- Allow at least 3 packets and up to half the window to be active resends
     instead of just 1, to reduce stall time after a packet drop
   - Increase fast retransmit threshold back to 3 to reduce retransmissions
   - Don't fast retransmit if we recently retransmitted it already
   - Allow double the window as long as gaps are less than the window
   - Don't set the MSS in a resent packet (saves 2 bytes)
   - Remove redundant calls to updateAcks()
   - Update activity timer when resending a packet
   - Reset unackedPacketsReceived counter at all places where acks are sent
     so it isn't wrong
   - Fix some places where the activeResends count could become wrong
   - Prevent storm of CLOSE packets
   - Never resend the whole packet in ackImmediately(), just send an ack
   - Cancel flusher timer in MessageOutputStream when closed
   - Move some createRateStats to ConnectionManager to reduce repeated calls
   - Cleanups, javadocs, logging, volatile, finals

             TrackerClient holds on to the old one and that causes it
             to not get peers. Possibly fixes ticket #563.

resulting in trailing zeros after the random padding in the unencrypted AES data block.
The number of zeros equaled the number of tags included (typ. 6 or 40).
As the data size is rounded up to the next multiple of 16,
this increased the size of the data by 0, 16, 32, or 48 bytes when tags were included.
Bug introduced 2004-10-30.

 * Transport: Add Ethiopia to hidden mode list
 * Log and javadoc tweaks

               streaming messages don't get split up unnecessarily

         increase max (could have caused "local loopback" problems)

   - Greatly simplify the VerifyUsage timers
   - Constructor cleanup

 * I2PTunnel: More javadoc warnings on default options

   - Listen only on local port if set
   - Listen only for streaming protocol if configured (new option)
   - Javadocs re: ports

   - Improve torrent shutdown handling to maximize chance of
     announces getting to tracker
   - Clean up delete-torrent messages
   - Remove redundant shutdown hook
   - Avoid NPE in PEX message handling
   - Log tweaks

          anonymity while preserving the ability to monitor
          the network (effective next release)

   - More client options cleanups
   - Options changes now propagate to running
     socket managers and sessions, and through to the router
 * SocketManager:
   - Simplify factory, use 4-arg constructor,
     make fields final, deprecate 0-arg constructor
   - Improve how options are updated
   - Javadocs

 * I2PTunnel:
   - Don't strip port from an I2P URL

   - Channel cleanups and comments
   - New I2PSocketAddress

 * I2PTunnel:
   - Pass port through HTTP client proxy
   - HTTP server proxy sets host header to
     the value of "spoofedhost.xx" option for port xx
   - Set client options more efficiently

   - Reduce TrackerClient threads
   - Reduce delay between peer adds for faster startup
   - Thread the announces and reduce timeout when stopping

   - Display torrent file downloads in torrent area
   - Sort magnets and downloads first
   - Fix sorting problem when torrent dir is a symlink
   - Reduce max file idle time
   - arrow_down icon copied from console css

   - Move private tracker config from create box to torrent config
   - Refactor private and open tracker configuration
   - Add private indication on details page
