 Changes in version 0.2.8.2-alpha - 2016-03-??
   Tor 0.2.8.2-alpha is the second alpha in its series. It fixes numerous
   bugs in earlier versions of Tor, including some that prevented

       bugfix on Tor 0.1.1.11-alpha, which fixed a related bug
       incompletely. Reported by Guido Vranken.
 
+  o Major bugfixes (bridges, pluggable transports):
+    - Modify the check for OR connections to private addresses. Allow
+      bridges on private addresses, including pluggable transports that
+      ignore the (potentially private) address in the bridge line. Fixes
+      bug 18517; bugfix on 0.2.8.1-alpha. Reported by "gk", patch
+      by "teor".
+
+  o Major bugfixes (compilation):
+    - Repair hardened builds under the clang compiler. Previously, our
+      use of _FORTIFY_SOURCE would conflict with clang's address
+      sanitizer. Fixes bug 14821; bugfix on 0.2.5.4-alpha.
+
+  o Major bugfixes (crash on shutdown):
+    - Fix a segfault during startup: If Unix domain socket was
+      configured as listener (such as a ControlSocket or a SocksPort
+      "unix:" socket), and tor was started as root but not configured to
+      switch to another user, tor would segfault while trying to string
+      compare a NULL value. Fixes bug 18261; bugfix on 0.2.8.1-alpha.

+    - Correctly handle detaching circuits from muxes when shutting down.
+      Fixes bug 18116; bugfix on 0.2.8.1-alpha.
+    - Fix an assert-on-exit bug related to counting memory usage in
+      rephist.c. Fixes bug 18651; bugfix on 0.2.8.1-alpha.

+  o Major bugfixes (dns proxy mode, crash):
+    - Avoid crashing when running as a DNS proxy. Fixes bug 16248;
