       can insert an extra string in the platform line by setting the
       preprocessor variable TOR_BUILD_TAG. Resolves bug 2988.
+    - Disable TLS session tickets. OpenSSL's implementation was giving

       before the first Tor release, in svn commit r152.
-    - Set the SO_REUSEADDR socket option before we call bind() on outgoing

-      bugfix on 0.2.2.26-beta.
     - Don't update the AccountingSoftLimitHitAt state file entry whenever
       tor gets started. This prevents a wrong average bandwidth
       estimate, which would cause relays to always start a new accounting
       interval at the earliest possible moment. Fixes bug 2003; bugfix
       on 0.2.2.7-alpha. Reported by Bryon Eldridge, who also helped
       immensely in tracking this bug down.
