+Changes in version 0.4.0.6 - 2019-12-??
+  This is the second stable release in the 0.4.0.x series. This release
+  backports several bugfixes to improve stability and correctness.  Anyone
+  experiencing build problems or crashes with 0.4.0.5, including all relays
+  relying on AccountingMax, should upgrade.
+
+  Note that, per our support policy, support for the 0.4.0.x series will end
+  on 2 Feb 2020.  Anyone still running 0.4.0.x should plan to upgrade to the
+  latest stable release, or downgrade to 0.3.5.x, which will get long-term
+  support until 1 Feb 2022.
+
+  o Directory authority changes (backport from 0.4.1.5):
+    - The directory authority "dizum" has a new IP address. Closes
+      ticket 31406.
+
+  o Major bugfixes (bridges, backport from 0.4.1.2-alpha):
+    - Consider our directory information to have changed when our list
+      of bridges changes. Previously, Tor would not re-compute the
+      status of its directory information when bridges changed, and
+      therefore would not realize that it was no longer able to build
+      circuits. Fixes part of bug 29875.
+    - Do not count previously configured working bridges towards our
+      total of working bridges. Previously, when Tor's list of bridges
+      changed, it would think that the old bridges were still usable,
+      and delay fetching router descriptors for the new ones. Fixes part
+      of bug 29875; bugfix on 0.3.0.1-alpha.
+
+  o Major bugfixes (circuit build, guard, backport from 0.4.1.4-rc):
+    - When considering upgrading circuits from "waiting for guard" to
+      "open", always ignore circuits that are marked for close. Otherwise,
+      we can end up in the situation where a subsystem is notified that
+      a closing circuit has just opened, leading to undesirable
+      behavior. Fixes bug 30871; bugfix on 0.3.0.1-alpha.
+
+  o Major bugfixes (Onion service reachability, backport from 0.4.1.3-alpha):
+    - Properly clean up the introduction point map when circuits change
+      purpose from onion service circuits to pathbias, measurement, or
+      other circuit types. This should fix some service-side instances
+      of introduction point failure. Fixes bug 29034; bugfix
+      on 0.3.2.1-alpha.
+
+  o Major bugfixes (onion service v3, backport from 0.4.1.1-alpha):
+    - Fix an unreachable bug in which an introduction point could try to
+      send an INTRODUCE_ACK with a status code that Trunnel would refuse
+      to encode, leading the relay to assert(). We've consolidated the
+      ABI values into Trunnel now. Fixes bug 30454; bugfix
+      on 0.3.0.1-alpha.
+    - Clients can now handle unknown status codes from INTRODUCE_ACK
+      cells. (The NACK behavior will stay the same.) This will allow us
+      to extend status codes in the future without breaking the normal
+      client behavior. Fixes another part of bug 30454; bugfix
+      on 0.3.0.1-alpha.
+
+  o Major bugfixes (relay, backport from 0.4.2.3-alpha):
+    - Relays now respect their AccountingMax bandwidth again. When
+      relays entered "soft" hibernation (which typically starts when
+      we've hit 90% of our AccountingMax), we had stopped checking
+      whether we should enter hard hibernation. Soft hibernation refuses
+      new connections and new circuits, but the existing circuits can
+      continue, meaning that relays could have exceeded their configured
+      AccountingMax. Fixes bug 32108; bugfix on 0.4.0.1-alpha.
+
+  o Major bugfixes (torrc parsing, backport from 0.4.2.2-alpha):
+    - Stop ignoring torrc options after an %include directive, when the
+      included directory ends with a file that does not contain any
+      config options (but does contain comments or whitespace). Fixes
+      bug 31408; bugfix on 0.3.1.1-alpha.
+
+  o Major bugfixes (v3 onion services, backport from 0.4.2.3-alpha):
+    - Onion services now always use the exact number of intro points
+      configured with the HiddenServiceNumIntroductionPoints option (or
+      fewer if nodes are excluded). Before, a service could sometimes
+      pick more intro points than configured. Fixes bug 31548; bugfix
+      on 0.3.2.1-alpha.
