb goes here XXXX
|
||||
|
||||
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 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 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

||||
some low ports have been configured. You can change this behavior
|
||||
with the new option KeepBindCapabilities. Closes ticket 8195.
|
||||
|
||||
o Major features (consensus downloads):
|
||||
o Major features (directory system):
|
||||
- Schedule multiple in-progress consensus downloads during client
|
||||
bootstrap. Use the first one that starts downloading, close the
|
||||
rest. This reduces failures when authorities are slow or down.

to fallback churn. Implements ticket 4483 (reduce failures when
|
||||
authorities are down). Patch by "teor". Implements IPv4 portions
|
||||
of proposal 210 by "mikeperry" and "teor".
|
||||
|
||||
o Major features (directory mirrors):
|
||||
- Include an opt-in trial list of default fallback directories in
|
||||
add_default_fallback_dir_servers(). Doing this should improve
|
||||
client reliability and initial bootstrap performance, and reduce
|
||||
load on the directory authorities. Closes ticket 15775. Patch by
|
||||
"teor". OnionOO script by "weasel", "teor", "gsathya",
|
||||
and "karsten".
|
||||
|
||||
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 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

|
||||
the state for the largest algorithm would need. This change saves
|
||||
up to 672 bytes per circuit. Closes ticket 17796.
|

- Improve performance when hashing non-multiple of 8 sized buffers,

based on Andrew Moon's Public Domain SipHash-2-4 implementation.
