* Enabled SSU as the default top priority transport, adjusting the
config.jsp page accordingly.
* Add verification fields to the SSU and TCP connection negotiation (not
compatible with previous builds)
* Enable the backwards incompatible tunnel crypto change as documented in
tunnel-alt.html (have each hop encrypt the received IV before using it,
then encrypt it again before sending it on)
* Disable the I2CP encryption, leaving in place the end to end garlic
encryption (another backwards incompatible change)
* Adjust the protocol versions on the TCP and SSU transports so that they
won't talk to older routers.
* Fix up the config stats handling again
* Fix a rare off-by-one in the SSU fragmentation
* Reduce some unnecessary netDb resending by inluding the peers queried
successfully in the store redundancy count.
* More fixes for the I2PTunnel "other" interface handling (thanks nelgin!)
* Add back the code to handle bids from multiple transports (though there
is still only one transport enabled by default)
* Adjust the router's queueing of outbound client messages when under
heavy load by running the preparatory job in the client's I2CP handler
thread, thereby blocking additional outbound messages when the router is
hosed.
* No need to validate or persist a netDb entry if we already have it
And for some udp stuff:
* only bid on what we know (duh)
* reduceed the queue size in the UDPSender itself, so that ACKs go
through more quickly, leaving the payload messages to queue up in
the outbound fragment scheduler
* rather than /= 2 on congestion, /= 2/3 (still AIMD, but less drastic)
* adjust the fragment selector so a wsiz throttle won't force extra
volleys
* mark congestion when it occurs, not after the message has been
ACKed
* when doing a round robin over the active messages, move on to the
next after a full volley, not after each packet (causing less "fair"
performance but better latency)
* reduced the lock contention in the inboundMessageFragments by
moving the ack and complete queues to the ACKSender and
MessageReceiver respectively (each of which have their own
threads)
* prefer new and existing UDP sessions to new TCP sessions, but
prefer existing TCP sessions to new UDP sessions
* Implemented the news fetch / update policy code, as configurated on
/configupdate.jsp. Defaults are to grab the news every 24h (or if it
doesn't exist yet, on startup). No action is taken however, though if
the news.xml specifies that a new release is available, an option to
update will be shown on the router console.
* New initialNews.xml delivered with new installs, and moved news.xml out
of the i2pwww module and into the i2p module so that we can bundle it
within each update.
