Sun Jan 11 19:24:27 CET 2005
        gnunet-gtk now resumes aborted downloads automatically.

Sun Nov 14 16:49:02 EST 2004
	Debugged collections, seems to work (not that it looks pretty,
	but it basically works, the rest is UI work).  Fixed deadlock
	in gnunet-gtk logging.  Releasing GNUnet 0.6.5.

Thu Nov  4 09:04:48 EST 2004
	Added (highly experimental) support for collections.

	Releasing GNUnet 0.6.4.

Tue Aug 24 20:59:14 IST 2004
	Significant enhancements to namespaces.  A namespace can
	now be annotated with meta-data at the time that it is
	created.
	
Sat Aug 21 01:00:06 IST 2004
	Adding GNU gettext support to configure.
	
Thu Aug 19 01:26:55 IST 2004
	Migrating gnunet-gtk to GTK 2.0 (tested with 2.4).

Mon Aug 16 00:30:59 IST 2004
	Removed gcry.  Added dependency on GNU MP library (libgmp)
	for kblocks.

Tue Aug  3 17:57:43 IST 2004
	Fixed bugs in gnunet-update.  Fixed segfault in AFS startup.
	Fixed warnings in gnunet-peer-info/gnunetd.  Fixed packaging
	error (not all of util/gcry included in distribution).
	Releasing GNUnet 0.6.3a.

Mon Aug  2 20:06:07 IST 2004
	Releasing GNUnet 0.6.3.

Sun Aug  1 01:31:19 IST 2004
	Changed most places from HexName to the new, shorter EncName.
	Pushed URIs for namespaces and keyword searches into more
	widespread use.  Replaced all occurences of sprintf with
	SNPRINTF (to obtain extra bounds check).
	
Sun Jul 11 13:54:01 IST 2004
	Moved testcases for libgnunet_util to util/ directory.
	Made DB testcases in afs/module/ run for each available
	database and not just the one configured in /etc/gnunet.conf.

Fri Jun 25 21:05:59 IST 2004
	Releasing GNUnet 0.6.2b (resolves various minor bugs).

	Releasing GNUnet 0.6.2a (resolves libgcrypt and packageing
	issues, improved gtk-statistics, other minor bugfixes).
	
Fri Apr 30 21:36:23 EST 2004
	Fixed synchronization problem in cron (only relevant for
	parallel downloading).  Releasing GNUnet 0.6.2.

Mon Apr 26 21:13:45 EST 2004
	Added support to gnunet-check to convert file index database
	to new design.  Removed support for pre 0.6.1b bloomfilter
	conversion (would have been too messy to support both).
	Added old-version check to gnunetd startup to make updates
	more systematic in the future (not perfect, though).

Mon Apr 26 19:27:29 EST 2004
	Recursive insertion of directories with gnunet-gtk 
	now works including the progress bar.

Sun Apr 25 18:24:55 EST 2004
	Global changes to fix bug #698.  The fix is still 
	incomplete with respect to pthread.h specific structs.
	
Sun Apr 25 15:20:29 EST 2004
	Fixed compile error in IPv6 transports.

Fri Apr 23 23:38:01 EST 2004
	Added recursive insertion of directories to gnunet-gtk.
	Progress-bar does not work yet, also libextractor is
	always used (no option to turn it off).
	
Fri Apr 23 21:49:18 EST 2004
	Removed need to specify _protocol in configuration file
	(shorter is better).

Wed Apr 21 23:32:36 EST 2004
	Added code to bound priority used by clients by twice the
	average priority of requests from other peers that are 
	routed at the moment.  That prevents clients from exposing
	themselves with excessively high priorities (and also 
	avoids giving too much credit/trust needlessly).

Tue Apr 20 22:27:19 EST 2004
	Added possibility of using a link instead of making a copy
	if gnunetd and the insert-client both run on the same machine.

Tue Apr 20 00:00:58 EST 2004
	Added network transparency for indexing files (by copying
	them to a GNUnet(d) specific directory).  This breaks
	unindexing (for files indexed with previous versions) and
	forces the user to make a copy of the file.  In the near
	future we should resolve this problem by allowing the use
	of a link.

