changes/bug40190

-  o Minor bugfixes (SOCKS5):
-    - Handle partial socks5 messages correctly.  Previously, our code would

changes/bug40210

-  o Minor features (crypto):
-    - Fix undefined behavior on our Keccak library. The bug only appears on
-      platforms with 32-byte CPU cache lines (e.g. armv5tel) and would result
-      in wrong digests. Fixes bug 40210; bugfix on 0.2.8.1-alpha. Thanks to
-      Bernhard Übelacker, Arnd Bergmann and weasel for diagnosing this.

changes/ticket33624

-  o Minor bugfixes (configure, static build):
-    - Change our search library configure macro linker flag order so it works

changes/ticket40106

-  o Minor bugfixes (config, bridge):
-    - Don't initiate a connection to a bridge without a corresponding
-      transport. Fixes bug 40106; bugfix on 0.4.5.1-alpha.
-    - This also reverts an earlier fix we did for this that would validate
-      configuration to avoid such situation but turns out it wouldn't work for
-      a DisableNetwork thus the new approach.

changes/ticket40111

-  o Minor bugfixes (configure, build):
-    - Fix the --enable-static-tor switch to properly set the -static compile
-      option onto the tor binary only. Fixes bug 40111; bugfix on
-      0.2.3.1-alpha.
-    - Path to static libevent has been fixed as well which affects the
-      --enable-static-libevent to behave correctly now. The .a file is in
-      .libs/ of libevent repository, not at the root.

changes/ticket40188

-  o Minor features (documentation):
-    - Mention the !badexit directive that can appear in an authority's
-      approved-routers file, and update the description of the !invalid
-      directive. Closes ticket 40188.

changes/ticket40201

-  o Minor bugfixes (logging, relay):
-    - Logs the address discovered by the directory authorities if none were
-      configured or detected before. Fixes bug 40201; bugfix on 0.4.5.1-alpha.

changes/ticket40205

-  o Minor bugfixes (relay, logging, reachability):
-    - When launching bandwidth testing circuit, don't log notice that we are
-      doing a reachability test. Furthermore, avoid to trigger a
-      "CHECKING_REACHABILITY" control event. Fixes bug 40205; bugfix on
-      0.4.5.1-alpha.

changes/ticket40226

-  o Minor bugfixes (relay, statistics):
-    - The connection statistics were wrongly exported in the extrainfo document
-      due to a problem in the file loading function which would wrongly truncate
-      the file reporting the wrong information. It is now fixed. Fixes bug
-      40226; bugfix on 0.4.5.1-alpha.

changes/ticket40231

-  o Minor bugfixes (relay):
-    - If we were unable to build our descriptor, don't mark that we've
-      advertised our descriptor. Also remove an harmless BUG(). Fixes bug 40231;
-      bugfix on 0.4.5.1-alpha.

changes/ticket40237

-  o Major bugfixes (onion service v3):
-    - Stop requiring a live consensus for v3 clients and services to work. The
-      use of a reasonably live consensus will allow v3 to work properly in most
-      cases if the network failed to generate a consensus for more than 2 hours
-      in a row. Fixes bug 40237; bugfix on 0.3.5.1-alpha.

changes/ticket40243

-  o Major bugfixes (authority, IPv6):
-    - Do not consider multiple relays in the same IPv6 network to be sybils.
-      Sybils are selected based on the /128 now, not the /64. Fixes bug 40243;
-      bugfix on 0.4.5.1-alpha.

changes/ticket40245

-  o Minor features (logging):
-    - Give more visibility to directory authority operators during the
-      consensus voting process and while processing relay descriptors.
-      Closes ticket 40245.
