+
+Changes in version 0.2.5.11 - 2015-03-17
+  Tor 0.2.5.11 is the second stable release in the 0.2.5 series.
+
+  It backports several bugfixes from the 0.2.6 branch, including a
+  couple of medium-level security fixes for relays and exit nodes.
+  It also updates the list of directory authorities.
+
+  o Directory authority changes:
+    - Remove turtles as a directory authority.
+    - Add longclaw as a new (v3) directory authority. This implements
+      ticket 13296. This keeps the directory authority count at 9.
+    - The directory authority Faravahar has a new IP address. This
+      closes ticket 14487.
+
+  o Major bugfixes (crash, OSX, security):
+    - Fix a remote denial-of-service opportunity caused by a bug in
+      OSX's _strlcat_chk() function. Fixes bug 15205; bug first appeared
+      in OSX 10.9.
+
+  o Major bugfixes (relay, stability, possible security):
+    - Fix a bug that could lead to a relay crashing with an assertion
+      failure if a buffer of exactly the wrong layout was passed to
+      buf_pullup() at exactly the wrong time. Fixes bug 15083; bugfix on
+      0.2.0.10-alpha. Patch from 'cypherpunks'.
+    - Do not assert if the 'data' pointer on a buffer is advanced to the
+      very end of the buffer; log a BUG message instead. Only assert if
+      it is past that point. Fixes bug 15083; bugfix on 0.2.0.10-alpha.
+
+  o Major bugfixes (exit node stability):
+    - Fix an assertion failure that could occur under high DNS load.
+      Fixes bug 14129; bugfix on Tor 0.0.7rc1. Found by "jowr";
+      diagnosed and fixed by "cypherpunks".
+
+  o Major bugfixes (Linux seccomp2 sandbox):
+    - Upon receiving sighup with the seccomp2 sandbox enabled, do not
+      crash during attempts to call wait4. Fixes bug 15088; bugfix on
+      0.2.5.1-alpha. Patch from "sanic".
+
+  o Minor features (controller):
+    - New "GETINFO bw-event-cache" to get information about recent
+      bandwidth events. Closes ticket 14128. Useful for controllers to
+      get recent bandwidth history after the fix for ticket 13988.
+
+  o Minor features (geoip):
+    - Update geoip to the March 3 2015 Maxmind GeoLite2 Country database.
+    - Update geoip6 to the March 3 2015 Maxmind GeoLite2
+      Country database.
+
+  o Minor bugfixes (client, automapping):
+    - Avoid crashing on torrc lines for VirtualAddrNetworkIPv[4|6] when
+      no value follows the option. Fixes bug 14142; bugfix on
+      0.2.4.7-alpha. Patch by "teor".
+    - Fix a memory leak when using AutomapHostsOnResolve. Fixes bug
+      14195; bugfix on 0.1.0.1-rc.
+
+  o Minor bugfixes (compilation):
+    - Build without warnings with the stock OpenSSL srtp.h header, which
+      has a duplicate declaration of SSL_get_selected_srtp_profile().
+      Fixes bug 14220; this is OpenSSL's bug, not ours.
+
+  o Minor bugfixes (directory authority):
+    - Allow directory authorities to fetch more data from one another if
+      they find themselves missing lots of votes. Previously, they had
+      been bumping against the 10 MB queued data limit. Fixes bug 14261;
+      bugfix on 0.1.2.5-alpha.
+    - Enlarge the buffer to read bwauth generated files to avoid an
+      issue when parsing the file in dirserv_read_measured_bandwidths().
+      Fixes bug 14125; bugfix on 0.2.2.1-alpha.
+
+  o Minor bugfixes (statistics):
+    - Increase period over which bandwidth observations are aggregated
+      from 15 minutes to 4 hours. Fixes bug 13988; bugfix on 0.0.8pre1.
+
+  o Minor bugfixes (preventative security, C safety):
+    - When reading a hexadecimal, base-32, or base-64 encoded value from
+      a string, always overwrite the whole output buffer. This prevents
+      some bugs where we would look at (but fortunately, not reveal)
+      uninitialized memory on the stack. Fixes bug 14013; bugfix on all
+      versions of Tor.
+
+
+Changes in version 0.2.4.26 - 2015-03-17
+  Tor 0.2.4.26 includes an updated list of directory authorities.  It
+  also backports a couple of stability and security bugfixes from 0.2.5

+
+  o Major bugfixes (exit node stability, also in 0.2.6.3-alpha):

+      Fixes bug 14129; bugfix on Tor 0.0.7rc1. Found by "jowr";
+      diagnosed and fixed by "cypherpunks".
+
+  o Major bugfixes (relay, stability, possible security, also in 0.2.6.4-rc):

+      failure if a buffer of exactly the wrong layout was passed to
+      buf_pullup() at exactly the wrong time. Fixes bug 15083; bugfix on
