+Changes in version 0.2.6.7 - 2015-04-06
+  Tor 0.2.6.7 fixes two security issues that could be used by an
+  attacker to crash hidden services, or crash clients visiting hidden
+  services. Hidden services should upgrade as soon as possible; clients
+  should upgrade whenever packages become available.
+
+  This release also contains two simple improvements to make hidden
+  services a bit less vulnerable to denial-of-service attacks.
+
+  o Major bugfixes (security, hidden service):
+    - Fix an issue that would allow a malicious client to trigger an
+      assertion failure and halt a hidden service. Fixes bug 15600;
+      bugfix on 0.2.1.6-alpha. Reported by "skruffy".
+    - Fix a bug that could cause a client to crash with an assertion
+      failure when parsing a malformed hidden service descriptor. Fixes
+      bug 15601; bugfix on 0.2.1.5-alpha. Found by "DonnCha".
+
+  o Minor features (DoS-resistance, hidden service):
+    - Make it harder for attackers to overwhelm hidden services with
+      introductions, by blocking multiple introduction requests on the
+      same circuit. Resolves ticket #15515.
+    - Decrease the amount of reattempts that a hidden service is willing
+      to perform when its rendezvous circuits fail. This reduces the
+      computational cost for hidden service under heavy load. Resolves
+      ticket #11447.
