　　改进列表

• 重要 bug 修复 (客户端，启动 ):

• Start making circuits as soon as DisabledNetwork is turned off.
  

• Resume expanding abbreviations for command-line options.
  

• Warn about attempts to run hidden services and relays in the same
       process: that's probably not a good idea.
  

• 重要 bug 修复(relay):

• Avoid queuing or sending destroy cells for circuit ID zero when we
       fail to send a CREATE cell.
  

• Fix ORPort reachability detection on relays running behind a
       proxy, by correctly updating the "local" mark on the controlling
       channel when changing the address of an or_connection_t after the
       handshake.
  

• 小特性 (bridge):

• Add an ExtORPortCookieAuthFileGroupReadable option to make the
       cookie file for the ExtORPort g+r by default.

• 小特性 (geoip):

• Update geoip and geoip6 to the August 7 2014 Maxmind GeoLite2
       Country database.

• 小的 bug 修复 (日志记录):

• Reduce the log severity of the "Pluggable transport proxy does not
       provide any needed transports and will not be launched." message,
       since Tor Browser includes several ClientTransportPlugin lines in
       its torrc-defaults file, leading every Tor Browser user who looks
       at her logs to see these notices and wonder if they're dangerous.
       Resolves bug 13124; bugfix on 0.2.5.3-alpha.

• Downgrade "Unexpected onionskin length after decryption" warning
       to a protocol-warn, since there's nothing relay operators can do
       about a client that sends them a malformed create cell. Resolves
       bug 12996; bugfix on 0.0.6rc1.

• Log more specific warnings when we get an ESTABLISH_RENDEZVOUS
       cell on a cannibalized or non-OR circuit. Resolves ticket 12997.

• When logging information about an EXTEND2 or EXTENDED2 cell, log
       their names correctly. Fixes part of bug 12700; bugfix
       on 0.2.4.8-alpha.

• When logging information about a relay cell whose command we don't
       recognize, log its command as an integer. Fixes part of bug 12700;
       bugfix on 0.2.1.10-alpha.

• Escape all strings from the directory connection before logging
       them. Fixes bug 13071; bugfix on 0.1.1.15. Patch from "teor".

• Minor bugfixes (controller):

• Restore the functionality of CookieAuthFileGroupReadable. Fixes
       bug 12864; bugfix on 0.2.5.1-alpha.

• Actually send TRANSPORT_LAUNCHED and HS_DESC events to
       controllers. Fixes bug 13085; bugfix on 0.2.5.1-alpha. Patch
       by "teor".

• Minor bugfixes (compilation):

• Fix compilation of test.h with MSVC. Patch from Gisle Vanem;
       bugfix on 0.2.5.5-alpha.

• Make the nmake make files work again. Fixes bug 13081. Bugfix on
       0.2.5.1-alpha. Patch from "NewEraCracker".

• In routerlist_assert_ok(), don't take the address of a
       routerinfo's cache_info member unless that routerinfo is non-NULL.
       Fixes bug 13096; bugfix on 0.1.1.9-alpha. Patch by "teor".

• Fix a large number of false positive warnings from the clang
       analyzer static analysis tool. This should make real warnings
       easier for clang analyzer to find. Patch from "teor". Closes
       ticket 13036.

• Distribution (systemd):

• Verify configuration file via ExecStartPre in the systemd unit
       file. Patch from intrigeri; resolves ticket 12730.

• Explicitly disable RunAsDaemon in the systemd unit file. Our
       current systemd unit uses "Type = simple", so systemd does not
       expect tor to fork. If the user has "RunAsDaemon 1" in their
       torrc, then things won't work as expected. This is e.g. the case
       on Debian (and derivatives), since there we pass "--defaults-torrc
       /usr/share/tor/tor-service-defaults-torrc" (that contains
       "RunAsDaemon 1") by default. Patch by intrigeri; resolves
       ticket 12731.

• Documentation:

• Adjust the URLs in the README to refer to the new locations of
       several documents on the website. Fixes bug 12830. Patch from
       Matt Pagan.

• Document 'reject6' and 'accept6' ExitPolicy entries. Resolves
       ticket 12878.

　　Tor 是一个帮助你抵御流量分析的软件项目， 流量分析是一种对网络的监视行为。Tor 将你的通信通过一个由遍及全球的志愿者运行的中继（relay）所组成的分布式网络转发， 以此来保护你的安全：它令监视你的 Internet 连接的那些人无法知道你所访问的站点， 它还令你所访问的站点无法知道你的物理位置。Tor 能与现有的许多应用程序配合工作， 包括 Web 浏览器、即时通讯客户端、远程登录和基于 TCP 协议的其他应用程序。
