-Changes in version 0.3.3.6 - 2018-05-22
-  Tor 0.3.3.6 is the first stable release in the 0.3.3 series. It
-  backports several important fixes from the 0.3.4.1-alpha.
-
-  The Tor 0.3.3 series includes controller support and other
-  improvements for v3 onion services, official support for embedding Tor
-  within other applications, and our first non-trivial module written in
-  the Rust programming language. (Rust is still not enabled by default
-  when building Tor.) And as usual, there are numerous other smaller
-  bugfixes, features, and improvements.
-
-  Below are the changes since 0.3.3.5-rc. For a list of all changes
-  since 0.3.2.10, see the ReleaseNotes file.
-
-  o Major bugfixes (directory authorities, security, backport from 0.3.4.1-alpha):
-    - When directory authorities read a zero-byte bandwidth file, they
-      would previously log a warning with the contents of an
-      uninitialised buffer. They now log a warning about the empty file
-      instead. Fixes bug 26007; bugfix on 0.2.2.1-alpha.
-
-  o Major bugfixes (security, directory authority, denial-of-service):
-    - Fix a bug that could have allowed an attacker to force a directory
-      authority to use up all its RAM by passing it a maliciously
-      crafted protocol versions string. Fixes bug 25517; bugfix on
-      0.2.9.4-alpha. This issue is also tracked as TROVE-2018-005.
-
-  o Major bugfixes (crash, backport from 0.3.4.1-alpha):
-    - Avoid a rare assertion failure in the circuit build timeout code
-      if we fail to allow any circuits to actually complete. Fixes bug
-      25733; bugfix on 0.2.2.2-alpha.
-
-  o Major bugfixes (directory authorities, backport from 0.3.4.1-alpha):
-    - Avoid a crash when testing router reachability on a router that
-      could have an ed25519 ID, but which does not. Fixes bug 25415;
-      bugfix on 0.3.3.2-alpha.
-
-  o Major bugfixes (onion service, backport from 0.3.4.1-alpha):
-    - Correctly detect when onion services get disabled after HUP. Fixes
-      bug 25761; bugfix on 0.3.2.1.
-
-  o Major bugfixes (relay, denial of service, backport from 0.3.4.1-alpha):
-    - Impose a limit on circuit cell queue size. The limit can be
-      controlled by a consensus parameter. Fixes bug 25226; bugfix
-      on 0.2.4.14-alpha.
-
-  o Minor features (compatibility, backport from 0.3.4.1-alpha):
-    - Avoid some compilation warnings with recent versions of LibreSSL.
-      Closes ticket 26006.
-
-  o Minor features (continuous integration, backport from 0.3.4.1-alpha):
-    - Our .travis.yml configuration now includes support for testing the
-      results of "make distcheck". (It's not uncommon for "make check"
-      to pass but "make distcheck" to fail.) Closes ticket 25814.
-    - Our Travis CI configuration now integrates with the Coveralls
-      coverage analysis tool. Closes ticket 25818.
-
-  o Minor features (geoip):
-    - Update geoip and geoip6 to the May 1 2018 Maxmind GeoLite2 Country
-      database. Closes ticket 26104.
-
-  o Minor bugfixes (client, backport from 0.3.4.1-alpha):
-    - Don't consider Tor running as a client if the ControlPort is open,
-      but no actual client ports are open. Fixes bug 26062; bugfix
-      on 0.2.9.4-alpha.
-
-  o Minor bugfixes (correctness, client, backport from 0.3.4.1-alpha):
-    - Upon receiving a malformed connected cell, stop processing the
-      cell immediately. Previously we would mark the connection for
-      close, but continue processing the cell as if the connection were
-      open. Fixes bug 26072; bugfix on 0.2.4.7-alpha.
-
-  o Minor bugfixes (documentation, backport from 0.3.4.1-alpha):
-    - Stop saying in the manual that clients cache ipv4 dns answers from
-      exit relays. We haven't used them since 0.2.6.3-alpha, and in
-      ticket 24050 we stopped even caching them as of 0.3.2.6-alpha, but
-      we forgot to say so in the man page. Fixes bug 26052; bugfix
-      on 0.3.2.6-alpha.
-
-  o Minor bugfixes (Linux seccomp2 sandbox, backport from 0.3.4.1-alpha):
-    - Allow the nanosleep() system call, which glibc uses to implement
-      sleep() and usleep(). Fixes bug 24969; bugfix on 0.2.5.1-alpha.
-
-  o Minor bugfixes (onion service, backport from 0.3.4.1-alpha):
-    - Fix a memory leak when a v3 onion service is configured and gets a
-      SIGHUP signal. Fixes bug 25901; bugfix on 0.3.2.1-alpha.
