 Changes in version 0.3.1.1-alpha - 2017-??-??
 
 
+Changes in version 0.2.8.13 - 2017-03-03
+  Tor 0.2.8.13 backports a security fix from later Tor
+  releases.  Anybody running Tor 0.2.8.12 or earlier should upgrade to this
+  this release, if for some reason they cannot upgrade to a later
+  release series, and if they build Tor with the --enable-expensive-hardening
+  option.
+
+  Note that support for Tor 0.2.8.x is ending next year: we will not issue
+  any fixes for the Tor 0.2.8.x series after 1 Jan 2018.  If you need
+  a Tor release series with longer-term support, we recommend Tor 0.2.9.x.
+
+  o Major bugfixes (parsing, backported from 0.3.0.4-rc):
+    - Fix an integer underflow bug when comparing malformed Tor
+      versions. This bug could crash Tor when built with
+      --enable-expensive-hardening, or on Tor 0.2.9.1-alpha through Tor
+      0.2.9.8, which were built with -ftrapv by default. In other cases
+      it was harmless. Part of TROVE-2017-001. Fixes bug 21278; bugfix
+      on 0.0.8pre1. Found by OSS-Fuzz.
+
+  o Minor features (geoip):
+    - Update geoip and geoip6 to the February 8 2017 Maxmind GeoLite2
+      Country database.
+
+
+Changes in version 0.2.7.7 - 2017-03-03
+  Tor 0.2.7.7 backports a number of security fixes from later Tor
+  releases.  Anybody running Tor 0.2.7.6 or earlier should upgrade to
+  this release, if for some reason they cannot upgrade to a later
+  release series.
+
+  Note that support for Tor 0.2.7.x is ending this year: we will not issue
+  any fixes for the Tor 0.2.7.x series after 1 August 2017.  If you need
+  a Tor release series with longer-term support, we recommend Tor 0.2.9.x.
+
+  o Directory authority changes (backport from 0.2.8.5-rc):
+    - Urras is no longer a directory authority. Closes ticket 19271.
+
+  o Directory authority changes (backport from 0.2.9.2-alpha):
+    - The "Tonga" bridge authority has been retired; the new bridge
+      authority is "Bifroest". Closes tickets 19728 and 19690.
+
+  o Directory authority key updates (backport from 0.2.8.1-alpha):
+    - Update the V3 identity key for the dannenberg directory authority:
+      it was changed on 18 November 2015. Closes task 17906. Patch
+      by "teor".
+
+  o Major bugfixes (parsing, security, backport from 0.2.9.8):
+    - Fix a bug in parsing that could cause clients to read a single
+      byte past the end of an allocated region. This bug could be used
+      to cause hardened clients (built with --enable-expensive-hardening)
+      to crash if they tried to visit a hostile hidden service. Non-
+      hardened clients are only affected depending on the details of
+      their platform's memory allocator. Fixes bug 21018; bugfix on
+      0.2.0.8-alpha. Found by using libFuzzer. Also tracked as TROVE-
+      2016-12-002 and as CVE-2016-1254.
+
+  o Major bugfixes (security, client, DNS proxy, backport from 0.2.8.3-alpha):
+    - Stop a crash that could occur when a client running with DNSPort
+      received a query with multiple address types, and the first
+      address type was not supported. Found and fixed by Scott Dial.
+      Fixes bug 18710; bugfix on 0.2.5.4-alpha.
+    - Prevent a class of security bugs caused by treating the contents
