* (Merged the 0.5-pre branch back into CVS HEAD)
    * Replaced the old tunnel routing crypto with the one specified in
      router/doc/tunnel-alt.html, including updates to the web console to view
      and tweak it.
    * Provide the means for routers to reject tunnel requests with a wider
      range of responses:
        probabalistic rejection, due to approaching overload
        transient rejection, due to temporary overload
        bandwidth rejection, due to persistent bandwidth overload
        critical rejection, due to general router fault (or imminent shutdown)
      The different responses are factored into the profiles accordingly.
    * Replaced the old I2CP tunnel related options (tunnels.depthInbound, etc)
      with a series of new properties, relevent to the new tunnel routing code:
        inbound.nickname (used on the console)
        inbound.quantity (# of tunnels to use in any leaseSets)
        inbound.backupQuantity (# of tunnels to keep in the ready)
        inbound.length (# of remote peers in the tunnel)
        inbound.lengthVariance (if > 0, permute the length by adding a random #
                                up to the variance.  if < 0, permute the length
                                by adding or subtracting a random # up to the
                                variance)
        outbound.* (same as the inbound, except for the, uh, outbound tunnels
                    in that client's pool)
      There are other options, and more will be added later, but the above are
      the most relevent ones.
    * Replaced Jetty 4.2.21 with Jetty 5.1.2
    * Compress all profile data on disk.
    * Adjust the reseeding functionality to work even when the JVM's http proxy
      is set.
    * Enable a poor-man's interactive-flow in the streaming lib by choking the
      max window size.
    * Reduced the default streaming lib max message size to 16KB (though still
      configurable by the user), also doubling the default maximum window
      size.
    * Replaced the RouterIdentity in a Lease with its SHA256 hash.
    * Reduced the overall I2NP message checksum from a full 32 byte SHA256 to
      the first byte of the SHA256.
    * Added a new "netId" flag to let routers drop references to other routers
      who we won't be able to talk to.
    * Extended the timestamper to get a second (or third) opinion whenever it
      wants to actually adjust the clock offset.
    * Replaced that kludge of a timestamp I2NP message with a full blown
      DateMessage.
    * Substantial memory optimizations within the router and the SDK to reduce
      GC churn.  Client apps and the streaming libs have not been tuned,
      however.
    * More bugfixes thank you can shake a stick at.

2005-02-13  jrandom
    * Updated jbigi source to handle 64bit CPUs.  The bundled jbigi.jar still
      only contains 32bit versions, so build your own, placing libjbigi.so in
      your install dir if necessary.  (thanks mule!)
    * Added support for libjbigi-$os-athlon64 to NativeBigInteger and CPUID
      (thanks spaetz!)
