   Tor 0.4.1.2-alpha resolves numerous bugs--some of them from the
   previous alpha, and some much older. It also contains minor testing
   improvements, and an improvement to the security of our authenticated

-  o Major bugfixes (Flow Control, SENDME):
-    - The decrement of the stream-level package window was done in a
-      log_debug() statement meaning that if the debug logs were not
-      enabled, the decrement would never happen and thus the window
-      would be out of sync with the other end point. Fixes bug 30628;

   o Minor features (authenticated SENDME):
     - Ensure that there is enough randomness on every circuit to prevent

-      will need to send: at a random interval, if we have not send

-      that we can fill with random bytes. Closes ticket 26846.