Sun Apr 18 17:24:34 EST 2004
	Adding recursive, parallel download of directories to
	gnunet-download

Sun Apr 18 01:57:32 EST 2004
	gnunet-transport-check can now be used to check
	external connectivity (with other peers).

Thu Jan 15 23:14:54 EST 2004
	Fixed size of super-bloomfilter (was factor of 32 to small).

	NAT transport passes tests.

Sat Dec 13 00:16:41 EST 2003
	Added NAT transport.

Thu Oct 16 19:20:29 EST 2003
	Added greedy knapsack heuristic for use by CPU-overloaded
	systems.

Mon Oct 13 22:36:45 EST 2003
	Improved gnunet-gtk code that forks of gnunetd (some extra checking,
	use fork-exec instead of system(), pass configuration file as
	argument).

Sun Oct 12 03:42:55 EST 2003
	Split bandwidth montoring into up and downstream.
	Why stop sending replies merely because we *receive* traffic!?
	Also reduced frequency of HELO exchange.
	Added more statistics (traffic by type).

Fri Oct 10 02:05:13 EST 2003
	Fixed bug that wasted a lot of CPU time.
	Better CPU usage control by making knapsack
	solving (frequency and problem size) dependent
	on CPU load.

Thu Oct  9 14:29:35 EST 2003
	Releasing 0.6.0a.

Sun Oct  5 21:35:23 EST 2003
	GNUnet 0.6.0 released.

Sat Oct  4 12:54:55 EST 2003
	Fixed bug in timer code (discovered in testcase).	
	Added extensive testcases for platform dependent code.

Fri Sep 19 01:38:00 EST 2003
	Added code to allow namespace queries to return multiple
	results.  Updates are now displayed in separate tabs.

Wed Sep 17 23:54:15 EST 2003
	Migrated libgcrypt code in util to comply with
	libgcrypt 1.1.43 (and it passes the tests just fine)

	GNUnet 0.5.5 released.

Tue Aug 12 20:48:39 EST 2003

Wed May 29 01:13:15 EST 2003
	Fixing some ugly bugs in connection.c that caused
	permanent connection-drop and connection-establish
	cycles (every 5 minutes).
	
Sat May 24 03:12:42 EST 2003
	Migrated subset of libgcrypt into GNUnet tree to use
	it instead of OpenSSL or libgcrypt.  RSA in the new
	code is broken at the moment.

Sun May 18 04:10:25 EST 2003
	GNUnet 0.5.4 released.

Sat May 10 21:39:35 EST 2003
	Only download hostlist after a while if we were
	not able to connect (to reduce load on hostlist
	servers).

Fri May  2 23:20:15 EST 2003
	Added code to handle massive collisions in datastore
	(thousands of files under the same keyword).

Sun Apr 27 23:52:12 EST 2003
	GNUnet 0.5.3 released.
	
Wed Apr 23 03:20:21 EST 2003
	Build system cleanup, location of mysql, gdbm, tdb and
	db can now be specified.

Mon Apr 21 01:54:24 EST 2003
	Made random content selection with pIdx faster
	(do not read entire pidx files) and fully random
	(added code to weigh pidx files by number of entries).

Sun Apr 20 23:25:45 EST 2003
	Fixed double-free in TCP transport code (seems to have
	only had a real chance to occur under BSD in practice).

Sat Apr 19 14:42:37 EST 2003
	Replaced use of dlopen for plugins with the more 
	portable ltdl from libtool.
	
Thu Apr 17 20:36:42 EST 2003
	Added synchronization to pIdx, also use truncate
	to remove last n entries instead of re-writing the
	entire file (much, much faster).
	
Mon Apr  7 00:00:07 EST 2003
	Implemented gnunet-delete.

Sat Apr  5 15:55:31 EST 2003
	Made directory database use 256 sub-directories 
	(should increase speed a lot, with the new DB
	manager, this will result in at most 2048
	files per directory).

Mon Mar 31 16:51:24 EST 2003
	gnunet-convert and gnunet-check compile again 
	with the new DB code.
	
Sun Mar 30 13:14:52 CET 2003

	Releasing 0.5.2a.

Sun Mar 16 20:24:24 EST 2003
	Caching of RSA signatures for HELOs reduced CPU
	usage dramatically, from an average of 31% to less 
	than 5% on my machine.