-    - When parsing the descriptor signature, look for the token plus an
-      extra white-space at the end. This is more correct but also will
-      allow us to support new fields that might start with "signature".
-      Fixes bug 26069; bugfix on 0.3.0.1-alpha.
-
-  o Minor bugfixes (relay, crash, backport from 0.3.4.1-alpha):
-    - Avoid a crash when running with DirPort set but ORPort tuned off.
-      Fixes a case of bug 23693; bugfix on 0.3.1.1-alpha.
-
-  o Documentation (backport from 0.3.4.1-alpha):
-    - Correct an IPv6 error in the documentation for ExitPolicy. Closes
-      ticket 25857. Patch from "CTassisF".

-Changes in version 0.3.3.6 - 2018-05-22
-  Tor 0.3.3.6 is the first stable release in the 0.3.3 series. It
-  backports several important fixes from the 0.3.4.1-alpha.
-
-  The Tor 0.3.3 series includes controller support and other

-  within other applications, and our first non-trivial module written in
-  the Rust programming language. (Rust is still not enabled by default

-
-  Below are the changes since 0.3.2.10. For a list of only the changes
-  since 0.3.3.5-rc, see the ChangeLog file.
-
-  o New system requirements:
-    - When built with Rust, Tor now depends on version 0.2.39 of the
-      libc crate. Closes tickets 25310 and 25664.
-
-  o Major features (embedding):
-    - There is now a documented stable API for programs that need to
-      embed Tor. See tor_api.h for full documentation and known bugs.
-      Closes ticket 23684.
-    - Tor now has support for restarting in the same process.
-      Controllers that run Tor using the "tor_api.h" interface can now
-      restart Tor after Tor has exited. This support is incomplete,
-      however: we fixed crash bugs that prevented it from working at
-      all, but many bugs probably remain, including a possibility of
-      security issues. Implements ticket 24581.
-
-  o Major features (IPv6, directory documents):
-    - Add consensus method 27, which adds IPv6 ORPorts to the microdesc
-      consensus. This information makes it easier for IPv6 clients to
-      bootstrap and choose reachable entry guards. Implements
-      ticket 23826.
-    - Add consensus method 28, which removes IPv6 ORPorts from
-      microdescriptors. Now that the consensus contains IPv6 ORPorts,
-      they are redundant in microdescs. This change will be used by Tor
-      clients on 0.2.8.x and later. (That is to say, with all Tor
-      clients that have IPv6 bootstrap and guard support.) Implements
-      ticket 23828.
-    - Expand the documentation for AuthDirHasIPv6Connectivity when it is
-      set by different numbers of authorities. Fixes 23870
-      on 0.2.4.1-alpha.
-
-  o Major features (onion service v3, control port):
-    - The control port now supports commands and events for v3 onion
-      services. It is now possible to create ephemeral v3 services using
-      ADD_ONION. Additionally, several events (HS_DESC, HS_DESC_CONTENT,
-      CIRC and CIRC_MINOR) and commands (GETINFO, HSPOST, ADD_ONION and
-      DEL_ONION) have been extended to support v3 onion services. Closes
-      ticket 20699; implements proposal 284.
-
-  o Major features (onion services):
-    - Provide torrc options to pin the second and third hops of onion
-      service circuits to a list of nodes. The option HSLayer2Guards
-      pins the second hop, and the option HSLayer3Guards pins the third
-      hop. These options are for use in conjunction with experiments
-      with "vanguards" for preventing guard enumeration attacks. Closes
-      ticket 13837.
-    - When v3 onion service clients send introduce cells, they now
-      include the IPv6 address of the rendezvous point, if it has one.
-      Current v3 onion services running 0.3.2 ignore IPv6 addresses, but
-      in future Tor versions, IPv6-only v3 single onion services will be
-      able to use IPv6 addresses to connect directly to the rendezvous
-      point. Closes ticket 23577. Patch by Neel Chauhan.
-
-  o Major features (relay):
-    - Implement an option, ReducedExitPolicy, to allow an Tor exit relay
-      operator to use a more reasonable ("reduced") exit policy, rather
-      than the default one. If you want to run an exit node without
-      thinking too hard about which ports to allow, this one is for you.
-      Closes ticket 13605. Patch from Neel Chauhan.
-
-  o Major features (rust, portability, experimental):
-    - Tor now ships with an optional implementation of one of its
-      smaller modules (protover.c) in the Rust programming language. To
-      try it out, install a Rust build environment, and configure Tor
-      with "--enable-rust --enable-cargo-online-mode". This should not
-      cause any user-visible changes, but should help us gain more
-      experience with Rust, and plan future Rust integration work.
