gnunet/ChangeLog

	Releasing GNUnet 0.9.0pre3.  Instead of listing all that has
	changed, here is the short list of what is known NOT to work,
	in order of minor flaws to major issues, by module:

	* FS still has a few missing features, but largely works
	* DATASTORE is O(n) where it should be O(log n) for some operations
	* TRANSPORT-UDP does not work (only messages < 1500 bytes, no fragmentation)
	* TESTING does not support incremental HELLO changes
	* TRANSPORT ATS is not used for actual bandwidth assignment,
	          important options to make it truly useful are still missing
	* NAT traversal partially works for TCP (ICMP-based method only)
	* MESH does not work (mock API emulates for VPN)
	* VPN is experimental
        * TRANSPORT-WLAN is experimental
	* CHAT is experimental, has known bugs and was not reviewed yet
	* MONKEY is highly experimental
	* FRAGMENTATION library is not implemented

	With this release we will finally start with
	a detailed accounting of changes in the ChangeLog.

Thu Dec 23 23:33:05 CET 2010
	Releasing GNUnet 0.9.0pre2.

Thu Oct	 7 20:51:05 CEST 2010
	Removed dependency on GNU MP (GMP). The code now uses the libgcrypt MPI
	interface.

Sat Jul  3 20:47:45 CEST 2010
	Releasing GNUnet 0.9.0pre1.

Wed Jun 23 16:34:38 CEST 2010
	Added support for systemd-compatible passing of listen-sockets
	by ARM to services as well as systemd compatibility for gnunet-service-arm
	itself.  At least for non-MINGW systems this should work.

Sat Jun  5 18:08:39 CEST 2010
	Added support for UNIX domain sockets, code also defaults to
	them when available.

Sun May  2 13:49:10 CEST 2010
	Fixed problem with platform-dependence of format for IP addresses
	in HELLOs for TCP and UDP transport.
	Reduced address length field in HELLOs to 16 bit (was 32 bit).
	These changes break transport compatibility.

Fri Apr 16 18:19:05 CEST 2010
	Nearly complete rewrite and new overall architecture.  Many
	features are still missing, but basic system seems to be
	working again.  Maybe time to again track major changes
	in the ChangeLog.  Releasing 0.9.0pre0.


Sun Feb  1 19:51:40 MST 2009
	Fixed Mantis #1429 (struct padding could cause sizeof
	to be different on AMD64, using gcc-ism "packed" to
	avoid this problem).

Sun Feb  1 00:37:16 MST 2009
	Fixed problem in DHT client protocol that could cause
	PUT requests from clients to be (frequently) lost.

Sun Nov  2 16:06:47 MST 2008
	Fixed problem with MySQL disconnects in one module
	impacting MySQL correctness in another module (caused
	crashes).

Sat Aug 16 00:18:34 CEST 2008
	Improved keyword extraction
	Fixed expiration time of keywords
	Releasing 0.8.0b.

Sun Jul 20 15:27:11 MDT 2008

Thu Jul 10 00:59:31 MDT 2008
	Fixed bug where datastore resizing would not
	result in bloomfilter update during gnunet-update.

Sat Jun 28 23:43:00 MDT 2008
	Fixed bug preventing namespace advertisements from
	being processed.

Sat Jun 14 00:54:39 MDT 2008

Fri Jun 13 23:51:00 MDT 2008
	GNUnet now compiles on OpenBSD.

Wed Jun 11 22:17:09 MDT 2008
	Made state of gnunet-auto-share persistent.
	Added support for multiple directories.  Improved
	FSUI/ECRS APIs to reduce the number of threads needed
	for probing.  Increased number of concurrent probes
	allowed.

Sat Jun  7 17:54:49 MDT 2008
	Simplified namespaces a lot.  Shorter timeouts for
	trying to connect to gnunetd to prevent interactive
	apps from blocking too long when gnunetd is not
	running.

Sun Jun  1 21:11:54 MDT 2008
	Releasing 0.8.0pre1.

Sun Jun  1 13:41:27 MDT 2008
	Split of libgnunetpseudonym from libgnunetnamespace
	(with major API extension and changes).

Tue May  6 04:10:02 MDT 2008
	Added simple sanity check for [MODULES] values.
	Added "-s" and "-q" options to gnunet-peer-info.