+      of a buffer chunk as if they were a NUL-terminated string. At
+      least one such bug seems to be present in all currently used
+      versions of Tor, and would allow an attacker to remotely crash
+      most Tor instances, especially those compiled with extra compiler
+      hardening. With this defense in place, such bugs can't crash Tor,
+      though we should still fix them as they occur. Closes ticket
+      20384 (TROVE-2016-10-001).
+
+  o Major bugfixes (security, pointers, backport from 0.2.8.2-alpha):
+    - Avoid a difficult-to-trigger heap corruption attack when extending
+      a smartlist to contain over 16GB of pointers. Fixes bug 18162;
+      bugfix on 0.1.1.11-alpha, which fixed a related bug incompletely.
+      Reported by Guido Vranken.
+
+  o Major bugfixes (dns proxy mode, crash, backport from 0.2.8.2-alpha):
+    - Avoid crashing when running as a DNS proxy. Fixes bug 16248;
+      bugfix on 0.2.0.1-alpha. Patch from "cypherpunks".
+
+  o Major bugfixes (key management, backport from 0.2.8.3-alpha):
+    - If OpenSSL fails to generate an RSA key, do not retain a dangling
+      pointer to the previous (uninitialized) key value. The impact here
+      should be limited to a difficult-to-trigger crash, if OpenSSL is
+      running an engine that makes key generation failures possible, or
+      if OpenSSL runs out of memory. Fixes bug 19152; bugfix on
+      0.2.1.10-alpha. Found by Yuan Jochen Kang, Suman Jana, and
+      Baishakhi Ray.
+
+  o Major bugfixes (parsing, backported from 0.3.0.4-rc):
+    - Fix an integer underflow bug when comparing malformed Tor
+      versions. This bug could crash Tor when built with
+      --enable-expensive-hardening, or on Tor 0.2.9.1-alpha through Tor
+      0.2.9.8, which were built with -ftrapv by default. In other cases
+      it was harmless. Part of TROVE-2017-001. Fixes bug 21278; bugfix
+      on 0.0.8pre1. Found by OSS-Fuzz.
+
+  o Minor features (security, memory erasure, backport from 0.2.8.1-alpha):
+    - Make memwipe() do nothing when passed a NULL pointer or buffer of
+      zero size. Check size argument to memwipe() for underflow. Fixes
+      bug 18089; bugfix on 0.2.3.25 and 0.2.4.6-alpha. Reported by "gk",
+      patch by "teor".
+
+  o Minor features (bug-resistance, backport from 0.2.8.2-alpha):
+    - Make Tor survive errors involving connections without a
+      corresponding event object. Previously we'd fail with an
+      assertion; now we produce a log message. Related to bug 16248.
+
+  o Minor features (geoip):
+    - Update geoip and geoip6 to the February 8 2017 Maxmind GeoLite2
+      Country database.
+
+
+Changes in version 0.2.6.11 - 2017-03-03
+  Tor 0.2.6.11 backports a number of security fixes from later Tor
+  releases.  Anybody running Tor 0.2.6.10 or earlier should upgrade to
+  this release, if for some reason they cannot upgrade to a later
+  release series.
+
+  Note that support for Tor 0.2.6.x is ending this year: we will not issue
+  any fixes for the Tor 0.2.6.x series after 1 August 2017.  If you need
+  a Tor release series with longer-term support, we recommend Tor 0.2.9.x.
+
+  o Directory authority changes (backport from 0.2.8.5-rc):
+    - Urras is no longer a directory authority. Closes ticket 19271.

