+Changes in version 0.3.4.9 - 2018-11-02
+  Tor 0.3.4.9 is the second stable release in its series; it backports
+  numerous fixes, including a fix for a bandwidth management bug that
+  was causing memory exhaustion on relays. Anyone running an earlier
+  version of Tor 0.3.4.9 should upgrade.
+
+  o Major bugfixes (compilation, backport from 0.3.5.3-alpha):
+    - Fix compilation on ARM (and other less-used CPUs) when compiling
+      with OpenSSL before 1.1. Fixes bug 27781; bugfix on 0.3.4.1-alpha.
+
+  o Major bugfixes (mainloop, bootstrap, backport from 0.3.5.3-alpha):
+    - Make sure Tor bootstraps and works properly if only the
+      ControlPort is set. Prior to this fix, Tor would only bootstrap
+      when a client port was set (Socks, Trans, NATD, DNS or HTTPTunnel
+      port). Fixes bug 27849; bugfix on 0.3.4.1-alpha.
+
+  o Major bugfixes (relay, backport from 0.3.5.3-alpha):
+    - When our write bandwidth limit is exhausted, stop writing on the
+      connection. Previously, we had a typo in the code that would make
+      us stop reading instead, leading to relay connections being stuck
+      indefinitely and consuming kernel RAM. Fixes bug 28089; bugfix
+      on 0.3.4.1-alpha.
+
+  o Major bugfixes (restart-in-process, backport from 0.3.5.1-alpha):
+    - Fix a use-after-free error that could be caused by passing Tor an
+      impossible set of options that would fail during options_act().
+      Fixes bug 27708; bugfix on 0.3.3.1-alpha.
+
+  o Minor features (continuous integration, backport from 0.3.5.1-alpha):
+    - Don't do a distcheck with --disable-module-dirauth in Travis.
+      Implements ticket 27252.
+    - Only run one online rust build in Travis, to reduce network
+      errors. Skip offline rust builds on Travis for Linux gcc, because
+      they're redundant. Implements ticket 27252.
+    - Skip gcc on OSX in Travis CI, because it's rarely used. Skip a
+      duplicate hardening-off build in Travis on Tor 0.2.9. Skip gcc on
+      Linux with default settings, because all the non-default builds
+      use gcc on Linux. Implements ticket 27252.
+
+  o Minor features (continuous integration, backport from 0.3.5.3-alpha):
+    - Use the Travis Homebrew addon to install packages on macOS during
+      Travis CI. The package list is the same, but the Homebrew addon
+      does not do a `brew update` by default. Implements ticket 27738.
+
+  o Minor features (geoip):
+    - Update geoip and geoip6 to the October 9 2018 Maxmind GeoLite2
+      Country database. Closes ticket 27991.
+
+  o Minor bugfixes (32-bit OSX and iOS, timing, backport from 0.3.5.2-alpha):
+    - Fix an integer overflow bug in our optimized 32-bit millisecond-
+      difference algorithm for 32-bit Apple platforms. Previously, it
+      would overflow when calculating the difference between two times
+      more than 47 days apart. Fixes part of bug 27139; bugfix
+      on 0.3.4.1-alpha.
+    - Improve the precision of our 32-bit millisecond difference
+      algorithm for 32-bit Apple platforms. Fixes part of bug 27139;
+      bugfix on 0.3.4.1-alpha.
+    - Relax the tolerance on the mainloop/update_time_jumps test when
+      running on 32-bit Apple platforms. Fixes part of bug 27139; bugfix
+      on 0.3.4.1-alpha.
+
+  o Minor bugfixes (C correctness, to appear in 0.3.5.4-alpha):
+    - Avoid undefined behavior in an end-of-string check when parsing
+      the BEGIN line in a directory object. Fixes bug 28202; bugfix
+      on 0.2.0.3-alpha.
+
+  o Minor bugfixes (CI, appveyor, to appear in 0.3.5.4-alpha):
+    - Only install the necessary mingw packages during our appveyor
+      builds. This change makes the build a little faster, and prevents
+      a conflict with a preinstalled mingw openssl that appveyor now
+      ships. Fixes bugs 27943 and 27765; bugfix on 0.3.4.2-alpha.
+
+  o Minor bugfixes (code safety, backport from 0.3.5.3-alpha):
+    - Rewrite our assertion macros so that they no longer suppress the
+      compiler's -Wparentheses warnings. Fixes bug 27709; bugfix
+
+  o Minor bugfixes (continuous integration, backport from 0.3.5.1-alpha):
+    - Stop reinstalling identical packages in our Windows CI. Fixes bug
+      27464; bugfix on 0.3.4.1-alpha.
+
+  o Minor bugfixes (directory authority, to appear in 0.3.5.4-alpha):
+    - Log additional info when we get a relay that shares an ed25519 ID
+      with a different relay, instead making a BUG() warning. Fixes bug
+      27800; bugfix on 0.3.2.1-alpha.