-      Implementation by Chelsea Komlo. Closes ticket 22840.
-
-  o Major bugfixes (directory authorities, security, backport from 0.3.4.1-alpha):
-    - When directory authorities read a zero-byte bandwidth file, they
-      would previously log a warning with the contents of an
-      uninitialised buffer. They now log a warning about the empty file
-      instead. Fixes bug 26007; bugfix on 0.2.2.1-alpha.
-
-  o Major bugfixes (security, directory authority, denial-of-service):
-    - Fix a bug that could have allowed an attacker to force a directory
-      authority to use up all its RAM by passing it a maliciously
-      crafted protocol versions string. Fixes bug 25517; bugfix on
-      0.2.9.4-alpha. This issue is also tracked as TROVE-2018-005.
-
-  o Major bugfixes (crash, backport from 0.3.4.1-alpha):
-    - Avoid a rare assertion failure in the circuit build timeout code
-      if we fail to allow any circuits to actually complete. Fixes bug
-      25733; bugfix on 0.2.2.2-alpha.
-
-  o Major bugfixes (netflow padding):
-    - Stop adding unneeded channel padding right after we finish
-      flushing to a connection that has been trying to flush for many
-      seconds. Instead, treat all partial or complete flushes as
-      activity on the channel, which will defer the time until we need
-      to add padding. This fix should resolve confusing and scary log
-      messages like "Channel padding timeout scheduled 221453ms in the
-      past." Fixes bug 22212; bugfix on 0.3.1.1-alpha.
-
-  o Major bugfixes (networking):
-    - Tor will no longer reject IPv6 address strings from Tor Browser
-      when they are passed as hostnames in SOCKS5 requests. Fixes bug
-      25036, bugfix on Tor 0.3.1.2.
-
-  o Major bugfixes (onion service, backport from 0.3.4.1-alpha):
-    - Correctly detect when onion services get disabled after HUP. Fixes
-      bug 25761; bugfix on 0.3.2.1.
-
-  o Major bugfixes (performance, load balancing):
-    - Directory authorities no longer vote in favor of the Guard flag
-      for relays without directory support. Starting in Tor
-      0.3.0.1-alpha, clients have been avoiding using such relays in the
-      Guard position, leading to increasingly broken load balancing for
-      the 5%-or-so of Guards that don't advertise directory support.
-      Fixes bug 22310; bugfix on 0.3.0.6.
-
-  o Major bugfixes (relay):
-    - If we have failed to connect to a relay and received a connection
-      refused, timeout, or similar error (at the TCP level), do not try
-      that same address/port again for 60 seconds after the failure has
-      occurred. Fixes bug 24767; bugfix on 0.0.6.
-
-  o Major bugfixes (relay, denial of service, backport from 0.3.4.1-alpha):
-    - Impose a limit on circuit cell queue size. The limit can be
-      controlled by a consensus parameter. Fixes bug 25226; bugfix
-      on 0.2.4.14-alpha.
-
-  o Minor features (cleanup):
-    - Tor now deletes the CookieAuthFile and ExtORPortCookieAuthFile
-      when it stops. Closes ticket 23271.
-
-  o Minor features (compatibility, backport from 0.3.4.1-alpha):
-    - Avoid some compilation warnings with recent versions of LibreSSL.
-      Closes ticket 26006.
-
-  o Minor features (config options):
-    - Change the way the default value for MaxMemInQueues is calculated.
-      We now use 40% of the hardware RAM if the system has 8 GB RAM or
-      more. Otherwise we use the former value of 75%. Closes
-      ticket 24782.
-
-  o Minor features (continuous integration):
-    - Update the Travis CI configuration to use the stable Rust channel,
-      now that we have decided to require that. Closes ticket 25714.
-
-  o Minor features (continuous integration, backport from 0.3.4.1-alpha):
-    - Our .travis.yml configuration now includes support for testing the
-      results of "make distcheck". (It's not uncommon for "make check"
-      to pass but "make distcheck" to fail.) Closes ticket 25814.
-    - Our Travis CI configuration now integrates with the Coveralls
-      coverage analysis tool. Closes ticket 25818.
-
-  o Minor features (defensive programming):
-    - Most of the functions in Tor that free objects have been replaced
-      with macros that free the objects and set the corresponding
-      pointers to NULL. This change should help prevent a large class of
-      dangling pointer bugs. Closes ticket 24337.
-    - Where possible, the tor_free() macro now only evaluates its input
-      once. Part of ticket 24337.
-    - Check that microdesc ed25519 ids are non-zero in
-      node_get_ed25519_id() before returning them. Implements ticket
-      24001, patch by "aruna1234".
-
-  o Minor features (directory authority):
-    - When directory authorities are unable to add signatures to a
-      pending consensus, log the reason why. Closes ticket 24849.