+
+  o Minor features (compile-time modules, backport from version 0.4.1.1-alpha):
+    - Add a "--list-modules" command to print a list of which compile-
+      time modules are enabled. Closes ticket 30452.
+
+  o Minor features (continuous integration, backport from 0.4.1.1-alpha):
+    - Remove sudo configuration lines from .travis.yml as they are no
+      longer needed with current Travis build environment. Resolves
+      issue 30213.
+
+  o Minor features (continuous integration, backport from 0.4.1.4-rc):
+    - Our Travis configuration now uses Chutney to run some network
+      integration tests automatically. Closes ticket 29280.
+
+  o Minor features (continuous integration, backport from 0.4.2.2-alpha):
+    - When building on Appveyor and Travis, pass the "-k" flag to make,
+      so that we are informed of all compilation failures, not just the
+      first one or two. Closes ticket 31372.
+
+  o Minor features (fallback directory list, backport from 0.4.1.4-rc):
+    - Replace the 157 fallbacks originally introduced in Tor 0.3.5.6-rc
+      in December 2018 (of which ~122 were still functional), with a
+      list of 148 fallbacks (70 new, 78 existing, 79 removed) generated
+      in June 2019. Closes ticket 28795.
+
+  o Minor features (geoip, backport from 0.4.2.4-rc):
+    - Update geoip and geoip6 to the November 6 2019 Maxmind GeoLite2
+      Country database. Closes ticket 32440.
+
+  o Minor features (stem tests, backport from 0.4.2.1-alpha):
+    - Change "make test-stem" so it only runs the stem tests that use
+      tor. This change makes test-stem faster and more reliable. Closes
+      ticket 31554.
+
+  o Minor bugfixes (Appveyor CI, backport from 0.4.2.2-alpha):
+    - Avoid spurious errors when Appveyor CI fails before the install step.
+      Fixes bug 31884; bugfix on 0.3.4.2-alpha.
+
+  o Minor bugfixes (build system, backport form 0.4.2.1-alpha):
+    - Do not include the deprecated <sys/sysctl.h> on Linux or Windows
+      systems. Fixes bug 31673; bugfix on 0.2.5.4-alpha.
+
+  o Minor bugfixes (circuit isolation, backport from 0.4.1.3-alpha):
+    - Fix a logic error that prevented the SessionGroup sub-option from
+      being accepted. Fixes bug 22619; bugfix on 0.2.7.2-alpha.
+
+  o Minor bugfixes (circuit padding, backport from 0.4.1.4-rc):
+    - On relays, properly check that a padding machine is absent before
+      logging a warning about it being absent. Fixes bug 30649; bugfix
+      on 0.4.0.1-alpha.
+
+  o Minor bugfixes (client, onion service v3, backport from 0.4.2.4-rc):
+    - Fix a BUG() assertion that occurs within a very small race window
+      between when a client intro circuit opens and when its descriptor
+      gets cleaned up from the cache. The circuit is now closed early,
+      which will trigger a re-fetch of the descriptor and continue the
+      connection. Fixes bug 28970; bugfix on 0.3.2.1-alpha.
+
+  o Minor bugfixes (clock skew detection, backport from 0.4.1.5):
+    - Don't believe clock skew results from NETINFO cells that appear to
+      arrive before we sent the VERSIONS cells they are responding to.
+      Previously, we would accept them up to 3 minutes "in the past".
+      Fixes bug 31343; bugfix on 0.2.4.4-alpha.
+
+  o Minor bugfixes (compilation warning, backport from 0.4.1.5):
+    - Fix a compilation warning on Windows about casting a function
+      pointer for GetTickCount64(). Fixes bug 31374; bugfix
+      on 0.2.9.1-alpha.
