* Within the tunnel, use xor(IV, msg[0:16]) as the flag to detect dups,
      rather than the IV by itself, preventing an attack that would let
      colluding internal adversaries tag a message to determine that they are
      in the same tunnel.  Thanks dvorak for the catch!
    * Drop long inactive profiles on startup and shutdown
    * /configstats.jsp: web interface to pick what stats to log
    * Deliver more session tags to account for wider window sizes
    * Cache some intermediate values in our HMACSHA256 and BC's HMAC
    * Track the client send rate (stream.sendBps and client.sendBpsRaw)
    * UrlLauncher: adjust the browser selection order
    * I2PAppContext: hooks for dummy HMACSHA256 and a weak PRNG
    * StreamSinkClient: add support for sending an unlimited amount of data
    * Migrate the tests out of the default build jars

2005-06-22  Comwiz
    * Migrate the core tests to junit
