@@ -1,14 +0,0 @@
-  o Security fixes:
-
-    - Try to leak less information about what relays a client is
-      choosing to a side-channel attacker.  Previously, a Tor client
-      would stop iterating through the list of available relays as
-      soon as it had chosen one, thus finishing a little earlier
-      when it picked a router earlier in the list.  If an attacker
-      can recover this timing information (nontrivial but not
-      proven to be impossible), they could learn some coarse-
-      grained information about which relays a client was picking
-      (middle nodes in particular are likelier to be affected than
-      exits).  The timing attack might be mitigated by other factors
-      (see bug #6537 for some discussion), but it's best not to
-      take chances.  Fixes bug 6537; bugfix on 0.0.8rc1.
