Changes in version 0.2.7.1-alpha - 2015-05-??
Tor 0.2.7.1-alpha is the first alpha release in its series.
+ o New system requirements:
+ - Tor no longer includes workarounds for Libevent versions before
+ 1.3e. Libevent 2.0 or later is recommended. Closes ticket 15248.
+
o Major features (controller):
- Add the ADD_ONION and DEL_ONION commands that allows the creation
and management of hidden services via the controller. Closes
ticket 6411.
- New "GETINFO onions/current" and "GETINFO onions/detached" to get
- information about hidden services created via the controller.
- Part of ticket 6411.
- - New HSFETCH command to launch a request for a hidden service descriptor.
- Closes ticket 14847.
+ information about hidden services created via the controller. Part
+ of ticket 6411.
+ - New HSFETCH command to launch a request for a hidden service
+ descriptor. Closes ticket 14847.
o Major bugfixes (hidden services):
- - Revert commit that made directory authority assign the HSDir flag to
- relay without a DirPort which is bad because relay can't handle
+ - Revert commit that made directory authority assign the HSDir flag
+ to relay without a DirPort which is bad because relay can't handle
BEGIN_DIR cells. Fixes bug 15850; bugfix on tor-0.2.6.3-alpha.
- o Minor features (HS popularity countermeasure):
- - To avoid leaking HS popularity, don't cycle the introduction point
- when we've handled a fixed number of INTRODUCE2 cells but instead
- cycle it when a random value of introductions is reached thus making
- it more difficult for an attacker to find out the amount of clients
- that has passed through the introduction point for a specific HS.
- Closes ticket 15745.
+ o Minor features (clock-jump tolerance):
+ - Recover better when our clock jumps back many hours, like might
+ happen for Tails or Whonix users who start with a very wrong
+ hardware clock, use Tor to discover a more accurate time, and then
+ fix their clock. Resolves part of ticket 8766. [I'd call this a
+ major feature if it actually fixed all of the issues.]
o Minor features (command-line interface):
- - Make --hash-password imply --hush to prevent unnecessary noise. Closes
- ticket 15542.
+ - Make --hash-password imply --hush to prevent unnecessary noise.
+ Closes ticket 15542.
+ - Print a warning whenever we find a relative file path being used
+ as torrc option. Resolves issue 14018.
+ - The "--hash-password" option now implies "--hush" to avoid
+ needless noise. Closes ticket 15542. Patch from "cypherpunks".
+
+ o Minor features (controller):
+ - Controllers can now use GETINFO hs/client/desc/id/... to retrieve
+ items from the client's hidden service descriptor cache. Closes
+ ticket 14845.
- o Minor features (controller)
- - Controllers can now use GETINFO hs/client/desc/id/... to
- retrieve items from the client's hidden service descriptor
- cache. Closes ticket 14845.
+ o Minor features (controller):
+ - Add DirAuthority lines for default directory authorities to output
+ of the GETINFO config/defaults controller command if not already
+ present. Implements ticket 14840.
+ - Implement a new controller command "status/fresh-relay-descs" to
+ fetch a descriptor/extrainfo pair that was generated on demand
+ just for the controller's use. Implements ticket 14784.
o Minor features (DoS-resistance):
- Make it harder for attackers to overwhelm hidden services with
introductions, by blocking multiple introduction requests on the
same circuit. Resolves ticket 15515.
+ o Minor features (geoip):
+ - Update geoip to the April 8 2015 Maxmind GeoLite2 Country database.
+ - Update geoip6 to the April 8 2015 Maxmind GeoLite2
+ Country database.
+
+ o Minor features (HS popularity countermeasure):
+ - To avoid leaking HS popularity, don't cycle the introduction point

+ cycle it when a random value of introductions is reached thus
+ making it more difficult for an attacker to find out the amount of
+ clients that has passed through the introduction point for a
+ specific HS. Closes ticket 15745.
+
o Minor features (logging):
- Include the Tor version in all LD_BUG log messages, since people
tend to cut and paste those into the bugtracker. Implements
ticket 15026.
o Minor features (pluggable transports):
- - When launching managed pluggable transports, setup a valid open stdin
- in the child process that can be used to detect if tor has terminated.
- The "TOR_PT_EXIT_ON_STDIN_CLOSE" enviornment variable can be used by
- implementations to detect this new behavior. Resolves ticket 15435.

- When launching managed pluggable transports on linux systems,

- the pluggable transport process is still running. Resolves

- - Add unit tests for control_event_is_interesting().
- Add a compile-time check that the number of events doesn't exceed