Sun Mar 16 01:21:16 EST 2003
	Fixed locking problem and problem with TCP transport
	(bad set of sockets in select).

Sat Mar 15 03:02:42 EST 2003
	Fixed bug that copied wrong content (garbage) into
	replies for other peers.  This one was introduced
	briefly before 0.5.2. Argh.

Fri Feb 28 00:23:02 EST 2003
	Fixed segfault in gnunet-gtk when closing search
	sub-window.

Thu Feb 27 16:23:20 EST 2003
	Releasing GNUnet 0.5.2.

Mon Feb 24 00:28:52 EST 2003
	Cleaning up the AFS routing code, also some tweaks
	to improve anonymity against an active attacker.

Thu Feb 20 23:51:30 EST 2003
	gnunet-tracekit works now nicely (and with dot).
	Also, GNUnet now attempts to locate a configuration
	file in /etc/gnunet.conf if ~/.gnunet/gnunet.conf
	does not exist (and nothing is specified on the
	command line).

Wed Feb 12 23:21:44 EST 2003
	Fixed deadlock between pingpong and connection
	module.

Tue Feb  4 13:22:09 EST 2003
	Releasing GNUnet 0.5.1(a).

Tue Feb  4 04:05:58 EST 2003
	RSA encryption of OpenSSL has been changed to pure
	PKCS #1 to achieve compatibility with libgcrypt.

Mon Feb  3 18:46:54 EST 2003
	RSA signature encoding has been changed from raw
	to PKCS #1 compatible encoding. This should help
	making the migration to libgcrypt easier in the
	future. RSA & libgcrypt are still not friends,
	but the GNUnet code should be mostly there.

Fri Jan 31 10:40:01 EST 2003
	gnunet-peer-info tool was added. This tool can
	prints information about all known peers and may
        be useful for diagnostics.

Mon Jan 20 17:54:51 EST 2003
	A large number of memory leaks got fixed thanks
	to the new automated scripts to find them.

Thu Jan 16 00:49:20 EST 2003
	Nearly finished removing dependencies on OpenSSL
	(using libgcrypt instead), $FOO-expansion in 
	configuration parsing and RSA (public key crypto) 
	are the only missing pieces.	

Mon Jan 13 01:53:45 EST 2003
	Fixed deadlock in gnunetd (would stop processing
	messages).

Sun Dec 27 13:34:11 CET 2002
	Fixed segmentation fault that occured when number
	of known peers goes over 128.
	
Sat Dec 21 16:27:11 CET 2002
        Releasing GNUnet 0.5.0.

Sat Dec 14 03:47:05 CET 2002  
	Bugfixes over bugfixes. Various memory leaks
	from gnunetd to gnunet-download, problems
	with bloomfilters and gnunet-check, enforcing
	storage limitations set by the user, fixes
	in the UDP, TCP and SMTP transports; 
	better thread termination (avoid asynchronous
	cancellation). Not to mention the new
	tools gnunet-transport-check and gnunet-tbench
	for the evaulation of correctness and performance
	of the transport services. 

Wed Nov  6 22:49:24 EST 2002
	Added load smoothing for network and CPU load
	such that we quickly adapt to increasing load,
	but slowly reduce the (effective) load value
	used in the policy if the load drops. This should
	help avoiding 0-1 policies where we always jump
	up and down between 100% load and no load, letting
	in one period all traffic through and in the next
	none. 

Wed Nov  6 00:31:39 EST 2002
	Added port==0 for UDP and TCP transport as an
	option to indicate that the transport is to be
	used only to establish connections to other
	peers but not as a server-socket (that is,
	if the port is 0, other GNUnet peers can not
	connect to the local node's UDP or TCP port,
	but the local node can still use UDP 
	(unidirectional) or TCP (even bi-directional)
	to talk to other peers. This is useful if a
	node is behind a NAT box and can not receive
	inbound traffic but is able to send messages to
	other peers (and in the case of TCP even receive
	messages if the local peer initiated the
	bi-directional connection). Currently, a peer
	must always provide at least one transport under
	which the peer can be "actively" reached since
	otherwise other peers will not keep the public
	key of that peer and thus not be able to 
	complete the session key exchange. For NAT-box
	peers, SMTP might be a viable choice for that
	"active" protocol. 

