+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 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.
+
+ 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
+ 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 (command-line interface):
+ - Make --hash-password imply --hush to prevent unnecessary noise. Closes
+ ticket 15542.
+
+ 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 (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 (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,
+ attempt to have the kernel deliver a SIGTERM on tor exit if
+ the pluggable transport process is still running. Resolves
+ ticket 15471.
+
+
+ o Minor features (testing):
+ - Add make rule `check-changes` to verify the format of changes files.
+ Closes ticket 15180.
+ - Add unit tests for control_event_is_interesting().
+ Add a compile-time check that the number of events doesn't exceed
+ the capacity of control_event_t.event_mask.
+ Closes ticket 15431, checks for bugs similar to 13085.
+ Patch by "teor".
+ - Commandline argument tests moved to Stem. Resolves ticket 14806.
+ - Integrate the ntor, backtrace and zero lengths keys tests into the
+ automake test suite. Closes ticket 15344.
+ - Remove assertions during builds to determine Tor's test coverage.
+ We don't want to trigger these even in assertions, so including
+ them artificially makes our branch coverage look worse than it is.
+ This patch provides the new test-stem-full and coverage-html-full
+ configure options. Implements ticket 15400.
+ - Add a test to verify that the compiler does not eliminate our
+ memwipe() implementation. Closes ticket 15377.
+
+ 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 (command-line interface):
+ - 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 (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 (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 bugfixes (statistics):
+ - Disregard the ConnDirectionStatistics torrc options when Tor is
+ not a relay since in that mode of operation no sensible data is
+ being collected and because Tor might run into measurement hiccups
+ when running as a client for some time, then becoming a relay. Fixes
+ bug 15604; bugfix on 0.2.2.35.
+
+ o Minor bugfixes (build):
+ - Improve out-of-tree builds by making non-standard rules work and clean up
+ additional files and directories. Fixes bug 15053; bugfix on
+ 0.2.7.0-alpha.
+
+ o Minor bugfixes (command-line interface):
+ - When "--quiet" is provided along with "--validate-config", do not
+ write anything to stdout on success. Fixes bug 14994; bugfix on
+ 0.2.3.3-alpha.
+ - When complaining about bad arguments to "--dump-config", use
+ stderr, not stdout.
+
+ o Minor bugfixes (configuration, unit tests):
+ - Only add the default fallback directories when the DirAuthorities,
+ AlternateDirAuthority, and FallbackDir directory config options
+ are set to their defaults.
+ The default fallback directory list is currently empty, this fix
+ will only change tor's behaviour when it has default fallback
+ directories.
+ Includes unit tests for consider_adding_dir_servers().
+ Fixes bug 15642; bugfix on 90f6071d8dc0 in 0.2.4.7-alpha.
+ Patch by "teor".
+
+ o Minor bugfixes (hidden service):
+ - Remove an extraneous newline character from the end of hidden
+ service descriptors. Fixes bug 15296; bugfix on 0.2.0.10-alpha.
+
+ o Minor bugfixes (interface):
+ - Print usage information for --dump-config when it is used without
+ an argument. Also, fix the error message to use different wording
+ and add newline at the end. Fixes bug 15541; bugfix on 0.2.5.1-alpha.
+
+ o Minor bugfixes (logs):
+ - When building Tor under Clang, do not include an extra set of
+ parentheses in log messages that include function names.
+ Fixes bug 15269; bugfix on every released version of Tor when
+ compiled with recent enough Clang.
+
+ o Minor bugfixes (test networks)
+ - When self-testing reachability, use ExtendAllowPrivateAddresses
+ to determine if local/private addresses imply reachability.
+ The previous fix used TestingTorNetwork, which implies
+ ExtendAllowPrivateAddresses, but this excluded rare configs where
+ ExtendAllowPrivateAddresses is set but TestingTorNetwork is not.
+ Fixes bug 15771; bugfix on 0.2.6.1-alpha.
+ Patch by "teor", issue discovered by CJ Ess.
+
+ o Minor bugfixes (testing):
+ - Set the severity correctly when testing get_interface_addresses_ifaddrs()
+ and get_interface_addresses_win32(), so that the tests fail gracefully
+ instead of triggering an assertion. Fixes bug 15759; bugfix on
+ 0.2.6.3-alpha. Reported by Nicolas Derive.
+ - Check for matching value in server response in ntor_ref.py.
+ Fixes bug 15591; bugfix on 0.2.4.8-alpha. Reported and fixed
+ by "joelanders".
+
+ o Minor bugfixes (correctness):
+ - Remove side-effects from tor_assert() calls. This was harmless,
+ because we never disable assertions, but it is bad style and
+ unnecessary. Fixes bug 15211; bugfix on 0.2.5.5, 0.2.2.36, and
+ 0.2.0.10.
+ - For correctness, avoid modifying a constant string in
+ handle_control_postdescriptor. Fixes bug 15546; bugfix on
+ 0.1.1.16-rc.
+
+ o Minor bugfixes (network):
+ - When attempting to use fallback technique for network interface
+ lookup, disregard loopback and multicast addresses since they are
+ unsuitable for public communications.
+
+ o Code simplification and refactoring:
+ - Move the hacky fallback code out of get_interface_address6()
+ into separate function and get it covered with unit-tests. Resolves
+ ticket 14710.
+ - Refactor hidden service client-side cache lookup to intelligently
+ report its various failure cases, and disentangle failure cases
+ involving a lack of introduction points. Closes ticket 14391.
+ - Use our own Base64 encoder instead of OpenSSL's, to allow more control
+ over the output. Part of ticket 15652.
+
+ o Removed code:
+ - Remove `USE_OPENSSL_BASE64` and the corresponding fallback code and
+ always use the internal Base64 decoder. The internal decoder has been
+ part of tor since tor-0.2.0.10-alpha, and no one should be using the
+ OpenSSL one. Part of ticket 15652.
+
+ o Documentation:
+ - Improve the descriptions of statistics-related torrc options in
+ the manpage to describe rationale and possible uses cases. Fixes
+ issue 15550.
+ - Improve the layout and formatting of ./configure --help messages.
+ Closes ticket 15024. Patch from "cypherpunks".
+ - Standardize on the term "server descriptor" in the manual page.
+ Previously, we had used "router descriptor", "server descriptor",
+ and "relay descriptor" interchangeably. Part of ticket 14987.
+
+ 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 Removed code:
+ - Remove the 'tor_strclear()' function; use memwipe() instead.
+ Closes ticket 14922.
+
+ o Removed features:
+ - Remove the (seldom-used) DynamicDHGroups feature. For
+ anti-fingerprinting we now recommend pluggable transports; for
+ forward-secrecy in TLS, we now use the P-256 group.
+ Closes ticket 13736.
+ - Remove the undocumented "--digests" command-line option. It
+ complicated our build process, caused subtle build issues
+ on multiple platforms, and is now redundant since we started
+ including git version identifiers. Closes ticket 14742.
+ - Tor no longer contains workarounds for stat files generated by
+ super-old versions of Tor that didn't choose guards sensibly.
+ - Tor no longer contains checks for ancient directory cache versions
+ that didn't know about microdescriptors.