-
-  o Minor features (embedding):
-    - Tor can now start with a preauthenticated control connection
-      created by the process that launched it. This feature is meant for
-      use by programs that want to launch and manage a Tor process
-      without allowing other programs to manage it as well. For more
-      information, see the __OwningControllerFD option documented in
-      control-spec.txt. Closes ticket 23900.
-    - On most errors that would cause Tor to exit, it now tries to
-      return from the tor_main() function, rather than calling the
-      system exit() function. Most users won't notice a difference here,
-      but it should be significant for programs that run Tor inside a
-      separate thread: they should now be able to survive Tor's exit
-      conditions rather than having Tor shut down the entire process.
-      Closes ticket 23848.
-    - Applications that want to embed Tor can now tell Tor not to
-      register any of its own POSIX signal handlers, using the
-      __DisableSignalHandlers option. Closes ticket 24588.
-
-  o Minor features (fallback directory list):
-    - Avoid selecting fallbacks that change their IP addresses too
-      often. Select more fallbacks by ignoring the Guard flag, and
-      allowing lower cutoffs for the Running and V2Dir flags. Also allow
-      a lower bandwidth, and a higher number of fallbacks per operator
-      (5% of the list). Implements ticket 24785.
-    - Update the fallback whitelist and blacklist based on opt-ins and
-      relay changes. Closes tickets 22321, 24678, 22527, 24135,
-      and 24695.
-
-  o Minor features (fallback directory mirror configuration):
-    - Add a nickname to each fallback in a C comment. This makes it
-      easier for operators to find their relays, and allows stem to use
-      nicknames to identify fallbacks. Implements ticket 24600.
-    - Add a type and version header to the fallback directory mirror
-      file. Also add a delimiter to the end of each fallback entry. This
-      helps external parsers like stem and Relay Search. Implements
-      ticket 24725.
-    - Add an extrainfo cache flag for each fallback in a C comment. This
-      allows stem to use fallbacks to fetch extra-info documents, rather
-      than using authorities. Implements ticket 22759.
-    - Add the generateFallbackDirLine.py script for automatically
-      generating fallback directory mirror lines from relay fingerprints.
-      No more typos! Add the lookupFallbackDirContact.py script for
-      automatically looking up operator contact info from relay
-      fingerprints. Implements ticket 24706, patch by teor and atagar.
-    - Reject any fallback directory mirror that serves an expired
-      consensus. Implements ticket 20942, patch by "minik".
-    - Remove commas and equals signs from external string inputs to the
-      fallback list. This avoids format confusion attacks. Implements
-      ticket 24726.
-    - Remove the "weight=10" line from fallback directory mirror
-      entries. Ticket 24681 will maintain the current fallback weights
-      by changing Tor's default fallback weight to 10. Implements
-      ticket 24679.
-    - Stop logging excessive information about fallback netblocks.
-      Implements ticket 24791.
-
-  o Minor features (forward-compatibility):
-    - If a relay supports some link authentication protocol that we do
-      not recognize, then include that relay's ed25519 key when telling
-      other relays to extend to it. Previously, we treated future
-      versions as if they were too old to support ed25519 link
-      authentication. Closes ticket 20895.
-
-  o Minor features (geoip):
-    - Update geoip and geoip6 to the May 1 2018 Maxmind GeoLite2 Country
-      database. Closes ticket 26104.
-
-  o Minor features (heartbeat):
-    - Add onion service information to our heartbeat logs, displaying
-      stats about the activity of configured onion services. Closes
-      ticket 24896.
-
-  o Minor features (instrumentation, development):
-    - Add the MainloopStats option to allow developers to get
-      instrumentation information from the main event loop via the
-      heartbeat messages. We hope to use this to improve Tor's behavior
-      when it's trying to sleep. Closes ticket 24605.
-
-  o Minor features (IPv6):
-    - Make IPv6-only clients wait for microdescs for relays, even if we
-      were previously using descriptors (or were using them as a bridge)
-      and have a cached descriptor for them. Implements ticket 23827.
-    - When a consensus has IPv6 ORPorts, make IPv6-only clients use
-      them, rather than waiting to download microdescriptors. Implements
-      ticket 23827.
-
-  o Minor features (log messages):
-    - Improve log message in the out-of-memory handler to include
-      information about memory usage from the different compression
-      backends. Closes ticket 25372.
-    - Improve a warning message that happens when we fail to re-parse an
-      old router because of an expired certificate. Closes ticket 20020.
-    - Make the log more quantitative when we hit MaxMemInQueues
-      threshold exposing some values. Closes ticket 24501.
