+Changes in version 0.2.7.6 - 2015-12-10
+  Tor version 0.2.7.6 fixes a major bug in entry guard selection, as
+  well as a minor bug in hidden service reliability.
+
+  o Major bugfixes (guard selection):
+    - 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 17222; bugfix on 0.2.4.8-alpha. Discovered
+      by Mohsen Imani.
+
+  o Minor features (geoip):
+    - Update geoip and geoip6 to the December 1 2015 Maxmind GeoLite2
+      Country database.
+
+  o Minor bugfixes (compilation):
+    - When checking for net/pfvar.h, include netinet/in.h if possible.
+      This fixes transparent proxy detection on OpenBSD. Fixes bug
+      17551; bugfix on 0.1.2.1-alpha. Patch from "rubiate".
+    - 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 (correctness):
+    - When displaying an IPv6 exit policy, include the mask bits
+      correctly even when the number is greater than 31. Fixes bug
+      16056; bugfix on 0.2.4.7-alpha. Patch from "gturner".
+    - The wrong list was used when looking up expired intro points in a
+      rend service object, causing what we think could be reachability
+      issues for hidden services, and triggering a BUG log. Fixes bug
+      16702; bugfix on 0.2.7.2-alpha.
+    - Fix undefined behavior in the tor_cert_checksig function. Fixes
+      bug 17722; bugfix on 0.2.7.2-alpha.