Thu Apr 24 00:05:17 MDT 2008
	Simplified FSUI stop/abort/pause/resume API calls
	(no need to pass FSUI context anymore).

Mon Apr 21 21:05:20 MDT 2008
	Adding buffered IO for FSUI's serialize and
	deserialize code.

Sun Apr 20 20:01:20 MDT 2008
	Fixed bug in HTTP transport causing lonely messages
	(responses to GET) not to be delivered.

Mon Mar 24 21:15:36 MDT 2008
	Fixed various problems with downloading locally
	indexed large files (downloading large files from
	other peers should not have been a problem).

Sun Mar  2 15:33:41 MST 2008
	Added option to allow user to disable IPv6 support.
	Releasing 0.8.0pre0.

Sat Mar  1 21:14:02 MST 2008
	Fixed some dstore performance issues.
	Made transports alternate between trying IPv4 and IPv6
	if both are available (since one of them maybe
	misconfigured).

Mon Feb 25 23:25:48 MST 2008
	Cleanup of the DNS code: removed GNUNET_IPvXAddress
	and GNUNET_PRIP; centralized all DNS lookup code in
	util/network/dns.c; improved IPv6 support for
        network-client code.

Mon Feb 25 00:01:27 MST 2008
	Added asynchronous search and download methods for
	ECRS library.  FSUI now can do with only one thread
	per search or download (until now, we had two
	threads per search / download).

Tue Feb 19 20:35:28 MST 2008
	Updated database schemata to support O(1) operations
	even if there are N files under the same keywords.
	This breaks database backwards compatibility (and
	no migration code is provided).

Mon Feb 18 19:47:37 MST 2008
	Added new options -u and -s to gnunet-insert.

Sat Feb 16 21:37:33 MST 2008
	Implemented gnunet-auto-share for automatic
	sharing of directories.

Thu Feb 14 01:02:32 MST 2008
	Made HTTP transport work over IPv6 as well.

Wed Feb 13 22:59:07 MST 2008
	Modified mySQL and SQLite datastores to return diverse
	result sets during (partial) hash-based get iterations
	(should result in more diverse keyword result sets).

Tue Feb 12 23:54:34 MST 2008
	First shot at integrated hostlist HTTP server based
	on libmicrohttpd.

Sat Feb  9 22:06:23 MST 2008
	Minor changes to the ECRS/FSUI APIs for searches
	(no more timeouts and/or max-results).  Clients who
	need these features could easily implement them
	directly (and they are not really useful to begin
	with).
	Also, the IPv4 and IPv6 protocols are being integrated
	so that we only listen to one port (running both IPv4
	and IPv6 over the same port).  This break transport
	compatibility, but given that we're breaking protocol
	compatibility for file-sharing already, this may
	actually be a bit of a good thing (since it will now
	be possible to tell if peers running the new GAP code
	are connected to other peers running the new GAP code).

Sun Feb  3 13:17:09 MST 2008
	Dramatic changes to the GAP implementation (breaking
	protocol compatibility).  Essentially, we can save
	a few bytes in each reply.  More importantly, the new
	code allows the searching client to specify a set of
	replies that are not desired (hopefully helping to
	dramatically increase the diversity of search replies
	obtained over time).  Note that the actual encoding
	and databases are not affected (just P2P protocol).
	The update is not complete yet, but should compile.

Tue Jan  8 20:07:20 MST 2008
	Added option for testing ("make check") to use weak(er)
	PRNG for key generation (thanks to Werner Koch for
	pointing out how to do it).

Thu Dec 22 20:10:37 MST 2007
	Releasing GNUnet 0.7.3.

Sun Dec  9 14:34:32 MST 2007
	Implemented MySQL version of the dstore-module.  This
	means that sqLite is now again truly optional.

Sat Dec  8 15:15:53 MST 2007
	Integrated F2F topology into main topology module
	(options are used to choose between F2F-only (old F2F),
	 minimum number of friend connections (NEW) or entirely
	 arbitrary connection set (default)).

Thu Dec  6 20:51:17 MST 2007
	The SMTP transport is working again.

Thu Nov 22 20:49:16 MST 2007
	United all libgnunetutil_*.so libraries into one big
	libgnunetutil.so library (eliminates issues for binary
	packagers and reduces file size by about 20%).  Also
	made sure that all exported symbols start with "GNUNET_".