-
-  o Minor features (logging):
-    - Clarify the log messages produced when getrandom() or a related
-      entropy-generation mechanism gives an error. Closes ticket 25120.
-    - Added support for the Android logging subsystem. Closes
-      ticket 24362.
-
-  o Minor features (performance):
-    - Support predictive circuit building for onion service circuits
-      with multiple layers of guards. Closes ticket 23101.
-    - Use stdatomic.h where available, rather than mutexes, to implement
-      atomic_counter_t. Closes ticket 23953.
-
-  o Minor features (performance, 32-bit):
-    - Improve performance on 32-bit systems by avoiding 64-bit division
-      when calculating the timestamp in milliseconds for channel padding
-      computations. Implements ticket 24613.
-    - Improve performance on 32-bit systems by avoiding 64-bit division
-      when timestamping cells and buffer chunks for OOM calculations.
-      Implements ticket 24374.
-
-  o Minor features (performance, OSX, iOS):
-    - Use the mach_approximate_time() function (when available) to
-      implement coarse monotonic time. Having a coarse time function
-      should avoid a large number of system calls, and improve
-      performance slightly, especially under load. Closes ticket 24427.
-
-  o Minor features (performance, windows):
-    - Improve performance on Windows Vista and Windows 7 by adjusting
-      TCP send window size according to the recommendation from
-      SIO_IDEAL_SEND_BACKLOG_QUERY. Closes ticket 22798. Patch
-      from Vort.
-
-  o Minor features (sandbox):
-    - Explicitly permit the poll() system call when the Linux
-      seccomp2-based sandbox is enabled: apparently, some versions of
-      libc use poll() when calling getpwnam(). Closes ticket 25313.
-
-  o Minor features (storage, configuration):
-    - Users can store cached directory documents somewhere other than
-      the DataDirectory by using the CacheDirectory option. Similarly,
-      the storage location for relay's keys can be overridden with the
-      KeyDirectory option. Closes ticket 22703.
-
-  o Minor features (testing):
-    - Add a "make test-rust" target to run the rust tests only. Closes
-      ticket 25071.
-
-  o Minor features (testing, debugging, embedding):
-    - For development purposes, Tor now has a mode in which it runs for
-      a few seconds, then stops, and starts again without exiting the
-      process. This mode is meant to help us debug various issues with
-      ticket 23847. To use this feature, compile with
-      --enable-restart-debugging, and set the TOR_DEBUG_RESTART
-      environment variable. This is expected to crash a lot, and is
-      really meant for developers only. It will likely be removed in a
-      future release. Implements ticket 24583.
-
-  o Minor bugfixes (build, rust):
-    - Fix output of autoconf checks to display success messages for Rust
-      dependencies and a suitable rustc compiler version. Fixes bug
-      24612; bugfix on 0.3.1.3-alpha.
-    - Don't pass the --quiet option to cargo: it seems to suppress some
-      errors, which is not what we want to do when building. Fixes bug
-      24518; bugfix on 0.3.1.7.
-    - Build correctly when building from outside Tor's source tree with
-      the TOR_RUST_DEPENDENCIES option set. Fixes bug 22768; bugfix
-      on 0.3.1.7.
-
-  o Minor bugfixes (C correctness):
-    - Fix a very unlikely (impossible, we believe) null pointer
-      dereference. Fixes bug 25629; bugfix on 0.2.9.15. Found by
-      Coverity; this is CID 1430932.
-
-  o Minor bugfixes (channel, client):
-    - Better identify client connection when reporting to the geoip
-      client cache. Fixes bug 24904; bugfix on 0.3.1.7.
-
-  o Minor bugfixes (circuit, cannibalization):
-    - Don't cannibalize preemptively-built circuits if we no longer
-      recognize their first hop. This situation can happen if our Guard
-      relay went off the consensus after the circuit was created. Fixes
-      bug 24469; bugfix on 0.0.6.
-
-  o Minor bugfixes (client, backport from 0.3.4.1-alpha):
-    - Don't consider Tor running as a client if the ControlPort is open,
-      but no actual client ports are open. Fixes bug 26062; bugfix
-      on 0.2.9.4-alpha.
-
-  o Minor bugfixes (compilation):
-    - Fix a C99 compliance issue in our configuration script that caused
-      compilation issues when compiling Tor with certain versions of
-      xtools. Fixes bug 25474; bugfix on 0.3.2.5-alpha.
-
-  o Minor bugfixes (controller):
-    - Restore the correct operation of the RESOLVE command, which had
-      been broken since we added the ability to enable/disable DNS on
-      specific listener ports. Fixes bug 25617; bugfix on 0.2.9.3-alpha.