Fri Oct 11 02:16:42 EST 2002
	Added bloomfilter interface and calls to the BF from 
	the AFS service implementation. Missing for working
	bloomfilter are calls from gnunet-insert to update
	the bloom-filter (top-CHK and super-queries) and the
	actual bloom-filter implementation.
	
Tue Oct  8 20:35:45 EST 2002
	TCP transport now works with only one thread (using
	select) instead of one thread per peer-connection.

Fri Sep 27 02:24:52 EST 2002
	New content encoding (still only 1k blocks, but with
	CHK style IBocks and GBlocks for aggressive content 
	migration) now seems to work.

Mon Sep 16 01:57:55 EST 2002
	Implemented gnunet-chat, a demo-application for
	how to develop p2p applications on top of GNUnet.

Sun Sep 15 22:48:28 EST 2002
	Fixing (long standing) problem with segfaults under BSD
	due to stack overflow in threads.

Sun Sep 15 02:04:52 EST 2002
	TCP transport layer implementation seems to work now.
	gnunet.conf is now documented on the web. HELO exchange
        is fixed, so is the CS-connection whitelisting.

Fri Sep 13 00:51:01 EST 2002
	Update on the progress towards 0.4.9. What is missing?
        * new content encoding to facilitate:
          - content migration
          - discriminated routing (downloads vs. searches)
          - variable blocksize (?)
          - self-synchronizing stream encoding (?)
        * additional transport layers (SMTP, TCP, HTTP)
        * demo application (chat) for how to use the API
        * documentation on new gnunet.conf
        * known bugs:
          - Igor reports, HELO exchange is broken
          - David reports, CS-connection whitelisting is broken
          - rpm.spec is outdated (add GNUnet's dynamic libraries)

	What has been resolved so far:
        Major:
        * transport and application layer have been abstracted
        * dynamic loading of transports and applications is
          implemented
        * routing much faster since slots are freed earlier
        * querymanager is more intelligent in where to send 
          queries (presumably, not tested)

        Refactoring:
        * configuration can store options from commandline
        * statistics is totally dynamic and can be extended
        * connection buffer does callbacks on applications to
          fill buffers with queries instead of noise, and
          the querymanager makes use of this

        Moving:
        * common/ is gone
        * gnettypes.h is gone
        * AFS specific code is all in AFS
        * renaming is also done

Sun Aug 25 15:30:56 EST 2002
	Moving work towards 0.4.9 to CVS. The major goals are:
	* independent transport layer (UDP, TCP, SMTP, HTTP,
	  any of these should be possible in the future); also,
	  the MTU may be defined differently by any one of them.
	* independent application layer. Anonymous File Sharing
	  (AFS) should just be one application for the GNUnet
	  core.

	Other minor goals and refactorings include:
	* configuration - we should be able to update dynamically
	  options from the gnunet.conf file. E.g. by adding options
	  from the command line
	* statistics - we should not have a hardwired fixed set
	  of datapoints, the statistics module should be useful
	  for any kind of statistics
	* noise reduction - the connection buffer should allow
	  the use of intelligent applications that get notified
	  if noise would be send and then can plug in useful data

	And then there is just moving stuff:
	* move "common/" to where it belongs (either applications
	  or server)
	* gnettypes is bad if we want to seperate app specifcs
	  and core. The typedefs should be placed where they are
	  used
	* database does not belong in util, it's AFS specific
        * AFS: cleaner separation between database, encoding, 
	  protocol implementation, shell-tools and GUI code.
	
	And finally, renaming:
	* if we have TCP for peer-to-peer communications,
	  we can't use "TCP" vs. "UDP" to distinguish p2p from
	  client-server, thus: "UDP" becomes "p2p" and "TCP"
	  becomes "CS". At least where they were used to distinguish
	  node-to-node and client-server (gnunetd).

Sun Aug 25 15:02:31 EST 2002
	Releasing GNUnet 0.4.6.

Thu Aug 22 01:31:21 EEST 2002
	gnunet-gtk should now be able to perform multiple 
	search and download operations simultaneously (atleast a couple).

