 Changes in version 0.4.2.1-alpha - 2019-09-??
+  This is the first alpha release in the 0.4.2.x series. BLURB
+  BLURB BLURB.
+
+  o New system requirements (build system):
+    - Do not include the deprecated <sys/sysctl.h> on Linux or Windows
+      system. Closes 31673;
 
   o Major features (developer tools):
-    - Our best-practices tracker now integrates with our include-checker tool
-      to keep track of the layering violations that we have not yet fixed.
-      We hope to reduce this number over time to improve Tor's modularity.
-      Closes ticket 31176.

+      fixed. We hope to reduce this number over time to improve Tor's
+      modularity. Closes ticket 31176.
 
   o Major features (onion service v3, denial of service):
-    - Add onion service introduction denial of service defenses. They consist of
-      rate limiting client introduction at the intro point using parameters that
-      can be sent by the service within the ESTABLISH_INTRO cell. If the cell
-      extension for this is not used, the intro point will honor the consensus
-      parameters. Closes ticket 30924.

+      ticket 30924.
 
   o Major bugfixes (circuit build, guard):
-    - When considering upgrading circuits from "waiting for guard" to "open",
-      always ignore the ones that are mark for close. Else, we can end up in
-      the situation where a subsystem is notified of that circuit opening but
-      still marked for close leading to undesirable behavior. Fixes bug 30871;
-      bugfix on 0.3.0.1-alpha.

   o Major bugfixes (crash, android):
-    - Tolerate systems (including some Android installations) where madvise
-      and MADV_DONTDUMP are available at build-time, but not at run time.
-      Previously, these systems would notice a failed syscall and abort.

-      HSDir. Closes ticket 24964;
+    - Do not allow single hop client to fetch or post an HS descriptor
+      from an HSDir. Closes ticket 24964;
 
   o Minor feature (onion service):
-    - Disallow single hop clients to introduce directly at the introduction
-      point. We've removed Tor2web a while back and rendezvous are blocked at
-      the relays. This is to remove load off the network from spammy clients.
-      Close ticket 24963.

   o Minor feature (token bucket):
-    - Implement a generic token bucket that uses a single counter. This will be
-      useful for the anti-DoS onion service work. Closes ticket 30687.

   o Minor features (best practices tracker):
-    - Add a TOR_PRACTRACKER_OPTIONS variable for passing arguments
-      to practracker from the environment. We may want this for
-      continuous integration. Closes ticket 31309.
-    - Give a warning rather than an error when a practracker exception is
-      violated by a small amount; add a --list-overbroad option to
-      practracker that lists exceptions that are stricter than they need to
-      be, and provide an environment variable for disabling

   o Minor features (build system):
-    - Add --disable-manpage and --disable-html-manual options to configure
-      script. This will enable shortening build times by not building
-      documentation. Resolves issue 19381.

+      configure script. This will enable shortening build times by not
+      building documentation. Resolves issue 19381.
 
   o Minor features (compilation):
-    - Log a more useful error message when we are compiling and one of the
-      compile-time hardening options we have selected can be linked but
-      not executed. Closes ticket 27530.
+    - Log a more useful error message when we are compiling and one of
+      the compile-time hardening options we have selected can be linked
+      but not executed. Closes ticket 27530.
 
   o Minor features (configuration):
     - The configuration code has been extended to allow splitting
       configuration data across multiple objects. Previously, all
       configuration data needed to be kept in a single object, which
-      tended to become bloated.  Closes ticket 31240.
+      tended to become bloated. Closes ticket 31240.
 
   o Minor features (continuous integration):
-    - When running CI builds on Travis, put some random data in ~/.torrc,
-      to make sure no tests are dependent on default Tor configuration.
-      Resolves issue 30102.

+      ~/.torrc, to make sure no tests are dependent on default Tor
+      configuration. Resolves issue 30102.
 
   o Minor features (debugging):
     - Log a nonfatal assertion failure if we encounter a configuration
-      line whose command is "CLEAR" but which has a nonempty value.
-      This should be impossible, according to the rules of our
-      configuration line parsing. Closes ticket 31529.

-      C files. Closes ticket 31175.
+    - Our best-practices tracker now looks at headers as well as C
+      files. Closes ticket 31175.
 
   o Minor features (git hooks):
-    - Our pre-commit git hook now checks for a special file
-      before running practracker, so that practracker only runs on branches
-      that are based on master. Since the pre-push hook calls the pre-commit
-      hook, practracker will also only run before pushes of branches based
-      on master.

+      commit hook, practracker will also only run before pushes of
+      branches based on master. Closes ticket 30979.
 
   o Minor features (git scripts):
-    - Add a "--" command-line argument, to
-      separate git-push-all.sh script arguments from arguments that are passed
-      through to git push. Closes ticket 31314.
-    - Add a -r <remote-name> argument to git-push-all.sh, so the script can
-      push test branches to a personal remote. Closes ticket 31314.
+    - Add a "--" command-line argument, to separate git-push-all.sh

+    - Add a -r <remote-name> argument to git-push-all.sh, so the script
+      can push test branches to a personal remote. Closes ticket 31314.
     - Add a -t <test-branch-prefix> argument to git-merge-forward.sh and
-      git-push-all.sh, which makes these scripts create, merge forward, and
-      push test branches. Closes ticket 31314.
-    - Add a -u argument to git-merge-forward.sh, so that the script can re-use
-      existing test branches after a merge failure and fix.
+      git-push-all.sh, which makes these scripts create, merge forward,

+      re-use existing test branches after a merge failure and fix.
       Closes ticket 31314.
-    - Add a TOR_GIT_PUSH env var, which sets the default git push command and
-      arguments for git-push-all.sh. Closes ticket 31314.
-    - Add a TOR_PUSH_DELAY variable to git-push-all.sh, which makes the script
-      push master and maint branches with a delay between each branch. These
-      delays trigger the CI jobs in a set order, which should show the most
-      likely failures first. Also make pushes atomic by default, and make
-      the script pass any command-line arguments to git push.
-      Closes ticket 29879.
-    - Call the shellcheck script from the pre-commit hook.
-      Closes ticket 30967.

+      ticket 30967.
     - Skip pushing test branches that are the same as a remote
-      maint/release/master branch in git-push-all.sh by default. Add a -s
-      argument, so git-push-all.sh can push all test branches.
-      Closes ticket 31314.

   o Minor features (IPv6, logging):
     - Log IPv6 addresses as well as IPv4 addresses, when describing
       routerinfos, routerstatuses, and nodes. Closes ticket 21003.
 
   o Minor features (recommended packages):
-    - No longer include recommended packages in votes as detailed in proposal
-      301. The RecommendedPackages torrc option is deprecated and will no
-      longer have any effect. "package" lines will still be considered when
-      computing consensuses for consensus methods that include them. Fixes
-      ticket 29738.

   o Minor features (stem tests):
-    - 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.

+      ticket 31554.
 
   o Minor features (testing):
-    - Add a script to invoke "tor --dump-config" and "tor --verify-config"
-      with various configuration options, and see whether tor's resulting
-      configuration or error messages are what we expect. Use it for
-      integration testing of our +Option and /Option flags.