+
+  o Minor bugfixes (directory connection shutdown, backport from 0.3.5.1-alpha):
+    - Avoid a double-close when shutting down a stalled directory
+      connection. Fixes bug 26896; bugfix on 0.3.4.1-alpha.
+
+  o Minor bugfixes (HTTP tunnel, backport from 0.3.5.1-alpha):
+    - Fix a bug warning when closing an HTTP tunnel connection due to an
+      HTTP request we couldn't handle. Fixes bug 26470; bugfix
+      on 0.3.2.1-alpha.
+
+  o Minor bugfixes (netflow padding, backport from 0.3.5.1-alpha):
+    - Ensure circuitmux queues are empty before scheduling or sending
+      padding. Fixes bug 25505; bugfix on 0.3.1.1-alpha.
+
+  o Minor bugfixes (onion service v3, backport from 0.3.5.1-alpha):
+    - When the onion service directory can't be created or has the wrong
+      permissions, do not log a stack trace. Fixes bug 27335; bugfix
+      on 0.3.2.1-alpha.
+
+  o Minor bugfixes (onion service v3, backport from 0.3.5.2-alpha):
+    - Close all SOCKS request (for the same .onion) if the newly fetched
+      descriptor is unusable. Before that, we would close only the first
+      one leaving the other hanging and let to time out by themselves.
+      Fixes bug 27410; bugfix on 0.3.2.1-alpha.
+
+  o Minor bugfixes (onion service v3, backport from 0.3.5.3-alpha):
+    - When selecting a v3 rendezvous point, don't only look at the
+      protover, but also check whether the curve25519 onion key is
+      present. This way we avoid picking a relay that supports the v3
+      rendezvous but for which we don't have the microdescriptor. Fixes
+      bug 27797; bugfix on 0.3.2.1-alpha.
+
+  o Minor bugfixes (protover, backport from 0.3.5.3-alpha):
+    - Reject protocol names containing bytes other than alphanumeric
+      characters and hyphens ([A-Za-z0-9-]). Fixes bug 27316; bugfix
+      on 0.2.9.4-alpha.
+
+  o Minor bugfixes (rust, backport from 0.3.5.1-alpha):
+    - Compute protover votes correctly in the rust version of the
+      protover code. Previously, the protover rewrite in 24031 allowed
+      repeated votes from the same voter for the same protocol version
+      to be counted multiple times in protover_compute_vote(). Fixes bug
+      27649; bugfix on 0.3.3.5-rc.
+    - Reject protover names that contain invalid characters. Fixes bug
+      27687; bugfix on 0.3.3.1-alpha.
+
+  o Minor bugfixes (rust, backport from 0.3.5.2-alpha):
+    - protover_all_supported() would attempt to allocate up to 16GB on
+      some inputs, leading to a potential memory DoS. Fixes bug 27206;
+      bugfix on 0.3.3.5-rc.
+
+  o Minor bugfixes (rust, directory authority, to appear in 0.3.5.4-alpha):
+    - Fix an API mismatch in the rust implementation of
+      protover_compute_vote(). This bug could have caused crashes on any
+      directory authorities running Tor with Rust (which we do not yet
+      recommend). Fixes bug 27741; bugfix on 0.3.3.6.
+
+  o Minor bugfixes (rust, to appear in 0.3.5.4-alpha):
+    - Fix a potential null dereference in protover_all_supported(). Add
+      a test for it. Fixes bug 27804; bugfix on 0.3.3.1-alpha.
+    - Return a string that can be safely freed by C code, not one
+      created by the rust allocator, in protover_all_supported(). Fixes
+      bug 27740; bugfix on 0.3.3.1-alpha.
+
+  o Minor bugfixes (testing, backport from 0.3.5.1-alpha):
+    - If a unit test running in a subprocess exits abnormally or with a
+      nonzero status code, treat the test as having failed, even if the
+      test reported success. Without this fix, memory leaks don't cause
+      the tests to fail, even with LeakSanitizer. Fixes bug 27658;
+      bugfix on 0.2.2.4-alpha.
+
+  o Minor bugfixes (testing, backport from 0.3.5.3-alpha):
+    - Make the hs_service tests use the same time source when creating
+      the introduction point and when testing it. Now tests work better
+      on very slow systems like ARM or Travis. Fixes bug 27810; bugfix
+      on 0.3.2.1-alpha.
+
+  o Minor bugfixes (testing, to appear in 0.3.5.4-alpha):
+    - Treat backtrace test failures as expected on BSD-derived systems
+      (NetBSD, OpenBSD, and macOS/Darwin) until we solve bug 17808.
+      (FreeBSD failures have been treated as expected since 18204 in
+      0.2.8.) Fixes bug 27948; bugfix on 0.2.5.2-alpha.

 Changes in version 0.3.5.3-alpha - 2018-10-17
   Tor 0.3.5.3-alpha fixes several bugs, mostly from previous 0.3.5.x
   versions. One important fix for relays addresses a problem with rate-