Tue Aug 20 23:11:10 EEST 2002
	Fixed segfault in gnunet-search and gnunet-gtk which appeared
	when there was lots of results.
	Modified gnunetd to return more results at once if there
	is excess bandwidth.
	
Sun Aug 18 23:57:10 EST 2002
	Reworked the lookup-database. The old database got
	into trouble storing data when it was 6% full. Some
	simulations show that the new approach should manage
	94% and should be about as fast (more CPU, presumably
	slightly fewer random disc accesses).
	This change is INCOMPATIBLE with 0.4.5. You *must*
	run "gnunet-check -a" before starting this new version
	of gnunetd in order to migrate to the new format. For
	database simulation and statistical numbers, see
	also src/historical/simula.c.

Fri Aug 16 17:07:15 EST 2002
	Releasing GNUnet 0.4.5.

Fri Aug 16 16:43:39 EST 2002
	Added feature that will allow the specification of
	multiple URLs for downloading the initial hostlist.

Mon Aug 12 02:28:14 EST 2002
	Fixed big problem in requestmanager that would
	make downloads *very* slow for no good reason
	at all (ttl increment in wrong place would make
	us defer the next request for more than twice
	as long as needed, plus some other minor bugs).

Mon Aug 12 01:31:03 EST 2002
	Fixed bug #347 (option "-H" to gnunet-clients for 
	connecting to a remote gnunetd node).

Mon Aug 12 01:10:17 EST 2002
	Fixed bug #348 (no more scan of the entire database
	on startup, instead the databases (gdbm, tdb) contain
	an entry that gives the nubmer of entries). Note that
	this is not done for contentdatabase_directory.

Sun Aug 11 17:00:03 EEST 2002
	Crude file insertion capabilities added to gnunet-gtk gui.

Thu Aug  8 19:13:34 EST 2002
	Added progress bar / printing of insertion status to
	gnunet-insert (option "-V").

Thu Aug  8 19:02:33 EST 2002
	Cleaning up code (establishing sessions, etc.)

Thu Aug  8 18:03:05 EST 2002
	Fixed bug #343 (overflow in stats) by moving to
	long long. Let's hope that __BYTE_ORDER is
	actually defined outside of netinet/in.h.

Thu Aug  8 17:47:17 EST 2002
	Fixed gnunetd segfaulting if gnunet.conf is not 
	available. Also, recvfrom returning -1 with
	errno == EAGAIN was fixed earlier.

Wed Jul 31 23:38:36 EST 2002
	Released 0.4.4.

Wed Jul 31 21:35:53 EST 2002
	Fixed bug with TCP connection that would not
	free thread resources and eventually lead to
	gnunetd not being able to start new threads 
	anymore (mantis: #339).

Tue Jul 30 23:38:51 EST 2002
	Fixed SIGHUP exiting. The main loop was exiting
	because recvfrom returned -1 with errno EINTR,
	which caused us to break out of the main loop.
	Also added gnunetd.pid file to simplify killing
	(or re-reading configuration of) the server.
	You must specify the PIDFILE in gnunet.conf!

Tue Jul 30 20:38:47 EST 2002
	Started writing code to enable re-reading of the
	configuration file whenever we receive a SIGHUP.
	Works, except that after we've read the new
	config file, gnunetd exits (unknown why). 

Mon Jul 29 18:52:23 EST 2002
	Added shutdown code that terminates connection when 
	SIGTERM is received (to avoid keeping lots of UDP
	traffic for the next couple of minutes from hosts
	that still believe we're up).
	
Sat Jul 27 12:39:47 EST 2002
	Added code to measure network load asymmetrically (useful
        for DSL users).

Fri Jul 26 22:46:54 EST 2002
	Released 0.4.3.
	
Wed Jul 24 21:13:08 EST 2002
	Fixed bug in locking and segfault (Linux tolerated,
	BSD crashed, both in connection.c), added logging service.

Tue Jul 23 00:41:17 EST 2002
	Made gnunetd fork like a nice deamon should. Also
	started to add a logging service.
	
Sun Jul 21 20:39:20 EST 2002
	Fixed issue with check_database (index checking too
	strict if content is available in database and 
	on-demand encoded; also a bounds check was missing).

Sun Jul 21 16:05:20 EST 2002
	Fixed deadlock in heloexchange (knownhost requires
	recursive lock).

Sun Jul 21 02:02:32 EST 2002
	Improved routing table. Now does more dynamic memory 
        allocation, reducing the fixed-size per slot from 700
	to 56 bytes. Increased number of slots from 512 to
	8092 (which is the optimal number for a 56 kbps 
        modem connection).

Sat Jul 20 23:57:06 EST 2002
	Fixed bug that caused problems for files
        that were indexed and that had spaces in 
        the filename.

Wed Jul 17 22:50:24 EST 2002
	Fixed bug that prohibited a transitive HELO exchange
	in many cases.
	
Wed Jul 17 01:48:44 EST 2002
	Fixed a couple of bugs in gnunet-check and the
	insertion-tools. Now gnunet-check seems to run like
	a charm. Running it to detect and fix problems in
	the GNUnet databases seems now recommendable :-).
	Note that you must stop gnunetd before running 
	gnunet-check.

Mon Jul 15 22:27:45 EST 2002
	Added return values for insertion. If we run out of
	space (in particular for the fixed-size index
	database), we can now communicate the problem to the
	user.
	gnunet-check is now pretty much feature-complete,
	but it takes of course very, very long to run. There
	is now also a man-page for gnunet-check.

Thu Jul 11 11:33:34 EST 2002
	Added randomized order of blocks for the download
	(patch by I. Wronsky).

Thu Jun 20 21:13:21 EST 2002
	Added HANGUP, a message send if one side terminates the connection.
	Sending the message is optional, but it is nicer to have it. Also
	started on gnunet-check, a tool to check database consistency.

Thu Jun 20 03:11:01 EST 2002
	Improved handling of collisions in the hashes in the
	lookup module (uses no longer a linear scan on the
	collisions file but a hashtable for the collisions!).	
	
Tue Jun 18 20:29:38 EST 2002
	Released GNUnet 0.4.2.
	
Tue Jun 18 20:20:55 EST 2002
	Fixed bugs in blacklisting IPs. Added feature to allow specification
	which networks are trusted enough to connect to the trusted TCP
	port (TCP/2086 no longer needs to be firewalled!).
	
Tue Jun 18 02:35:53 EST 2002
	Fixed problems with ttl (negative TTL queries were forwarded),
	also better flushing of buffers and fewer SKEY exchanges due to
	a now working implementation of the blacklist. A DNS lookup for
	the NAT-box-IP configuration was also added.

Sun Jun 16 04:11:01 EST 2002
	Added code to provide statistics (gnunet-stats).
	Incomplete.

Sun Jun  9 22:56:02 EST 2002
	Released GNUnet 0.4.1.
	
Sat Jun  8 05:00:36 EST 2002
	Several small bugfixes (list of shared files not updated on 
        insertion, highest-bit of trust not interpreted as dirty,
        rpm dependency on libextractor added.
        Also many improvments to the build process.

Wed Jun  5 17:01:58 EST 2002
	Made sure that HELOs don't trigger Ping-Pong if we don't
	really learn anything new.

Tue Jun  4 17:17:45 EST 2002
	The port numbers were not in network-byte order. Fixing
	this is trivial, but it breaks compatibility with 0.4.0. 
	Thanks to Rick Kennell for reporting the endianess issue.
	
Mon Jun  3 20:35:47 EST 2002
	Fixed bug with CRC not endian-converted in gnunet-gtk.
	Added mimetype and filename support to gnunet-gtk.

Sun Jun  2 03:52:18 EST 2002
	Released 0.4.0.

Sat Jun  1 22:13:12 EST 2002
	Added three-way handshake for SKEY exchange. Not tested.
	
Sat Jun  1 16:55:18 EST 2002
	Fixed potential DDoS problem where malicious hosts could
	trick GNUnet servers to repeatedly probe a non-partitipating host
	trying to establish a connection. I wonder how many other
	p2p systems are vulnerable. (Fix: after HELO, play PING-PONG).
	The endianess issues should be fixed throughout the system, but
	not tested on a real machine so far. 	

Sat May 25 15:55:11 EST 2002
	Moved to new CVS server. First changes towards 0.4.0:
	* mostly-big-endian
	* insert/index via TCP
	* bugfixes (mostly performance)

Sat May 18 16:00:06 EST 2002
	Added mimetype, filename and version number to RootNodes
	(mostly incompatible change!). Added automatic generic keyword
	and mime-type extraction via libextractor to gnunet-insert.

Tue May 14 23:59:40 EST 2002
	New storage database is starting to look good. We can now store
	the data in a directory (one file per block), a gdbm database,
	and presumably (not tested) in a tdb database. 

Sat May 11 22:10:56 EST 2002
	Completed, deployed and tested the new TCPIO code. This changes
	the gnunetd-client protocol. Essentially, we convert the TCP stream
	into records with a length and type header. This should allow us
	to fix bug #212 and add other features in the future. The current
	change is really only changing the core TCP code and not anything
	around it. We should deploy some demultiplexing code later.

Tue May  7 20:56:40 EST 2002
	Added IP blacklisting (for virtual private networks).	

Sat May  4 14:08:23 EST 2002
	Fixed bug with bad insertion of files smaller than 1k.

Fri May  3 23:25:16 EST 2002
	Added IP change detection (useful for dialup) [bug #272].
	Added code to ensure that a HELO is life instantly
	after receiving it, fixing the 'unknown host,
	refusing SKEY problem' (bug #273). Other minor	
	bugfixes (#274, #283).

Sun Apr 14 22:36:03 EST 2002
	Added option to allow NAT boxes not to exchange
	foreign HELOs and thus expose the private
	network. Fixed bug that all other hosts should
	in fact do this exchange.

Sat Apr 13 11:02:59 EST 2002
	Make sure that files are readable before returning TRUE
	in assertIsFile()

Fri Apr 12 03:01:06 EST 2002
	Added padding messages with random if maximum
	packet size is not reached. All encrypted
	packets now look absolutely uniform in size
	for a non-participating adversary (before,
	a host that had few queries may have sent packets
	that were less than the maximum size).

Thu Apr 11 01:43:28 EST 2002
	Added sequence numbers to protocol to defend
	against replay attacks (bug #185). 

Wed Apr 10 02:07:25 EST 2002
	Bugfix gnunet-insert-mp3 (endless loop). 
	Updated documentation.
	
Mon Apr  8 00:07:15 EST 2002
	Fixed endless-loop bug when activemigration is turned
	on (during startup).
	
Fri Apr  5 02:03:13 EST 2002
	Released 0.3.3.
	
Fri Apr  5 00:33:42 EST 2002
        gnunet-gtk, the gtk+ based GUI is now functional and
	has all the features of gnunet-search and gnunet-download,
	including boolean queries. In fact, it is a bit better than 
	gnunet-download as it shows the progress of the download.
	The manpage for gnunet-gtk was updated. Minor bugfixes.
	
Mon Mar 25 02:59:13 EST 2002
	Changed writeFile to use a fourth parameter which is the
	desired permissions for the file. Files in data/hosts
	are now world-readable.	Created man pages

Mon Mar 18 17:56:52 EST 2002
	Released 0.3.2.

Sun Mar 17 10:47:51 EST 2002
	Got rid of far too frequent key exchange attempts.
	Added expiration for very-long-dead host keys. Stopped
	forwarding of expired HELOs (receiver drops anyway).	

Wed Mar 14 05:46:20 EST 2002
	Fixed some file location inconsistencies. All files are
	now in $HOME/GNUnet. RPM installation points to /var/GNUnet
	and the config file is ~/GNUnet/gnunet.conf
	Finished port to FreeBSD. This included mostly changes
	to src/util/statuscalls.c, but also several changes to 
	the build system. Added a stat() call in the server code
	to make sure the config file exists before sending it to
	the OpenSSL conf code. Added getopt to source to fix
	portability issues. Changed FREEBSD defs to SOMEBSD, also
	changed in configure.in. Compiles and works on at least
	FreeBSD 4.5 and OpenBSD 3.0

Wed Mar  6 23:15:36 EST 2002
	Added code for 'fast scan' of the database for
	content to discard (should be called partial
	scan). This improves the startup-time dramatically.
	Every source file got the GNU header. 
	
Tue Mar  5 22:42:36 EST 2002
	Added option for *not* participating in content
	migration. Added timeout option to gnunet-search.
	gnunetd now periodically (1h) scans for new content,
	no restarting required. 

Mon Mar  4 23:21:51 EST 2002
	Optimized routing and content migration. Distance
	of the hash to the identity of the local host is
	now taken into account for routing. Hosts give
	higher priority to content that is close to their
	identity (priority towards keeping it). If the 
	network grows, this should significantly improve
	the performance. Also, the choice of the hosts
	for routing is now based on proximity (to the
	query), the activity level of the host and its
	credit ranking.

Sun Mar  3 00:14:58 EST 2002
	Implemented binary queries ("AND") for gnunet-search.
	Made sure that content is not downloaded again if
	already present (if there is other content, we
	overwrite). Fixed bug in gnunet-download 
	(uninitialzied time-to-live).
	
Sat Mar  2 01:57:37 EST 2002
	Finished porting the download-code to C. Now files can
	be downloaded in using shell commands. No GUI though.
	Released GNUnet v0.3.1.

Wed Feb 20 23:47:19 EST 2002
	Big CVS moving operation. 

Sat Feb 16 23:17:27 EST 2002
	Started migration to GNUnet. 

Sun Feb  3 01:20:37 EST 2002
	Extracted crc32 method from zlib and put only that method into
	primitives. Reduces our memory footprint (if nobody else uses
	zlib) and we no longer depend no that library (always good).

Sat Feb  2 22:56:32 EST 2002
	Building final tarball for v0.3.0. 

Wed Jan 30 23:41:04 EST 2002
	Created mp32gnet, a tool to automaticall index mp3 files
	using information from the mp3 header as keywords (title,
	artist, album, comments). The mp3 parsing code comes from
	the GPL tool mp3info.

Tue Jan 29 17:36:48 EST 2002
        Fixed bug with files that were not closed under certain
        circumstances and lead to an exhaustion of the number of
        concurrently open files.

Mon Jan 21 23:34:44 EST 2002 
	Bumping version numbers to v0.3.0 (not yet released, needs some
	more testing to be on the safe side).
	
Sun Jan 20 02:09:06 EST 2002
	Content gathering now discards the least important
	content in favour of new, more important content (if
	there is not space for all content). The cron
	management is now used everywhere. The rpm, the init-script
	and the gproxy shell script have been revised.
	
Sun Jan 13 23:17:58 EST 2002
	Created cron management, replacing old control
	thread (allows for better timing of events).
	EvaluateContent now gets the priority of the
	query that the content had.
	
Sun Jan 13 00:54:56 EST 2002 
	Improved choice in number of hosts to forward
	queries to (now dynamic, depending on priority, etc.)
	Removed many, many allocations in print statements
	which also caused memory leaks if active (see 
	debugging.h).
	Added CRC checking of the root node in GProxy. Fixed
	problem with CRC in IBlocks for large files.
	Added dialog to GProxy to choose where to save the file.

Sat Jan  5 14:25:31 EST 2002
	Optimized routing table. Routing table is now a hashtable
	(collisions are handled by droping either the former or the
	new entry). Each bucket has it's own lock, the global
	semaphore is gone. The table has many more entries (we can
	afford that now that there is no longer a linear search).

Wed Dec 26 19:30:41 CET 2001 
	Created v0.2.0

Tue Dec 25 21:24:18 CET 2001 
	Fixed TTL errors that made queries loop. Added host-evaluation
	to policy (drop packets from untrusted hosts under load). Found that CRC-errors
	are related to policy decisions ("drop"), cosmetic fix.

Sun Nov 25 08:10:52 EST 2001
	Added triple-hash functionality and on-demand encoding (lookup.c). 

Sat Nov 24 07:46:10 EST 2001
	Added randomized choice of hosts for the hosttable.

Thu Nov 22 04:57:57 EST 2001
	Fixed another bunch of big bugs, tested, seems to work smoothly. Creating V0.1.0.

Mon Nov 19 01:22:42 EST 2001:
	Fixed biggest (show-stopper) bugs. Creating V0.0.3

Fri Oct 26 02:20:00 EST 2001:
	Created ChangeLog. Report important changes here,
	report small changes to CVS only.