     - Improve test coverage for our existing configuration parsing and
       management API. Closes ticket 30893.
 
   o Minor features (tests):
-    - Add integration tests to make sure that practracker gives the outputs
-      we expect. Closes ticket 31477.

   o Minor bugfixes (best practices tracker):
-    - Fix a few issues in the best-practices script, including tests, tab
-      tolerance, error reporting, and directory-exclusion logic. Fixes bug

   o Minor bugfixes (chutney, makefiles, documentation):
-    - "make test-network-all" shows the warnings from each test-network.sh
-      run on the console, so developers see new warnings early. Improve the
-      documentation for this feature, and rename a Makefile variable so the
-      code is self-documenting. Fixes bug 30455; bugfix on 0.3.0.4-rc.

   o Minor bugfixes (compilation):
-    - Add more stub functions to fix compilation on Android with LTO, when
-      --disable-module-dirauth is used. Previously, these compilation
-      settings would make the compiler look for functions that didn't exist.
-      Fixes bug 31552; bugfix on 0.4.1.1-alpha.

   o Minor bugfixes (configuration):
     - Invalid floating-point values in the configuration file are now
       detected treated as errors in the configuration. Previously, they
-      were ignored and treated as zero. Fixes bug 31475; bugfix on
-      0.0.1.

+      on 0.0.1.
 
   o Minor bugfixes (coverity compliance):
-    - Add an assertion when parsing a BEGIN cell so that coverity can be sure
-      that we are not about to dereference a NULL address.
-      Fixes bug 31026; bugfix on 0.2.4.7-alpha.  This is CID
-      1447296.

   o Minor bugfixes (coverity):
-    - In our siphash implementation, when building for coverity, use memcpy
-      in place of a switch statement, so that coverity can tell we are not
-      accessing out-of-bounds memory. Fixes bug 31025; bugfix on
-      0.2.8.1-alpha.  This is tracked as CID 1447293 and 1447295.

   o Minor bugfixes (coverity, tests):
-    - Fix several coverity warnings from our unit tests. Fixes bug 31030;
-      bugfix on 0.2.4.1-alpha, 0.3.2.1-alpha, and 0.4.0.1-alpha.

   o Minor bugfixes (developer tooling):
-    - Only log git script changes in post-merge script when merge was to the
-      master branch. Fixes bug 31040; bugfix on 0.4.1.1-alpha.

+      bug 30780; bugfix on 0.2.0.8-alpha.
 
   o Minor bugfixes (error handling):
-    - On abort, try harder to flush the output buffers of log messages. On
-      some platforms (macOS), log messages can 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.

     - When tor aborts due to an error, close log file descriptors before
       aborting. Closing the logs makes some OSes flush log file buffers,
-      rather than deleting buffered log lines. Fixes bug 31594;

   o Minor bugfixes (git scripts):
     - Stop hard-coding the bash path in the git scripts. Some OSes don't
       have bash in /usr/bin, others have an ancient bash at this path.
       Fixes bug 30840; bugfix on 0.4.0.1-alpha.

   o Minor bugfixes (guards):
-    - 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;

   o Minor bugfixes (ipv6):
-    - We check for private IPv6 address alongside their IPv4 equivalents when
-      authorities check descriptors. Previously, we only checked for private
-      IPv4 addresses. Fixes bug 31088; bugfix on 0.2.3.21-rc. Patch by Neel
-      Chauhan.
-    - When parsing microdescriptors, we should check the IPv6 exit policy
-      alongside IPv4. Previously, we checked both exit policies for only
-      router info structures, while microdescriptors were IPv4-only. Fixes

   o Minor bugfixes (networking, IP addresses):
-    - When parsing addreses via Tor's internal DNS lookup API, reject IPv4
-      addresses in square brackets, and accept IPv6 addresses in square
-      brackets. This change completes the work started in 23082, making
-      address parsing consistent between tor's internal DNS lookup and address
-      parsing APIs. Fixes bug 30721; bugfix on 0.2.1.5-alpha.

   o Minor bugfixes (onion service v3):
     - When purging the client descriptor cache, always also close any

-      a more general tool.  Now typed structure members are accessible
-      via an abstract type. Implements ticket 30914.

     - Move our backend logic for working with configuration and state
       files into a lower-level library, since in no longer depends on
       any tor-specific functionality. Closes ticket 31626.
-    - Numerous simplifications in configuration-handling logic:
