+Changes in version 0.3.5.11 - 2020-07-09
+  Tor 0.3.5.11 backports fixes from later tor releases, including several
+  usability, portability, and reliability fixes.
+
+  This release also fixes TROVE-2020-001, a medium-severity denial of
+  service vulnerability affecting all versions of Tor when compiled with
+  the NSS encryption library. (This is not the default configuration.)
+  Using this vulnerability, an attacker could cause an affected Tor
+  instance to crash remotely. This issue is also tracked as CVE-2020-
+  15572. Anybody running a version of Tor built with the NSS library
+  should upgrade to 0.3.5.11, 0.4.2.8, 0.4.3.6, or 0.4.4.2-alpha
+  or later.
+
+  o Major bugfixes (NSS, security, backport from 0.4.4.2-alpha):
+    - Fix a crash due to an out-of-bound memory access when Tor is
+      compiled with NSS support. Fixes bug 33119; bugfix on
+      0.3.5.1-alpha. This issue is also tracked as TROVE-2020-001
+      and CVE-2020-15572.
+
+  o Major bugfixes (DoS defenses, bridges, pluggable transport, backport from 0.4.3.4-rc):
+    - Fix a bug that was preventing DoS defenses from running on bridges
+      with a pluggable transport. Previously, the DoS subsystem was not
+      given the transport name of the client connection, thus failed to
+      find the GeoIP cache entry for that client address. Fixes bug
+      33491; bugfix on 0.3.3.2-alpha.
+
+  o Minor features (testing, backport from 0.4.3.4-rc):
+    - The unit tests now support a "TOR_SKIP_TESTCASES" environment
+      variable to specify a list of space-separated test cases that
+      should not be executed. We will use this to disable certain tests
+      that are failing on Appveyor because of mismatched OpenSSL
+      libraries. Part of ticket 33643.
+
+  o Minor bugfix (CI, Windows, backport from 0.4.4.2-alpha):
+    - Use the correct 64-bit printf format when compiling with MINGW on
+      Appveyor. Fixes bug 40026; bugfix on 0.3.5.5-alpha.
+
+  o Minor bugfix (relay, configuration, backport from 0.4.3.3-alpha):
+    - Warn if the ContactInfo field is not set, and tell the relay
+      operator that not having a ContactInfo field set might cause their
+      relay to get rejected in the future. Fixes bug 33361; bugfix
+      on 0.1.1.10-alpha.
+
+  o Minor bugfixes (client performance, backport from 0.4.4.1-alpha):
+    - Resume use of preemptively-built circuits when UseEntryGuards is set
+      to 0. We accidentally disabled this feature with that config
+      setting, leading to slower load times. Fixes bug 34303; bugfix
+      on 0.3.3.2-alpha.
+
+  o Minor bugfixes (compiler compatibility, backport from 0.4.3.5):
+    - Avoid compiler warnings from Clang 10 related to the use of GCC-
+      style "/* falls through */" comments. Both Clang and GCC allow
+      __attribute__((fallthrough)) instead, so that's what we're using
+      now. Fixes bug 34078; bugfix on 0.3.1.3-alpha.
+
+  o Minor bugfixes (compiler warnings, backport from 0.4.4.2-alpha):
+    - Fix a compiler warning on platforms with 32-bit time_t values.
+      Fixes bug 40028; bugfix on 0.3.2.8-rc.
+
+  o Minor bugfixes (embedded Tor, backport from 0.4.3.1-alpha):
+    - When starting Tor any time after the first time in a process,
+      register the thread in which it is running as the main thread.
+      Previously, we only did this on Windows, which could lead to bugs
+      like 23081 on non-Windows platforms. Fixes bug 32884; bugfix
+      on 0.3.3.1-alpha.
+
+  o Minor bugfixes (key portability, backport from 0.4.3.4-rc):
+    - When reading PEM-encoded key data, tolerate CRLF line-endings even
+      if we are not running on Windows. Previously, non-Windows hosts
+      would reject these line-endings in certain positions, making
+      certain key files hard to move from one host to another. Fixes bug
+      33032; bugfix on 0.3.5.1-alpha.
+
+  o Minor bugfixes (logging, backport from 0.4.4.2-alpha):
+    - Downgrade a noisy log message that could occur naturally when
+      receiving an extrainfo document that we no longer want. Fixes bug
+      16016; bugfix on 0.2.6.3-alpha.
+
+  o Minor bugfixes (onion service v3, client, backport from 0.4.3.3-alpha):
+    - Remove a BUG() warning that would cause a stack trace if an onion
+      service descriptor was freed while we were waiting for a
+      rendezvous circuit to complete. Fixes bug 28992; bugfix
+      on 0.3.2.1-alpha.
+
+  o Testing (CI, backport from 0.4.3.4-rc):
+    - In our Appveyor Windows CI, copy required DLLs to test and app
+      directories, before running tor's tests. This ensures that tor.exe
+      and test*.exe use the correct version of each DLL. This fix is not
+      required, but we hope it will avoid DLL search issues in future.
+      Fixes bug 33673; bugfix on 0.3.4.2-alpha.
+    - On Appveyor, skip the crypto/openssl_version test, which is
+      failing because of a mismatched library installation. Fix
+      for 33643.