+
+  o Minor bugfixes (compilation, backport from 0.4.1.5):
+    - Avoid using labs() on time_t, which can cause compilation warnings
+      on 64-bit Windows builds. Fixes bug 31343; bugfix on 0.2.4.4-alpha.
+
+  o Minor bugfixes (compilation, backport from 0.4.2.1-alpha):
+    - Suppress spurious float-conversion warnings from GCC when calling
+      floating-point classifier functions on FreeBSD. Fixes part of bug
+      31687; bugfix on 0.3.1.5-alpha.
+
+  o Minor bugfixes (compilation, unusual configurations, backport from 0.4.1.1-alpha):
+    - Avoid failures when building with the ALL_BUGS_ARE_FATAL option
+      due to missing declarations of abort(), and prevent other such
+      failures in the future. Fixes bug 30189; bugfix on 0.3.4.1-alpha.
+
+  o Minor bugfixes (configuration, proxies, backport from 0.4.1.2-alpha):
+    - Fix a bug that prevented us from supporting SOCKS5 proxies that
+      want authentication along with configured (but unused!)
+      ClientTransportPlugins. Fixes bug 29670; bugfix on 0.2.6.1-alpha.
+
+  o Minor bugfixes (connections, backport from 0.4.2.3-rc):
+    - Avoid trying to read data from closed connections, which can cause
+      needless loops in Libevent and infinite loops in Shadow. Fixes bug
+      30344; bugfix on 0.1.1.1-alpha.
+
+  o Minor bugfixes (continuous integration, backport from 0.4.1.3-alpha):
+    - Allow the test-stem job to fail in Travis, because it sometimes
+      hangs. Fixes bug 30744; bugfix on 0.3.5.4-alpha.
+    - Skip test_rebind on macOS in Travis, because it is unreliable on
+      macOS on Travis. Fixes bug 30713; bugfix on 0.3.5.1-alpha.
+    - Skip test_rebind when the TOR_SKIP_TEST_REBIND environment
+      variable is set. Fixes bug 30713; bugfix on 0.3.5.1-alpha.
+
+  o Minor bugfixes (crash on exit, backport from 0.4.1.4-rc):
+    - Avoid a set of possible code paths that could try to use freed
+      memory in routerlist_free() while Tor was exiting. Fixes bug
+      31003; bugfix on 0.1.2.2-alpha.
+
+  o Minor bugfixes (directory authorities, backport from 0.4.1.3-alpha):
+    - Stop crashing after parsing an unknown descriptor purpose
+      annotation. We think this bug can only be triggered by modifying a
+      local file. Fixes bug 30781; bugfix on 0.2.0.8-alpha.
+
+  o Minor bugfixes (directory authority, backport from 0.4.1.2-alpha):
+    - Move the "bandwidth-file-headers" line in directory authority
+      votes so that it conforms to dir-spec.txt. Fixes bug 30316; bugfix
+      on 0.3.5.1-alpha.
+
+  o Minor bugfixes (error handling, backport from 0.4.2.1-alpha):
+    - On abort, try harder to flush the output buffers of log messages.
+      On some platforms (macOS), log messages could be discarded when
+      the process terminates. Fixes bug 31571; bugfix on 0.3.5.1-alpha.
+    - Report the tor version whenever an assertion fails. Previously, we
+      only reported the Tor version on some crashes, and some non-fatal
+      assertions. Fixes bug 31571; bugfix on 0.3.5.1-alpha.
+
+  o Minor bugfixes (FreeBSD, PF-based proxy, IPv6, backport from 0.4.2.1-alpha):
+    - When extracting an IPv6 address from a PF-based proxy, verify that
+      we are actually configured to receive an IPv6 address, and log an
+      internal error if not. Fixes part of bug 31687; bugfix
+      on 0.2.3.4-alpha.
+
+  o Minor bugfixes (guards, backport from 0.4.2.1-alpha):
+    - When tor is missing descriptors for some primary entry guards,
+      make the log message less alarming. It's normal for descriptors to
+      expire, as long as tor fetches new ones soon after. Fixes bug
+      31657; bugfix on 0.3.3.1-alpha.
+
+  o Minor bugfixes (logging, backport from 0.4.1.1-alpha):
+    - Do not log a warning when running with an OpenSSL version other
+      than the one Tor was compiled with, if the two versions should be
+      compatible. Previously, we would warn whenever the version was
+      different. Fixes bug 30190; bugfix on 0.2.4.2-alpha.
+
+  o Minor bugfixes (logging, backport from 0.4.2.1-alpha):
+    - Change log level of message "Hash of session info was not as
+      expected" to LOG_PROTOCOL_WARN. Fixes bug 12399; bugfix
+      on 0.1.1.10-alpha.
+
+  o Minor bugfixes (logging, backport from 0.4.2.2-alpha):
+    - Rate-limit our the logging message about the obsolete .exit
+      notation. Previously, there was no limit on this warning, which
+      could potentially be triggered many times by a hostile website.
+      Fixes bug 31466; bugfix on 0.2.2.1-alpha.
+
+  o Minor bugfixes (logging, protocol violations, backport from 0.4.2.2-alpha):
+    - Do not log a nonfatal assertion failure when receiving a VERSIONS
+      cell on a connection using the obsolete v1 link protocol. Log a
+      protocol_warn instead. Fixes bug 31107; bugfix on 0.2.4.4-alpha.
+
+  o Minor bugfixes (mainloop, periodic events, in-process API, backport from 0.4.2.3-alpha):
+    - Reset the periodic events' "enabled" flag when Tor is shut down
+      cleanly. Previously, this flag was left on, which caused periodic
+      events not to be re-enabled when Tor was relaunched in-process
+      with tor_api.h after a shutdown. Fixes bug 32058; bugfix
+      on 0.3.3.1-alpha.
+
+  o Minor bugfixes (memory leak, backport from 0.4.1.1-alpha):
+    - Avoid a minor memory leak that could occur on relays when failing
+      to create a "keys" directory. Fixes bug 30148; bugfix
+      on 0.3.3.1-alpha.
+
+  o Minor bugfixes (memory leak, backport from 0.4.1.4-rc):
+    - Fix a trivial memory leak when parsing an invalid value
+      from a download schedule in the configuration. Fixes bug
+      30894; bugfix on 0.3.4.1-alpha.
+
+  o Minor bugfixes (NetBSD, backport from 0.4.1.2-alpha):
+    - Fix usage of minherit() on NetBSD and other platforms that define
+      MAP_INHERIT_{ZERO,NONE} instead of INHERIT_{ZERO,NONE}. Fixes bug
+      30614; bugfix on 0.4.0.2-alpha. Patch from Taylor Campbell.
+
+  o Minor bugfixes (onion services, backport from 0.4.1.1-alpha):
+    - Avoid a GCC 9.1.1 warning (and possible crash depending on libc
+      implemenation) when failing to load an onion service client
+      authorization file. Fixes bug 30475; bugfix on 0.3.5.1-alpha.
+
+  o Minor bugfixes (out-of-memory handler, backport from 0.4.1.2-alpha):
+    - When purging the DNS cache because of an out-of-memory condition,
+      try purging just the older entries at first. Previously, we would
+      always purge the whole thing. Fixes bug 29617; bugfix
+      on 0.3.5.1-alpha.
+
+  o Minor bugfixes (portability, backport from 0.4.1.2-alpha):
+    - Avoid crashing in our tor_vasprintf() implementation on systems
+      that define neither vasprintf() nor _vscprintf(). (This bug has
+      been here long enough that we question whether people are running
+      Tor on such systems, but we're applying the fix out of caution.)
+      Fixes bug 30561; bugfix on 0.2.8.2-alpha. Found and fixed by
+      Tobias Stoeckmann.
+
+  o Minor bugfixes (process management, backport from 0.4.2.3-alpha):
+    - Remove overly strict assertions that triggered when a pluggable
+      transport failed to launch. Fixes bug 31091; bugfix
+      on 0.4.0.1-alpha.
+    - Remove an assertion in the Unix process backend. This assertion
+      would trigger when we failed to find the executable for a child
+      process. Fixes bug 31810; bugfix on 0.4.0.1-alpha.
+
+  o Minor bugfixes (relay, backport from 0.4.2.2-alpha):
+    - Avoid crashing when starting with a corrupt keys directory where
+      the old ntor key and the new ntor key are identical. Fixes bug
+      30916; bugfix on 0.2.4.8-alpha.
+
+  o Minor bugfixes (rust, backport from 0.4.2.1-alpha):
+    - Correctly exclude a redundant rust build job in Travis. Fixes bug
+      31463; bugfix on 0.3.5.4-alpha.
+
+  o Minor bugfixes (testing, backport from 0.4.2.3-alpha):
+    - When testing port rebinding, don't busy-wait for tor to log.
+      Instead, actually sleep for a short time before polling again.
+      Also improve the formatting of control commands and log messages.
+      Fixes bug 31837; bugfix on 0.3.5.1-alpha.
+
+  o Minor bugfixes (tls, logging, backport from 0.4.2.3-alpha):
+    - Log bugs about the TLS read buffer's length only once, rather than
+      filling the logs with similar warnings. Fixes bug 31939; bugfix
+      on 0.3.0.4-rc.
+
+  o Minor bugfixes (v2 single onion services, backport from 0.4.2.1-alpha):
+    - Always retry v2 single onion service intro and rend circuits with
+      a 3-hop path. Previously, v2 single onion services used a 3-hop
+      path when rendezvous circuits were retried after a remote or
+      delayed failure, but a 1-hop path for immediate retries. Fixes bug
+      23818; bugfix on 0.2.9.3-alpha.
+    - Make v3 single onion services fall back to a 3-hop intro, when all
+      intro points are unreachable via a 1-hop path. Previously, v3
+      single onion services failed when all intro nodes were unreachable
+      via a 1-hop path. Fixes bug 23507; bugfix on 0.3.2.1-alpha.
+
+  o Documentation (backport from 0.4.2.1-alpha):
+    - Use RFC 2397 data URL scheme to embed an image into tor-exit-
+      notice.html so that operators no longer have to host it
+      themselves. Closes ticket 31089.
+
+  o Testing (backport from 0.4.1.2-alpha):
+    - Specify torrc paths (with empty files) when launching tor in

+
+  o Testing (continuous integration, backport from 0.4.1.1-alpha):

+      ticket 30694.
+
+  o Testing (continuous integration, backport from 0.4.2.3-alpha):
+    - Disable all but one Travis CI macOS build, to mitigate slow
+      scheduling of Travis macOS jobs. Closes ticket 32177.
+    - Run the chutney IPv6 networks as part of Travis CI. Closes
+      ticket 30860.

+      Appveyor builds. Closes ticket 32086.
+
+  o Testing (continuous integration, backport from 0.4.2.4-rc):
+    - Use Ubuntu Bionic images for our Travis CI builds, so we can get a
+      recent version of coccinelle. But leave chutney on Ubuntu Trusty,
+      until we can fix some Bionic permissions issues (see ticket
+      32240). Related to ticket 31919.
+    - Install the mingw OpenSSL package in Appveyor. This makes sure
+      that the OpenSSL headers and libraries match in Tor's Appveyor
+      builds. (This bug was triggered by an Appveyor image update.)
+      Fixes bug 32449; bugfix on 0.3.5.6-rc.
+    - In Travis, use Xcode 11.2 on macOS 10.14. Closes ticket 32241.
+
+  o Testing (continuous integration, backport from 0.4.2.5):
+    - Require C99 standards-conforming code in Travis CI, but allow GNU gcc
+      extensions. Also activates clang's -Wtypedef-redefinition warnings.
+      Build some jobs with -std=gnu99, and some jobs without.
+      Closes ticket 32500.