Sat Sep 29 16:48:24 MDT 2007
	Improved MySQL sqstore module performance.
	Releasing GNUnet 0.7.2c.

Sat Sep  8 18:01:36 MDT 2007

	Fixing log rotation.

Sat Jul 21 23:42:11 MDT 2007
	Radical changes to MySQL implementation (trying to
	address certain scalability issues).

Sat Jul  7 00:22:47 MDT 2007
	Releasing GNUnet 0.7.2a.

Fri Jul  6 22:54:52 MDT 2007
	Fixed bugs in F2F topology code.  Eliminated a few
	confusing LOG messages.

Sun Jul  1 20:35:00 MDT 2007
	Fixed issue with too many TCP connections being
	created.  Reduced CPU overheads by increasing
	requirements for grouping of messages.  Improved
	various error messages.

Sat Jun 30 01:55:34 MDT 2007
	Improved bloomfilter recomputation after quota change.
	Fixed bloomfilter size computation.  You must run
	gnunet-update (will take a while).

Fri Jun 29 00:56:03 MDT 2007
	Avoid re-connecting shortly after connection was shutdown.

Thu Jun 28 01:10:01 MDT 2007
	Fixed high-latency problems for certain SQLite operations.
	Also improved SQLite performance (but not scalability) a
	bit.  Resolved MySQL disconnect crash (gnunetd would crash
	if mysqld was stopped).

Sat Jun 23 16:56:03 MDT 2007
	Improved CPU consumption from content migration code
	by querying the DB less often, using the same content
	for more peers (at the expense of 1 MB extra memory
	utilization).  Fixed a deadlock.

Wed Jun 20 17:10:38 MDT 2007
	Fixed bug in MySQL module.

Sun Jun 17 00:09:13 MDT 2007
	Releasing GNUnet 0.7.2.

Sat Jun 16 04:43:20 MDT 2007
	http transport is amost back, now needing the
	new libmicrohttpd.  However, the code is still
	highly experimental and not ready for production
	use.

Fri Jun  8 23:44:01 MDT 2007
	Fixed bugs preventing namespace search from
	working.  Also extended testcase to cover
	namespace search.

Tue May 29 23:15:27 MDT 2007
	Fixed a major bug which resulted in peers without
	traffic between them disconnecting (even if that
	session was their only connection).
	Fixed another major bug where nodes would not
	properly forward HELLOs from other peers (given
	certain common/default configuration options).

Sun May 27 22:39:48 MDT 2007
	Added new API gnunet_testing_lib.h to make it
	easier to write testcases that need to start
	gnunetd.  API is now used everywhere and the
	ugly peer.conf files and directories are gone.
	Fixed a bug with inserting empty directories.
	Extended ECRS API to allow partial file download.

Sat May 26 18:24:15 MDT 2007
	Fixed bugs with testcases (changes in names and
	structure of options were not reflected in .conf
	files for various testcases).
	Fixed issues with command-line option handling (failed to
	override configuration file options).

	Fixed problem with split-extractor keywords not being used
	for uploads.

Tue Jan 16 21:43:26 MST 2007
	Expanded transport APIs to avoid building messages for
	transmission just to have them rejected by blocking TCPs
	with full transmission queues (happened quite a bit).

Mon Jan  8 22:21:15 MST 2007
	Making computation of send buffer permuations more
	efficient (in terms of calling weak_randomi) by only
	computing permuations over the actually selected messages.

Mon Jan  8 21:34:02 MST 2007
	Forcing -O3 for crypto library (performance critical).
	Enforcing message queue limit for daemon (somehow got lost

Sat May  6 00:17:59 PDT 2006
	Releasing GNUnet 0.7.0d.

Fri May  5 01:33:42 PDT 2006
	Fixed bug with priorities of IBlocks of uploaded content
	(priority was left at zero, making those blocks be
	possibly discarded rather quickly once the datastore filled
	up).

Tue May  2 00:01:25 PDT 2006
	Fixed bug in gap where the tracking of query origins for
	optimizing routing paths lacked a simple assignment of the
	query origin (found by code inspection).  As a result,
	routing performance should improve further.  Also fixed
	small memory leak in gap and reduced memory consumption by
	fixing Mantis #1058.

Sat Apr 22 13:50:39 PDT 2006
	Fixed bug in util/cron.c where stopCron() would wait for an

	Releasing GNUnet 0.7.0c.

Thu Mar 16 22:14:01 PST 2006
	Fixing various routing problems (resulting in better utilization

	Added Swedish translation.

Sun Jan  1 21:35:59 PST 2006
	Reduced amount of hashing done to be O(n) and not O(n^2) for
	n local search results (for example, for 100 results, this can

Sat Dec 31 17:02:37 PST 2005
	Added support for using -k multiple times in gnunet-pseudonym.

Wen Dec 28 00:22:54 CET 2005

	(faster, avoids pollution of the routing table when not needed).

Sun Aug 21 18:42:14 PDT 2005
	Fixed memory leak in gnunet-insert -R.  Improved memory utilization
	by SQlite dramatically (see discussion on gnunet-developers).

Sat Aug 20 21:04:28 PDT 2005
	Fixed (rare) segmentation fault in insertion code.

Sat Aug 20 19:31:10 PDT 2005
	Yet another tiny bug -- but one that hangs gnunetd; fixed in pre6a.

Sat Aug 20 13:51:01 PDT 2005
	Releasing 0.7.0pre6.

Sat Aug 20 12:51:27 PDT 2005
	Changed sqlite data format to avoid encoding-decoding
	(breaks compatibility with previous datastores, in particular
	 since conversion code is NOT provided).
	 The page size was also increased, rendering the database files

	without gettext/NLS support and for 64-bit size_ts.
	Also fixed a couple of other compiler warnings.
	Cleaned up connection.c code.

Mon Jul 11 14:41:18 CEST 2005
	Fixed tiny memory leak in http_bootstrap.

Mon Jul 11 02:22:24 CEST 2005
	Fixed long-standing problems in statuscalls wrt
	network load estimates, leading to too-high bandwidth
	consumption on average.  Fixed minor memory leaks.
	Fixed far too often session-key exchange (was done
	also for sessions that were already up).

Thu Jul  7 15:22:21 CEST 2005
	Fixed bug in identity, missing ntohs for protocol ID.
	Fixed bug in topology, wrong calculation of saturation.

Wed Jul  6 22:34:30 CEST 2005
	Fixed bugs in core with respect to possible infinite
	recursion caused by fragmentation callbacks.  Also
	differenciated between fatal transport sends and
	transient transport sends.  Cleanup of some APIs.

Sat Jul  2 17:21:07 CEST 2005
	Fixed bugs in gnunet-pseudonym (listing of namespaces),
	FSUI (double-free for namespace creation), cleaned up
	APIs and implemented clearing of completed downloads
	(FSUI). Releasing 0.7.0pre4.

Fri Jul  1 15:08:42 CEST 2005
        Added statistics for transports and other connection-
	related functions.  Prevented core from dropping
	messages just because transport is (temporarily)
	blocked.  Made transport selection in identity random
	again where necessary.

Thu Jun 30 20:05:15 CEST 2005
	Added cache for KBlocks (can speed up insertion speed
	for recursive inserts quite a bit).

Thu Jun 30 13:52:17 CEST 2005
	Enabled IPv6 by default.  Fixed various minor bugs.

Tue Jun 28 13:41:58 UTC 2005
	Fixed various open FIXMEs, including error handling,
	bad performance and some memory leaks (gnunet-tools
	only, not in gnunetd).

Mon Jun 27 17:21:09 CEST 2005
	Fixed double-free segfault.
	Fixed problem with session timeout not happening.
	Fixed issue with too lazy slot reclaim for reconnect.
	Made reconnect scanning more incremental (1/10th of
	the work every 500ms instead of full work every 5s).
	Fixed memory leak in advertisement processing.

Sun Jun 26 18:21:17 CEST 2005
	Plenty of bugfixes everywhere, gnunet-setup works
	now.  Releasing 0.7.0pre3.

Sat Jun 11 11:25:24 EST 2005
	Fixed various problems with recursive upload
	(thread stack size too small, wrong filenames
	passed around, wrong list of filenames updated).

Sat Apr  2 01:54:23 EST 2005
	Various bugfixes, some of them critical (segfaults,
	protocol errors (resulting in failures to connect),
	old version of configuration file would be
	generated if configuration was missing,
	gnunet-insert would not properly work with multiple
	keywords (-k and -K options)). Releasing 0.7.0pre2.

Thu Mar 31 21:38:06 EST 2005
	Releasing 0.7.0pre1.

Tue Mar  8 14:45:55 EST 2005
	OpenSSL cannot fully support SHA-512.  Eliminated as an
	option (not necessary, GPL incompatible, trouble, work
	to maintain -- in summary: not worth it).

Sat Mar  5 00:33:51 EST 2005
	Changing hash algorithm to SHA-512.
	Changing symcipher algorithm to AES-256.

Sun Feb 27 21:59:31 EST 2005
	All unit testcases pass.  Releasing 0.7.0pre0.

Sat Feb 12 17:35:08 EST 2005
	Fixed mysql-test.  Changed MySQL to use prepared statements,
	avoids conversion (mysql_escape_string) and is faster on the
	server-side, too.

Wed Dec 15 20:47:40 EST 2004
	Removed support for password encryption of namespace keys.
	Hardly used and adds hardly any security.  Encrypt /home if
	you need this, would be more effective anyway.

Fri Nov 26 06:27:12 EST 2004
	Sessionkey exchange works now, at least with OpenSSL.  There
	seems to be some quirk in some version of libcrypt with
	respect to RSA encryption.  Anyway, it is a heisenbug (sometimes
	RSA decryption does not result in what was originally
	encrypted), but I have the feeling this problem existed
	already in 0.6.5 -- and it is now detected and does not
	occur all the time.

Tue Nov 23 02:35:50 EST 2004
	The CVS may look like it's compiling, but that's just because
	most of the service modules are not even attempted.
	And without those, nothing will work.  But in good news,
	util, transport and server do compile now.

Sun Nov 21 03:53:22 EST 2004
	Starting to make incompatible changes.  Once this is commited
	to CVS (which will only happen once at least some parts compile
	again), this version will no longer be compatible with any
	previously released version of GNUnet (and highly experimental).
	Do not yet use the new code on-line, do not expect it to work
	at all!

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.

Sat Sep 25 22:29:48 EST 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).

	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).

Wed May  5 17:34:39 EST 2004
	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).

	download.

Sat Apr 10 21:17:46 EST 2004

	gnome-system-monitor code.

Fri Apr  9 22:01:51 EST 2004
	Added support for libextractor > 0.2.7.

Fri Apr  9  0:29:20 EST 2004
	Completed --help conversion.

Wed Mar 31 15:40:51 EST 2004
	Releasing 0.6.1d.

Tue Mar 30 22:42:13 EST 2004
	Integrated gnunet-pseudonym-create, -delete and -list into
	gnunet-pseudonym as well as gnunet-directory-list, -emptydb
	and -print into gnunet-directory.

Tue Mar  2 10:46:01 EST 2004
	Fixing bug preventing download for indexed files <= 1k.

	Releasing 0.6.1b.

Fri Jan 23 00:00:09 EST 2004
	Fixed indexed content being overwritten by migrated content

Thu Jan 22 19:27:33 EST 2004
	Fixed integer-overflow problems in statuscalls.
	Fixed missing ttl/priority adjustment for NS-Queries.
	Fixed bug in routing that would let very old queries survive.

Thu Jan 15 23:14:54 EST 2004
	Fixed size of super-bloomfilter (was factor of 32 to small).
	Fixed option -r of gnunet-check (would not increment bloom filters
	to appropriate value).

Wed Dec 31 17:07:40 EST 2003
	Fixed various routing and bandwidth allocation problems.
	Releasing 0.6.1a.

Wed Dec 24 00:00:00 EST 2003
	Releasing 0.6.1.

Fri Dec 19 00:57:29 EST 2003
	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)

Wed Sep 17 22:59:16 EST 2003
	Fixed problems with updates in namespaces in the GTK code.
	Added boolean search capability (x AND y) to GTK search.
	Made namespace search frequency respect TTL delays.

Sat Jun 14 19:21:41 EST 2003
	Added support for HTTP-PROXY to download the hostlist.

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
	Added BSD DB (libdb) support.

Sun Mar 23 04:04:38 EST 2003
	Big gnunet-gtk cleanup.

Tue Mar 18 01:52:18 EST 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.
