151 cross-platform compatibility.
152 * ping plugin: Correct the handling of the `TTL' setting.
153 * swap plugin: Reapply a patch for Solaris.
154 * tcpconns plugin: Portability improvements.
156 2008-02-18, Version 4.3.0
157 * collectd: Notifications have been added to the daemon. Notifications
158 are status messages that may be associated with a data instance.
159 * collectd: Threshold checking has been added to the daemon. This
160 means that you can configure threshold values for each data
161 instance. If this threshold is exceeded a notification will be
163 * collectd: The new `FQDNLookup' option tells the daemon to use the
164 full qualified domain name as the hostname, not just the host part
165 es returned by `gethostname(2)'.
166 * collectd: Support for more than one `TypesDB' file has been added.
167 This is useful when one such file is included in a package but one
168 wants to add custom type definitions.
169 * collectd: The `Include' config option has been expanded to handle
170 entire directories and shell wildcards.
171 * collectdmon: The new `collectdmon' binary detects when collectd

181 domain name lookups in this plugin.
182 * perl plugin: Many internal changes added support for handling multiple
183 threads making the plugin reasonably usable inside collectd. The API has
184 been extended to support notifications and export global variables to
185 Perl plugins; callbacks now have to be identified by name rather than a
186 pointer to a subroutine. The plugin is no longer experimental.
187 * uuid plugin: The new UUID plugin sets the hostname to an unique
188 identifier for this host. This is meant for setups where each client
189 may migrate to another physical host, possibly going through one or
190 more name changes in the process. Thanks to Richard Jones from
191 Red Hat's Emerging Technology group for this plugin.
192 * libvirt: The new libvirt plugin uses the `libvirt' library to query
193 CPU, disk and network statistics about guest systems on the same
194 physical server. Thanks to Richard Jones from Red Hat's Emerging
195 Technology group for this plugin.
197 2008-04-22, Version 4.2.7

219 * apache plugin: Improved initialization and error messages.
220 * exec plugin: Set supplementary group IDs.
222 + Create separate threads for reading from the socket and parsing
223 and dispatching incoming packets. Versions prior to this may have
224 problems in high-load situations, where the socket receive buffers
225 overflows, resulting in gaps in the data.
226 + Use `memcpy' when constructing/parsing a package to avoid
227 alignment problems on weird architectures, such as Sparc.
228 + Translate doubles to/from the x86 byte representation to ensure
229 cross-platform compatibility.
230 * ping plugin: Correct the handling of the `TTL' setting.
231 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.

235 2008-01-21, Version 4.2.4
236 * unixsock plugin: A bug in the unixsock plugin caused it not to set
237 the permission on the socket as documented in the manpage. Thanks to
238 Evgeny Chukreev for fixing this issue.
239 * collectd: The documentation has been improved.
241 2007-12-28, Version 4.2.3
242 * sensors plugin: Updated the plugin to build and work with version 3
243 of the libsensors library.
245 2007-12-15, Version 4.2.2
246 * nginx plugin: Incorrect comparison of strings lead to a segfault
247 when using the plugin. Thanks to Saulius Grigaliunas for fixing
249 * logfile plugin: The config option `Timestamp' was handled
250 incorrectly and basically always active. Thanks to Luke Heberling
253 2007-11-08, Version 4.2.1
254 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
256 * snmp plugin: Fix a memory leak.
258 2007-10-27, Version 4.2.0
259 * collectd: The new config option `Include' lets you include other
260 configfiles and thus split up your config into smaller parts. This
261 may be especially interesting for the snmp plugin to keep the data
262 definitions separate from the host definitions.
263 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
264 (number of connections, octets and packets for each service and
265 destination). Thanks to Sebastian Harl for this plugin.
266 * memcached plugin: The new `memcached' plugin connects to a memcached
267 daemon process and collects statistics of this distributed caching
268 system. Thanks to Antony Dovgal for contributing this plugin.
