+Changes in version 0.3.3.5-rc - 2018-04-15
+  Tor 0.3.3.5-rc fixes various bugs in earlier versions of Tor,
+  including some that could affect reliability or correctness.
+
+  This is the first release candidate in the 0.3.3 series. If we find no
+  new bugs or regression here, then the first stable 0.3.3 release will
+  be nearly identical to this one.
+
+  o Major bugfixes (security, protover, voting):
+    - Revise Rust implementation of protover to use a more memory-
+      efficient voting algorithm and corresponding data structures, thus
+      avoiding a potential memory-based DoS attack where specially
+      crafted protocol strings would expand to fill available memory.
+      Fixes bug 24031; bugfix on 0.3.3.1-alpha.
+
+  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 Minor feature (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 (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 (geoip):
+    - Update geoip and geoip6 to the April 3 2018 Maxmind GeoLite2
+      Country database. Closes ticket 25718.
+
+  o Minor bugfixes (client):
+    - When using a listed relay as a bridge, and also using
+      microdescriptors, and considering that relay as a non-bridge in a
+      circuit, treat its microdescriptor as a valid source of
+      information about that relay. This change should prevent a non-
+      fatal assertion error. Fixes bug 25691; bugfix on 0.3.3.4-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.
+
+  o Minor bugfixes (distribution, compilation, rust):
+    - Build correctly when the rust dependencies submodule is loaded,
+      but the TOR_RUST_DEPENDENCIES environment variable is not set.
+      Fixes bug 25679; bugfix on 0.3.3.1-alpha.
+    - Actually include all of our Rust source in our source
+      distributions. (Previously, a few of the files were accidentally
+      omitted.) Fixes bug 25732; bugfix on 0.3.3.2-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.
+    - Revert a misformatting issue in the ExitPolicy documentation.
+      Fixes bug 25582; bugfix on 0.3.3.1-alpha.
+
+  o Minor bugfixes (exit node 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 (onion services):
+    - Re-instate counting the client HSDir fetch circuits against the
+      MaxClientCircuitsPending rate limit. Fixes bug 24989; bugfix
+      on 0.3.3.1-alpha.
+    - Remove underscores from the _HSLayer{2,3}Nodes options. This
+      expert-user configuration can now be enabled as HSLayer{2,3}Nodes.
+      Fixes bug 25581; bugfix on 0.3.3.1-alpha
+
+  o Code simplification and refactoring:
+    - Move the list of default directory authorities to its own file.
+      Closes ticket 24854. Patch by "beastr0".
+
+  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.
