changes/happy-families-client

+  o Major features (client):
+    - Clients now respect "happy families" per proposal 321.
+      This feature will eventually allow a much more compact representation
+      for relay families, for a significant savings in directory download size.

changes/ticket28970

-  o Minor bugfixes (clietn, hidden service v3):
-    - Fix a BUG() assertion that occurs within a very small race window between
-      a client intro circuit opens and its descriptor that gets cleaned up from
-      the cache. The circuit is now closed which will trigger a re-fetch of the
-      descriptor and continue the HS connection. Fixes bug 28970; bugfix on
-      0.3.2.1-alpha.

changes/ticket29603

-  o Minor features (git scripts):
-    - Add git-setup-dirs.sh, which sets up an upstream git repository and
-      worktrees for tor maintainers. Closes ticket 29603.

changes/ticket31241

-  o Minor features (configuration validation):
-    - Configuration validation can now be done by per-module callbacks,
-      rather than a global validation function.  This will let us reduce the
-      size of config.c and some of its more cumbersome functions.  Closes
-      ticket 31241.

changes/ticket31336

-  o Minor bugfixes (developer tools):
-    - Allow paths starting with ./ in scripts/add_c_file.py. Fixes bug 
-      31336; bugfix on 0.4.1.2-alpha.

changes/ticket31373

-  o Minor feature (configure, build system):
-    - Output enabled/disabled features at the end of the configure process in a
-      pleasing way. Closes ticket 31373.

changes/ticket31524

+  o Major bugfix (control-events, bw-cache):
+    - Fixes spikes occurring in bandwidth cache on control connection.
+      Fixes bug 31524; bugfix on 0.4.8.12-dev.

changes/ticket31684

-  o Minor features (controller):
-    - Implement a new GETINFO command to fetch microdescriptor consensus.
-      Closes ticket 31684.
-  o Code simplification and refactoring (controller):
-    - Create a helper function that can fetch network status or microdesc
-      consensuses. Closes ticket 31684.

changes/ticket31705

-  o Minor features (developer tools):
-    - Add some scripts in "scripts/coccinelle" to invoke the Coccinelle
-      semantic patching tool with the correct flags.  These flags are fairly
-      easy to forget, and these scripts should help us use Coccinelle more
-      effectively in the future. Closes ticket 31705.
-
-  o Code simplification and refactoring:
-    - Fix some parts of our code that were difficult for Coccinelle to parse.
-      Related to ticket 31705.

changes/ticket31919

-  o Minor features (developer tools):
-    - Add a check_cocci_parse.sh script that checks that new code
-      is parseable by Coccinelle. Add an exceptions file for unparseable
-      files. Closes ticket 31919.
-    - Call the check_cocci_parse.sh script from a 'check-cocci' Makefile
-      target. Closes ticket 31919.
-  o Minor features (git scripts):
-    - Call the check_cocci_parse.sh script from the git commit and push hooks.
-      Closes ticket 31919.
-    - Skip unmodified source files when doing some existing git hook checks.
-      Related to ticket 31919.
-  o Minor features (continuous integration):
-    - Call the check_cocci_parse.sh script from Travis CI. Closes ticket 31919.

changes/ticket31919_bionic

-  o Minor features (continuous integration):
-    - 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.

changes/ticket31958

-  o Minor bugfixes (directory):
-    - When checking if a directory connection is anonymous, test if the circuit
-      was marked for close before looking at its channel. This avoids a BUG()
-      stacktrace in case it was previously closed. Fixes bug 31958; bugfix on
-      0.4.2.1-alpha.

changes/ticket31999

-  o Code simplification and refactoring:
-    - Our default log (which ordinarily sends NOTICE-level message to
-      standard output) is now handled in a more logical manner. Previously,
-      we replaced the configured log options if they were empty.
-      Now, we interpret an empty set of log options as meaning "use the
-      default log". Closes ticket 31999.

changes/ticket32003

-  o Code simplification and refactoring:
-    - When parsing the command line, handle options that determine our "quiet
-      level" and our mode of operation (e.g., --dump-config and so on)
-      all in one table. Closes ticket 32003.

changes/ticket32094

-  o Minor bugfixes (hidden service v3):
-    - Do not rely on a "circuit established" flag for intro circuit but instead
-      always query the HS circuit map. This is to avoid sync issue with that
-      flag and the map. Fixes bug 32094; bugfix on 0.3.2.1-alpha.

changes/ticket32099

-  o Removed features:
-    - Our Doxygen configuration no longer generates LaTeX output.  The
-      reference manual produced by doing this was over 4000 pages long,
-      and generally unusable.  Closes ticket 32099.

changes/ticket32110

-  o Minor features (Doxygen):
-
-    - Update Doxygen configuration file to a more recent template (from
-      1.8.15).  Closes ticket 32110.

changes/ticket32113

-  o Minor features (doxygen):
-    - "make doxygen" now works with out-of-tree builds. Closes ticket
-      32113.

changes/ticket32123

-  o Major features (build system):
-    - Create an optional relay module, which can be disabled using the
-      --disable-module-relay configure option. When it is set, also disable
-      the dirauth module. Add a minimal implemention, which disables the
-      relay and dircache modes in tor. Closes ticket 32123.

changes/ticket32176

-  o Documentation (manpage):
-    - In the tor(1) manpage, reword and improve formatting of the
-      FILES, SEE ALSO, and BUGS sections.  Closes ticket 32176.  Based
-      on work by Swati Thacker as part of Google Season of Docs.