-    - Avoid a (nonfatal) assertion failure when extending a one-hop
-      circuit from the controller to become a multihop circuit. Fixes
-      bug 24903; bugfix on 0.2.5.2-alpha.
-
-  o Minor bugfixes (correctness):
-    - Remove a nonworking, unnecessary check to see whether a circuit
-      hop's identity digest was set when the circuit failed. Fixes bug
-      24927; bugfix on 0.2.4.4-alpha.
-
-  o Minor bugfixes (correctness, client, backport from 0.3.4.1-alpha):
-    - Upon receiving a malformed connected cell, stop processing the
-      cell immediately. Previously we would mark the connection for
-      close, but continue processing the cell as if the connection were
-      open. Fixes bug 26072; bugfix on 0.2.4.7-alpha.
-
-  o Minor bugfixes (directory authorities, IPv6):
-    - When creating a routerstatus (vote) from a routerinfo (descriptor),
-      set the IPv6 address to the unspecified IPv6 address, and
-      explicitly initialize the port to zero. Fixes bug 24488; bugfix
-      on 0.2.4.1-alpha.
-
-  o Minor bugfixes (documentation):
-    - Document that the PerConnBW{Rate,Burst} options will fall back to
-      their corresponding consensus parameters only if those parameters
-      are set. Previously we had claimed that these values would always
-      be set in the consensus. Fixes bug 25296; bugfix on 0.2.2.7-alpha.
-
-  o Minor bugfixes (documentation, backport from 0.3.4.1-alpha):
-    - Stop saying in the manual that clients cache ipv4 dns answers from
-      exit relays. We haven't used them since 0.2.6.3-alpha, and in
-      ticket 24050 we stopped even caching them as of 0.3.2.6-alpha, but
-      we forgot to say so in the man page. Fixes bug 26052; bugfix
-      on 0.3.2.6-alpha.
-
-  o Minor bugfixes (exit relay DNS retries):
-    - Re-attempt timed-out DNS queries 3 times before failure, since our
-      timeout is 5 seconds for them, but clients wait 10-15. Also allow
-      slightly more timeouts per resolver when an exit has multiple
-      resolvers configured. Fixes bug 21394; bugfix on 0.3.1.9.
-
-  o Minor bugfixes (fallback directory mirrors):
-    - Make updateFallbackDirs.py search harder for python. (Some OSs
-      don't put it in /usr/bin.) Fixes bug 24708; bugfix
-      on 0.2.8.1-alpha.
-
-  o Minor bugfixes (hibernation, bandwidth accounting, shutdown):
-    - When hibernating, close connections normally and allow them to
-      flush. Fixes bug 23571; bugfix on 0.2.4.7-alpha. Also fixes
-      bug 7267.
-    - Do not attempt to launch self-reachability tests when entering
-      hibernation. Fixes a case of bug 12062; bugfix on 0.0.9pre5.
-    - Resolve several bugs related to descriptor fetching on bridge
-      clients with bandwidth accounting enabled. (This combination is
-      not recommended!) Fixes a case of bug 12062; bugfix
-      on 0.2.0.3-alpha.
-    - When hibernating, do not attempt to launch DNS checks. Fixes a
-      case of bug 12062; bugfix on 0.1.2.2-alpha.
-    - When hibernating, do not try to upload or download descriptors.
-      Fixes a case of bug 12062; bugfix on 0.0.9pre5.
-
-  o Minor bugfixes (IPv6, bridges):
-    - Tor now always sets IPv6 preferences for bridges. Fixes bug 24573;
-      bugfix on 0.2.8.2-alpha.
-    - Tor now sets IPv6 address in the routerstatus as well as in the
-      router descriptors when updating addresses for a bridge. Closes
-      ticket 24572; bugfix on 0.2.4.5-alpha. Patch by "ffmancera".
-
-  o Minor bugfixes (Linux seccomp2 sandbox):
-    - When running with the sandbox enabled, reload configuration files
-      correctly even when %include was used. Previously we would crash.
-      Fixes bug 22605; bugfix on 0.3.1. Patch from Daniel Pinto.
-
-  o Minor bugfixes (Linux seccomp2 sandbox, backport from 0.3.4.1-alpha):
-    - Allow the nanosleep() system call, which glibc uses to implement
-      sleep() and usleep(). Fixes bug 24969; bugfix on 0.2.5.1-alpha.
-
-  o Minor bugfixes (logging):
-    - Fix a (mostly harmless) race condition when invoking
-      LOG_PROTOCOL_WARN message from a subthread while the torrc options
-      are changing. Fixes bug 23954; bugfix on 0.1.1.9-alpha.
-
-  o Minor bugfixes (man page, SocksPort):
-    - Remove dead code from the old "SocksSocket" option, and rename
-      SocksSocketsGroupWritable to UnixSocksGroupWritable. The old
-      option still works, but is deprecated. Fixes bug 24343; bugfix
-      on 0.2.6.3.
-
-  o Minor bugfixes (memory leaks):
-    - Avoid possible at-exit memory leaks related to use of Libevent's
-      event_base_once() function. (This function tends to leak memory if
-      the event_base is closed before the event fires.) Fixes bug 24584;
-      bugfix on 0.2.8.1-alpha.
-    - Fix a harmless memory leak in tor-resolve. Fixes bug 24582; bugfix
-      on 0.2.1.1-alpha.
-
-  o Minor bugfixes (network IPv6 test):
-    - Tor's test scripts now check if "ping -6 ::1" works when the user
-      runs "make test-network-all". Fixes bug 24677; bugfix on
-      0.2.9.3-alpha. Patch by "ffmancera".
-
-  o Minor bugfixes (networking):
-    - string_is_valid_hostname() will not consider IP strings to be
-      valid hostnames. Fixes bug 25055; bugfix on Tor 0.2.5.5.
-
-  o Minor bugfixes (onion service v3):
-    - Avoid an assertion failure when the next onion service descriptor
-      rotation type is out of sync with the consensus's valid-after
-      time. Instead, log a warning message with extra information, so we
-      can better hunt down the cause of this assertion. Fixes bug 25306;
-      bugfix on 0.3.2.1-alpha.
-
-  o Minor bugfixes (onion service, backport from 0.3.4.1-alpha):
-    - Fix a memory leak when a v3 onion service is configured and gets a
-      SIGHUP signal. Fixes bug 25901; bugfix on 0.3.2.1-alpha.
-    - When parsing the descriptor signature, look for the token plus an
-      extra white-space at the end. This is more correct but also will
-      allow us to support new fields that might start with "signature".
-      Fixes bug 26069; bugfix on 0.3.0.1-alpha.
-
-  o Minor bugfixes (onion services):
-    - If we are configured to offer a single onion service, don't log
-      long-term established one hop rendezvous points in the heartbeat.
-      Fixes bug 25116; bugfix on 0.2.9.6-rc.
-
-  o Minor bugfixes (performance):
-    - Reduce the number of circuits that will be opened at once during
-      the circuit build timeout phase. This is done by increasing the
-      idle timeout to 3 minutes, and lowering the maximum number of
-      concurrent learning circuits to 10. Fixes bug 24769; bugfix
-      on 0.3.1.1-alpha.
-    - Avoid calling protocol_list_supports_protocol() from inside tight
-      loops when running with cached routerinfo_t objects. Instead,
-      summarize the relevant protocols as flags in the routerinfo_t, as
-      we do for routerstatus_t objects. This change simplifies our code
-      a little, and saves a large amount of short-term memory allocation
-      operations. Fixes bug 25008; bugfix on 0.2.9.4-alpha.
-
-  o Minor bugfixes (performance, timeouts):
-    - Consider circuits for timeout as soon as they complete a hop. This
-      is more accurate than applying the timeout in
-      circuit_expire_building() because that function is only called
-      once per second, which is now too slow for typical timeouts on the
-      current network. Fixes bug 23114; bugfix on 0.2.2.2-alpha.
-    - Use onion service circuits (and other circuits longer than 3 hops)
-      to calculate a circuit build timeout. Previously, Tor only
-      calculated its build timeout based on circuits that planned to be
-      exactly 3 hops long. With this change, we include measurements
-      from all circuits at the point where they complete their third
-      hop. Fixes bug 23100; bugfix on 0.2.2.2-alpha.
-
-  o Minor bugfixes (relay, crash, backport from 0.3.4.1-alpha):
-    - Avoid a crash when running with DirPort set but ORPort tuned off.
-      Fixes a case of bug 23693; bugfix on 0.3.1.1-alpha.
-
-  o Minor bugfixes (Rust FFI):
-    - Fix a minor memory leak which would happen whenever the C code
-      would call the Rust implementation of
-      protover_get_supported_protocols(). This was due to the C version
-      returning a static string, whereas the Rust version newly allocated
-      a CString to pass accross the FFI boundary. Consequently, the C
-      code was not expecting to need to free() what it was given. Fixes
-      bug 25127; bugfix on 0.3.2.1-alpha.
-
-  o Minor bugfixes (spelling):
-    - Use the "misspell" tool to detect and fix typos throughout the
-      source code. Fixes bug 23650; bugfix on various versions of Tor.
-      Patch from Deepesh Pathak.
-
-  o Minor bugfixes (testing):
-    - Avoid intermittent test failures due to a test that had relied on
-      onion service introduction point creation finishing within 5
-      seconds of real clock time. Fixes bug 25450; bugfix
-      on 0.3.1.3-alpha.
-    - Give out Exit flags in bootstrapping networks. Fixes bug 24137;
-      bugfix on 0.2.3.1-alpha.
-
-  o Minor bugfixes (unit test, monotonic time):
-    - Increase a constant (1msec to 10msec) in the monotonic time test
-      that makes sure the nsec/usec/msec times read are synchronized.
-      This change was needed to accommodate slow systems like armel or
-      when the clock_gettime() is not a VDSO on the running kernel.
-      Fixes bug 25113; bugfix on 0.2.9.1.
-
-  o Code simplification and refactoring:
-    - Move the list of default directory authorities to its own file.
-      Closes ticket 24854. Patch by "beastr0".
-    - Remove the old (deterministic) directory retry logic entirely:
-      We've used exponential backoff exclusively for some time. Closes
-      ticket 23814.
-    - Remove the unused nodelist_recompute_all_hsdir_indices(). Closes
-      ticket 25108.
-    - Remove a series of counters used to track circuit extend attempts
-      and connection status but that in reality we aren't using for
-      anything other than stats logged by a SIGUSR1 signal. Closes
-      ticket 25163.
-    - Remove /usr/athena from search path in configure.ac. Closes
-      ticket 24363.
-    - Remove duplicate code in node_has_curve25519_onion_key() and
-      node_get_curve25519_onion_key(), and add a check for a zero
-      microdesc curve25519 onion key. Closes ticket 23966, patch by
-      "aruna1234" and teor.
-    - Rewrite channel_rsa_id_group_set_badness to reduce temporary
-      memory allocations with large numbers of OR connections (e.g.
-      relays). Closes ticket 24119.
-    - Separate the function that deletes ephemeral files when Tor
-      stops gracefully.
-    - Small changes to Tor's buf_t API to make it suitable for use as a
-      general-purpose safe string constructor. Closes ticket 22342.
-    - Switch -Wnormalized=id to -Wnormalized=nfkc in configure.ac to
-      avoid source code identifier confusion. Closes ticket 24467.
-    - The tor_git_revision[] constant no longer needs to be redeclared
-      by everything that links against the rest of Tor. Done as part of
-      ticket 23845, to simplify our external API.
-    - We make extend_info_from_node() use node_get_curve25519_onion_key()
-      introduced in ticket 23577 to access the curve25519 public keys
-      rather than accessing it directly. Closes ticket 23760. Patch by
-      Neel Chauhan.
-    - Add a function to log channels' scheduler state changes to aid
-      debugging efforts. Closes ticket 24531.
-
-  o Documentation:
-    - Improved the documentation of AccountingStart parameter. Closes
-      ticket 23635.
-    - Update the documentation for "Log" to include the current list of
-      logging domains. Closes ticket 25378.
-    - Add documentation on how to build tor with Rust dependencies
-      without having to be online. Closes ticket 22907; bugfix
-      on 0.3.0.3-alpha.
-    - Clarify the behavior of RelayBandwidth{Rate,Burst} with client
-      traffic. Closes ticket 24318.
-    - Document that OutboundBindAddress doesn't apply to DNS requests.
-      Closes ticket 22145. Patch from Aruna Maurya.
-
-  o Code simplification and refactoring (channels):
-    - Remove the incoming and outgoing channel queues. These were never
-      used, but still took up a step in our fast path.
-    - The majority of the channel unit tests have been rewritten and the
-      code coverage has now been raised to 83.6% for channel.c. Closes
-      ticket 23709.
-    - Remove other dead code from the channel subsystem: All together,
-      this cleanup has removed more than 1500 lines of code overall and
-      adding very little except for unit test.
-
-  o Code simplification and refactoring (circuit rendezvous):
-    - Split the client-side rendezvous circuit lookup into two
-      functions: one that returns only established circuits and another
-      that returns all kinds of circuits. Closes ticket 23459.
-
-  o Code simplification and refactoring (controller):
-    - Make most of the variables in networkstatus_getinfo_by_purpose()
-      const. Implements ticket 24489.
-
-  o Documentation (backport from 0.3.4.1-alpha):
-    - Correct an IPv6 error in the documentation for ExitPolicy. Closes
-      ticket 25857. Patch from "CTassisF".
-
-  o Documentation (man page):
-    - The HiddenServiceVersion torrc option accepts only one number:
-      either version 2 or 3. Closes ticket 25026; bugfix
-      on 0.3.2.2-alpha.
-
-  o Documentation (manpage, denial of service):
-    - Provide more detail about the denial-of-service options, by
-      listing each mitigation and explaining how they relate. Closes
-      ticket 25248.
-
-