+
+  o Directory authority key updates (backport from 0.2.8.1-alpha):
+    - Update the V3 identity key for the dannenberg directory authority:
+      it was changed on 18 November 2015. Closes task 17906. Patch
+      by "teor".
+
+  o Major features (security fixes, backport from 0.2.9.4-alpha):
+    - Prevent a class of security bugs caused by treating the contents
+      of a buffer chunk as if they were a NUL-terminated string. At
+      least one such bug seems to be present in all currently used
+      versions of Tor, and would allow an attacker to remotely crash

+      Fixes bug 18710; bugfix on 0.2.5.4-alpha.
+
+  o Major bugfixes (security, correctness, backport from 0.2.7.4-rc):
+    - Fix an error that could cause us to read 4 bytes before the
+      beginning of an openssl string. This bug could be used to cause
+      Tor to crash on systems with unusual malloc implementations, or
+      systems with unusual hardening installed. Fixes bug 17404; bugfix
+      on 0.2.3.6-alpha.
+
+  o Major bugfixes (security, pointers, backport from 0.2.8.2-alpha):

+      bugfix on 0.2.0.1-alpha. Patch from "cypherpunks".
+
+  o Major bugfixes (guard selection, backport from 0.2.7.6):
+    - Actually look at the Guard flag when selecting a new directory
+      guard. When we implemented the directory guard design, we
+      accidentally started treating all relays as if they have the Guard
+      flag during guard selection, leading to weaker anonymity and worse
+      performance. Fixes bug 17772; bugfix on 0.2.4.8-alpha. Discovered
+      by Mohsen Imani.
+
+  o Major bugfixes (key management, backport from 0.2.8.3-alpha):

+
+

+    - Check for failures from crypto_early_init, and refuse to continue.
+      A previous typo meant that we could keep going with an
+      uninitialized crypto library, and would have OpenSSL initialize
+      its own PRNG. Fixes bug 16360; bugfix on 0.2.5.2-alpha, introduced

+      bugfix on 0.2.0.1-alpha. Patch from "cypherpunks".
+
+  o Major bugfixes (guard selection, backport from 0.2.7.6):
+    - Actually look at the Guard flag when selecting a new directory
+      guard. When we implemented the directory guard design, we
+      accidentally started treating all relays as if they have the Guard
+      flag during guard selection, leading to weaker anonymity and worse
+      performance. Fixes bug 17772; bugfix on 0.2.4.8-alpha. Discovered
+      by Mohsen Imani.
+
+  o Major bugfixes (key management, backport from 0.2.8.3-alpha):
+    - If OpenSSL fails to generate an RSA key, do not retain a dangling
+      pointer to the previous (uninitialized) key value. The impact here
+      should be limited to a difficult-to-trigger crash, if OpenSSL is
+      running an engine that makes key generation failures possible, or
+      if OpenSSL runs out of memory. Fixes bug 19152; bugfix on
+      0.2.1.10-alpha. Found by Yuan Jochen Kang, Suman Jana, and
+      Baishakhi Ray.
+
+  o Major bugfixes (parsing, backported from 0.3.0.4-rc):
+    - Fix an integer underflow bug when comparing malformed Tor
+      versions. This bug could crash Tor when built with
+      --enable-expensive-hardening, or on Tor 0.2.9.1-alpha through Tor
+      0.2.9.8, which were built with -ftrapv by default. In other cases
+      it was harmless. Part of TROVE-2017-001. Fixes bug 21278; bugfix
+      on 0.0.8pre1. Found by OSS-Fuzz.
+
+  o Minor features (security, memory erasure, backport from 0.2.8.1-alpha):
+    - Make memwipe() do nothing when passed a NULL pointer or buffer of
+      zero size. Check size argument to memwipe() for underflow. Fixes
+      bug 18089; bugfix on 0.2.3.25 and 0.2.4.6-alpha. Reported by "gk",
+      patch by "teor".
+
+  o Minor features (bug-resistance, backport from 0.2.8.2-alpha):
+    - Make Tor survive errors involving connections without a
+      corresponding event object. Previously we'd fail with an
+      assertion; now we produce a log message. Related to bug 16248.
+
+  o Minor features (DoS-resistance, backport from 0.2.7.1-alpha):
+    - Make it harder for attackers to overload hidden services with
+      introductions, by blocking multiple introduction requests on the
+      same circuit. Resolves ticket 15515.
+
+  o Minor features (geoip):
+    - Update geoip and geoip6 to the February 8 2017 Maxmind GeoLite2
+      Country database.
+
+  o Minor bugfixes (compilation, backport from 0.2.7.6):
+    - Fix a compilation warning with Clang 3.6: Do not check the
+      presence of an address which can never be NULL. Fixes bug 17781.
+
+  o Minor bugfixes (hidden service, backport from 0.2.7.1-alpha):
+    - Fix an out-of-bounds read when parsing invalid INTRODUCE2 cells on
+      a client authorized hidden service. Fixes bug 15823; bugfix
+      on 0.2.1.6-alpha.