269 * nginx plugin: The new `nginx' plugin reads the status page of an
270 nginx daemon and saves the handled connections and requests.
271 * perl plugin: Many changes, including the added `EnableDebugger'
272 config option which lets you debug your Perl plugins more easily.
273 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
274 be more thread-safe otherwise by locking calls to the library.
275 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
276 correct the values returned by SNMP-agents. If a <data> block is
277 defined as `table' the instance is now optional. The sequence number
278 is used as the type-instance in this case. The new `InstancePrefix'
279 option allows to add arbitrary prefixes to the type-instance.
280 * tcpconns plugin: The new `tcpconns' plugin collects the number of
281 certain TCP connections and what state they're in. This can be used
282 to see how many connections your FTP server has to handle or how
283 many outgoing connections your mailserver has open.
285 2008-01-11, Version 4.1.6
286 * unixsock plugin: A bug in the unixsock plugin caused it not to set
287 the permission on the socket as documented in the manpage. Thanks to

301 `--with-libnetsnmp' has been fixed.
302 * collectd: Implement `strerror_r' if the libc doesn't provide it.
303 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
304 a deadlock or delay when shutting down the daemon.
305 * snmp plugin: Fix a memory leak.
307 2007-10-24, Version 4.1.3
308 * collectd: A build issue under Solaris has been resolved by renaming
310 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
311 be more thread-safe otherwise by locking calls to the library.
313 2007-09-28, Version 4.1.2
314 * apcups plugin: Fix reporting of the `load percent' data.
315 * wireless plugin: Correct the handling of cards returning signal and
316 noise quality as percentage.

326 * collectd: The documentation has been fixed in numerous places.
327 * exec plugin: Setting the group under which to run a program has been
329 * collectd: The `sstrerror' function was improved to work correctly
330 with the broken GNU version of `strerror_r'.
331 * collectd: Write an error message to STDERR when loading of a plugin
333 * apcups plugin: Fix the `types' used to submit the values: They still
334 has an `apcups_' prefix which doesn't work anymore.
335 * rrdtool plugin: Create new RRD-files with the `begin' time set to
336 whatever the client thinks is `now'..
338 2007-09-01, Version 4.1.0
339 * Build system: The build system has been changed to automatically
340 disable all plugins, which are missing dependencies. The dependency
341 checking has been removed from the plugins themselves to remove
343 * Flexible interval: The interval of collected data is now sent along
344 with the data itself over the network, so that the interval-settings
345 of server and clients no longer needs to match.
346 * netlink plugin: The new `netlink' plugin connects to the Linux
347 kernel using a netlink socket and uses it to query information about
348 interfaces, qdiscs and classes.
349 * rrdtool plugin: The cache is now dumped to disk in an extra thread
350 to not block data collection.
351 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
352 network devices, such as switches, routers, thermometers, rack
353 monitoring servers, etc. The collectd-snmp(5) manpage documents this
355 * unixsock plugin: Added the `LISTVAL' command.
356 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
357 of music played with xmms.
359 2007-09-28, Version 4.0.9

367 with the broken GNU version of `strerror_r'.
368 * collectd: Write an error message to STDERR when loading of a plugin
370 * apcups plugin: Fix the `types' used to submit the values: They still
371 has an `apcups_' prefix which doesn't work anymore.
372 * rrdtool plugin: Create new RRD-files with the `begin' time set to
373 whatever the client thinks is `now'..
375 2007-08-26, Version 4.0.7
376 * documentation: Some typos have been fixed and some information has
378 * build system: Many fixes for detecting libraries in unusual places,
379 such as on RedHat systems. The affected libraries are `libcurl',
380 `libmysql', and `libupsclient'.
381 * network plugin: Allow the `Port' option to be specified as a number
382 (i. e. without quotes).

385 * processes plugin: Fix a potential segmentation fault.
387 2007-07-30, Version 4.0.6
388 * sensors plugin: Fix the ignorelist functionality: Only the `type
389 instance' was used to match against the list, but the documentation
390 told otherwise. This release fixes the code, so it complies with the
392 * syslog plugin: Call `openlog' right when the plugin is loaded, so
393 configuration messages will end up in the logging facility.
394 * conrtib/fedora: The contributed specfile for Fedora has been
397 2007-07-05, Version 4.0.5
398 * Portability: More fixes for OpenBSD have been included.

417 they're given in numerically form.
419 2007-06-07, Version 4.0.1
420 * iptables plugin: A bug in the configuration routine has been fixed.
421 Setting a comment in the configfile will no longer cause a
424 2007-06-03, Version 4.0.0
425 * collectd: The plugin-infrastructure has been changed to allow for
426 more types of plugins, namely `write' and `log' plugins.
427 * collectd: The read-function has been changed to read many plugins in
428 parallel, using threads. Thus, plugins generally need to use
429 thread-safe functions from now on.
430 * collectd: The '-t' command line options allows to perform syntax tests
431 of the configuration file and exit immediately.
432 * csv plugin: The new `csv' plugin handles output to `comma separated
434 * rrdtool plugin: The new `rrdtool' plugin handles output to
435 RRD-files. Data can be cached to combine multiple updates into one
436 write to increase IO-performance.
437 * network plugin: The new `network' plugin handles IO via the network.
438 It implements a different, much more extensible protocol which can
439 combine many values in one packet, decreasing the number of UDP-
440 packets being sent. It can read from and send to the network and
441 with the appropriate configuration even forward packets to other
443 * unixsock plugin: The new `unixsock' plugin provides an interface to
444 communicate with the daemon while it is running. Right now the
445 commands `GETVAL' and `PUTVAL' are implemented, but more are to
447 * perl plugin: The new `perl' plugin allows you to write extensions
448 for collectd in the scripting-language Perl.
449 * logfile plugin: The new `logfile' plugin writes logmessages to files
451 * syslog plugin: The new `syslog' plugin sends logmessages to the
452 system's syslog daemon.
453 * entropy plugin: The new `entropy' plugin collects the amount of
454 entropy currently being available to the system.
455 * exec plugin: The new `exec' plugin forks child processes and reads
456 back values provided by the forked processes.
457 * iptables plugin: The new `iptables' plugin reads counters from
458 iptables rules. Thanks to Sjoerd van der Berg for contributing this
460 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
461 to Peter Holik for contributing this plugin.

465 connections) field was added by Florent Monbillard.
466 * collectd-nagios: The new `collectd-nagios' binary queries values
467 from collectd, parses them and exits according to Nagios-standards.
468 * manpages: The manpages have been improved a lot.
470 2007-09-28, Version 3.11.7

481 were accounted as `zombies'.
483 2007-04-10, Version 3.11.4
484 * dns plugin: Change the order of includes to make the plugin compile
487 2007-03-30, Version 3.11.3
488 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
489 of the unused `COLLECT_KSTAT'.
491 2007-02-11, Version 3.11.2
492 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
493 NULL-pointer may have been passed to `printf' which causes a
494 segfault with some libcs.
496 2007-02-10, Version 3.11.1
497 * df plugin: Some wrong defines have been fixed so the plugin works
499 * dns plugin: The usage of a struct has been fixed to work with
501 * processes plugin: Some missing defines have been added so the plugin
502 compiles cleanly under FreeBSD and presumably other UNIXes.
504 2006-12-22, Version 3.11.0
505 * collectd: The new command line option `-P' makes it easier for
506 distributors to change the location of PID-files.
507 * collectd: The daemon shuts down faster now which makes it easier to
508 write init.d-scripts for it.
509 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
510 caused problems every now and then.
511 * df plugin: New config options allow to ignore certain mountpoints,
512 filesystem types or devices.
513 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
514 and interprets it. It collects traffic as well as qtype, opcode and
516 * email plugin: Sebastian Harl has contributed this plugin which
517 counts received mails in categories (e. g. ham, spam, virus), spam
518 score (as given by SpamAssassin) and check types.
519 * mbmon plugin: Flavio Stanchina has contributed this plugin which
520 uses `mbmon' to gather information from sensors on the motherboard.
521 * processes plugin: Collect detailed statistics for configured
522 processes, that's process and thread count, CPU usage, resident
523 segment size and pagefaults.
524 * multimeter plugin: Peter Holik contributed a new plugin which
526 * sensors plugin: Lubos Stanek has put much effort into improving this
527 plugin, including `extended naming', collection of voltage values
528 and the possibility to ignore certain values.
530 2006-12-21, Version 3.10.4
531 * Max Kellermann has identified a bug in the server routine: When
532 opening a socket fails the daemon will (re)try opening the socket in
533 an endless loop, ultimately leading to a `EMFILE' error.
535 2006-11-04, Version 3.10.3
536 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
537 ntpd's reply was sent in more than one packet, the buffer size was
538 calculated incorrectly, resulting in the reading of uninitialized or
541 2006-11-01, Version 3.10.2
542 * The sample config file has been improved.
543 * Errors in the manpages have been corrected.
544 * The ping-plugin now adds hosts during initialization, not during
545 startup. This speeds up startup when no network connectivity is
546 available. Also, the hosts are being added later when the network is
548 * Improved BSD-support for the df-plugin.
549 * Fixed syntax errors in the swap-plugin for Mac OS X.
550 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
552 * Don't disable the mysql-plugin if connecting to the database fails
553 during initialization. Instead, try again in increasing intervals.
555 2006-07-19, Version 3.10.1
556 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
557 the apcups cannot be reached, unconnected sockets will pile up and
558 eventually lead to `Too many open files' errors.
560 2006-07-09, Version 3.10.0
561 * The `disk' plugin has been ported to Darwin.
562 * The `battery' plugin should work on many Apple computers now.
563 * The `traffic' plugin can now ignore certain interfaces. Also,
564 statistics for sent/received packets and errors have been added.
565 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
566 to Anthony Gialluca for contributing this plugin and providing me
567 with a test environment :)
568 * A plugin for monitoring an NTP instance and the local clock drift
571 2006-06-25, Version 3.9.4
572 * The Solaris code in the `swap' plugin has been changed to reflect
573 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
575 * The debugging system has been fixed to work with the Sun libc.
576 * When built without librrd the variable `operating_mode' could be
577 uninitialized. Thanks to David Elliot for reporting the bug.
579 2006-06-01, Version 3.9.3
580 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
581 operating systems also profit from the changes, but I wasn't able to
583 * Changed the build system to find the netinet-includes under FreeBSD
584 and therefore successfully build the `liboping' library there.
586 2006-05-09, Version 3.9.2
587 * Applied a patch to the `liboping' library. Due to a bug in the
588 sequence checking the `ping' plugin stopped working after
589 approximately 7.6 days.
591 2006-05-09, Version 3.8.5
592 * Applied a patch to the `liboping' library. Due to a bug in the
593 sequence checking the `ping' plugin stopped working after
594 approximately 7.6 days.
596 2006-04-21, Version 3.9.1
597 * Build issues with Solaris and possible other architectures have been
599 * Problems when building the `apache'-plugin without `libcurl' have
601 * A bug in the `ping' plugin has been fixed. Sorry folks.
603 2006-04-02, Version 3.9.0
604 * A plugin to monitor the Apache webserver has been added.
605 <http://httpd.apache.org/>
606 * A plugin to collect statistics about virtual servers using VServer.
607 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
609 * A plugin for wireless LAN cards has been added. It monitors signal
610 strength, link quality and noise ratio..
611 * A plugin for Apple hardware sensors has been added.
612 * An option to compile collectd with different `step' and `heartbeat'
613 settings has been added. The size of RRAs is no longer static but
614 calculated based on the settings for `step' and `width'.
615 * The `ping' plugin can now be configured to use a certain TTL.
616 * A plugin to monitor the hardware sensors of Apple computers has been
618 * The plugins `cpu', `memory', `processes' and `traffic' have been
619 ported to Mach/Darwin (Mac OS X).
620 * The `log mode' has been contributed by Christophe Kalt. It writes
621 the data into text files rather than RRD files.
623 2006-04-09, Version 3.8.4
624 * Applied patch by Vincent Stehlé which improves the disk-name
625 resolution in the `hddtemp' plugin for Linux systems.
627 2006-04-02, Version 3.8.3
628 * Applied a patch by James Byers: The MySQL plugin was not working
629 with MySQL 5.0.2 or later.
631 2006-03-14, Version 3.8.2
632 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
633 the GNU libc, because it points to `/etc/fstab' rather than
636 2006-03-13, Version 3.8.1
637 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
638 * Fixes in the debian `postinst' and `init.d' scripts.
640 2006-03-09, Version 3.8.0
641 * The `ping' plugin no longer uses `libping' but a self written
642 library named `liboping'. With this library it's possible to ping
643 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
645 2006-02-18, Version 3.7.2
646 * A simple bug in the `battery' plugin has been fixed. It should now
647 work with ACPI based batteries as well. Thanks to Sebastian for
649 * Fixing a bug that prevented collectd to be built without librrd.
650 Thanks to Werner Heuser for reporting it.
652 2006-02-04, Version 3.7.1
653 * The new network code has been improved to build with older versions
655 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
656 to Tommie Gannert for this patch.
658 2006-01-30, Version 3.7.0
659 * The `battery' plugin has been added. It collects information about
661 * The MySQL plugin has been improved: It now writes two more RRD
662 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
663 * The `cpufreq' plugin now reads another file since the file it did
664 read so far causes much overhead in the kernel. Also, you need root
665 to read the old file, but not to read the new one.
666 * The `hddtemp' plugin can now be configured to connect to another
667 address and/or port than localhost.
668 * The `df' plugin now prefers `statvfs' over `statfs'.
669 * The network code has been rewritten. collectd now supports unicast
670 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
671 be set in the configfile.
673 2006-01-24, Version 3.6.2
674 * Due to a bug in the configfile handling collectd wouldn't start in
675 client mode. This released fixes this.
677 2006-01-20, Version 3.6.1
678 * Due to a bug in `configure.in' all modules and the binary were
679 linked against `libmysqlclient'. This issue is solved by this
682 2006-01-17, Version 3.6.0
683 * A config file has been added. This allows for loading only specific
685 * A `df' plugin has been added.
686 * A `mysql' plugin has been added.
687 * The `ping' plugin doesn't entirely give up hope when a socket error
688 occurred, but will back of and increase the intervals between tries.
690 2006-01-21, Version 3.5.2
691 * Fixed yet another bug in the signal handling.. Stupid typo..
692 * Improved the ping plugin to not give up on socket errors (backport
695 2005-12-18, Version 3.5.1
696 * The PID-file is now deleted correctly when shutting down the daemon.
697 * SIGINT and SIGTERM are now handled correctly.
699 2005-12-16, Version 3.5.0 (Revision 326)
700 * A bug in the `load' module under Solaris has been fixed.
701 * The `users' module has been contributed by Sebastian Harl. It counts
702 currently logged in users.
703 * The CPU module now works under FreeBSD without the use of
704 `libstatgrab', however SMP support is missing.
705 * The default directories for the RRD files and the PID file now
706 depend on the compile time setting of `localstatedir'.
708 2005-11-15, Version 3.4.0 (Revision 236)
709 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
710 from gentoo's bugzilla for writing the patch.
711 * The build dependency for librrd has been removed. Binaries built
712 without librrd are client-only and will multicast their value as
713 with the `-c' argument.
714 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
715 * The newly introduced `-f' switch prevents daemon initialization
716 (forking, closing standard filehandles, etc.) Thanks to Alvaro
717 Barcellos for this patch.
719 2005-11-04, Version 3.3.0 (Revision 216)
720 * New modules have been added:
721 - `serial', for monitoring traffic on the serial interfaces
722 - `nfs', for graphing NFS procedure calls
723 - `tape', traffic from/to tape devices
724 * The memory.rrd now accepts more than 4Gig of memory.
726 2005-10-26, Version 3.2.0 (Revision 200)
727 * Support for graphing the processes has been added (thanks to Lyonel
729 * If reading from hddtemp fails collectd will increase the time
730 between polls up to one day.
731 * The init.d files have been improved.
732 * Problems with the spec file have been fixed.
734 2005-10-16, Version 3.1.0 (Revision 194)
735 * Added the `setsid' syscall to the startup code.
736 * Support for hddtemp has been added (thanks to Vincent Stehlé)
738 2005-09-30, Version 3.0.0 (Revision 184)
739 * The ability to send/receive data to/from the network (think
740 multicast) has been added.
741 * Modules have been split up into shared libraries can be loaded at
742 runtime. The biggest advantage is that the core program doesn't need
743 to be linked against an external library.
744 * A patch by George Kargiotakis has been applied: It fixes the sensors
745 behaviour then more than one sensor is being queried.
747 2005-09-16, Version 2.1.0 (Revision 172)
748 * A module for swap statistics has been added.
750 2005-09-09, Version 2.0.0 (Revision 135)
751 * Filenames can no longer be configured at program startup. The only
752 options as of this version are the directory and ping hosts.
753 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
754 Soft-IRQ statistics are added to `System'.
755 * Diskstats now collect read and write bytes, not sectors.
756 * Ping statistics can now be collected for more than one host. There
757 is no default any more: If no host is given no host will be pinged.
758 * A self-written patch for libping has been applied so it builds
761 2005-09-01, Version 1.8.1 (Revision 123)
762 * Much improved configure-script: libraries and features may now be
764 * More detailed warnings/error messages when RRD update fails.
766 2005-08-29, Version 1.8.0:
767 * Support for collecting disk statistics under Solaris.
769 2005-08-25, Version 1.7.0:
770 * Support for libstatgrab[1] for load, memory usage and network
771 traffic. CPU- and disk-usage are not (yet) supported, since
772 libstatgrab returns insufficient information. I will contact the
774 * Improved the CPU-initialization code for Solaris. Apparently CPUs
775 aren't necessarily counted linear which is now handled correctly.
776 [1]: http://www.i-scream.org/libstatgrab/
778 2005-08-21, Version 1.6.0:
779 * Basic support for Solaris: System load and cpu-usage can be
780 collected under Solaris, too. Other stats will follow later.
781 * Many fixes in the autoconf-script
782 * Collection/Museum scripts have been added under contrib/museum
783 * collectd may now be started in unprivileged mode, though ping
784 statistics will not work.
786 2005-07-17, Version 1.5.1:
787 * Diskstats-RRDs now use major/minor for naming. Some systems have
788 weird strings as disk-names..
790 2005-07-17, Version 1.5:
791 * A new module, diskstats, has been added. It collects information
792 about the disks and partitions.
794 2005-07-11, Version 1.4.2:
795 * The meminfo module has been changed to work with more platforms
796 and/or kernel versions.
798 2005-07-10, Version 1.4.1: Correct traffic stats
799 * The traffic rrd-file is now created with DS-type `COUNTER' which I
800 forgot to correct when I changed that module.
802 2005-07-09, Version 1.4: More traffic stats
803 * Traffic is now collected for all interfaces that can be found
804 * Temperature-statistics are read from lm-sensors if available
806 2005-07-08, Version 1.3: CPU stats
807 * Collecting CPU statistics now
809 2004-07-12, Version 1.2: Using syslog
810 * collectd is now using the syslog facility to report errors, warnings
812 * The default directory is now /var/db/collectd
814 2004-07-10, Version 1.1: Minor changes
815 * Nothing really useful to say ;)
817 2004-07-09, Version 1.0: Initial Version
818 * The following modules are provided:
