2262 * collectd: Okay-notifications have been fixed. Thanks to Andrés J.
2263 Díaz for fixing this bug.
2264 * collectd: A programming error has been fixed in the notification
2265 code. The bug may result in an assertion failure.
2266 * memcached plugin: Portability fix for Solaris. Thanks to Amit Gupta
2267 for reporting the bug.
2269 2009-06-02, Version 4.6.3
2270 * Build system, various plugins: Many build fixes for FreeBSD,
2271 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
2272 for many fixes and providing a build system for many platforms,
2273 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
2274 providing an OpenBSD system.
2275 * collectd: Two bugs with the threshold checking have been fixed. The
2276 first one prevented thresholds to be checked at all, the second one
2277 caused wrong behavior with the persistency option. Thanks to Andrés
2278 J. Díaz for fixing these problems.
2279 * collectd: Handling of the `Include' configuration option has been
2281 * battery plugin: Don't complain about a missing directory every
2283 * exec plugin: Allow executed programs to close STDERR. Thanks to
2284 Thorsten von Eicken for reporting this problem.
2285 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
2286 Tomasz Pala for the patch.
2287 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for

2295 * filter subsystem: Allow `Chains' without default targets.
2296 * liboping: A patch to comply with strict aliasing rules has been
2298 * timediff match: Fix a typo: The match was registered with a wrong
2299 name which prevented this match to be used as documented. Thanks to
2300 Bruno Prémont for finding this problem.
2301 * bind plugin: Fix collection of the cached RR sets. The number of RR
2302 sets currently in the cache was collected as a counter value, which
2303 is nonsense. Thanks to Bruno Prémont for implementing this.
2304 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
2305 primarily BSDs, don't take it well and crash.
2306 * oracle plugin: Portability to 64 bit systems has been improved.
2307 * postgresql plugin: The default configuration has been improved.
2308 * rrdtool plugin: Fix a possible race condition: If the network plugin
2309 is brought and dispatches a value before the rrdtool plugin is
2310 initialized, the daemon may crash.
2312 2009-02-22, Version 4.6.1
2313 * collectd: Many documentation fixes.
2314 * Collectd::Unixsock: Error handling has been improved.
2315 * regex match: Don't link with the PCRE library.

2317 for finding and fixing most of them.
2318 * ipmi plugin: Fix an off-by-one error which could cause segmentation
2319 faults. Thanks to Peter Holik for his patch.
2321 2009-02-16, Version 4.6.0
2322 * collectd: Added the `filter chain' infrastructure, which allows the
2323 user to use `matches' and `targets' to control value processing.
2324 * collectd: The new `-T' command line argument allows more in-depth
2325 testing of a configuration. Thanks to Doug MacEachern for the patch.
2326 * collectd-nagios: The Nagios integration command has been updated to
2327 use libcollectdclient. The `percentage' aggregation function has
2328 been added. Thanks to Fabian Linzberger for the patch.
2329 * libcollectdclient: A library which abstracts communication with the
2330 unixsock plugin for clients has been added.
2331 * regex match: Match values by their identifies using regular
2333 * timediff match: Match for values with an invalid timestamp.
2334 * value match: Select values by their data sources' values.
2335 * notification target: Create and dispatch a notification.
2336 * replace target: Replace parts of an identifier using regular
2338 * set target: Set (overwrite) entire parts of an identifier.
2339 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
2340 statistics, allowing very detailed name server statistics. Thanks to
2341 Bruno Prémont for this plugin.
2342 * cpu plugin: Report `interrupt' separately when using
2343 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
2344 example for native OpenBSD support, has been added. Thanks to Simon
2345 Kuhnle for the patch.
2346 * csv plugin: Make it possible to write values to STDOUT instead of
2347 files. This is meant for testing purposes mostly. The output written
2348 to STDOUT is compatible with the exec plugin. Thanks to Doug
2349 MacEachern for the patch.
2350 * curl plugin: This new plugin can be used to read web pages and parse
2351 them using the same mechanism that's used in the tail plugin.
2352 * dbi plugin: This new plugin allows you to connect to a variety of
2353 relational databases and use SQL to gather custom statistics from
2354 it. It is similar to the already existing PostgreSQL plugin but uses
2355 libdbi to communicate with the database(s).
2356 * interface plugin: Use the ignorelist framework when selecting /
2357 ignoring interfaces. This allows one to use regular expressions to
2358 select interfaces, too.
2359 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
2360 Thanks to Bruno Prémont for this patch.
2361 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

2364 socket, too. Thanks to Mirko Buffoni for the patch.
2365 * network plugin: Further performance improvements for the receive
2366 code. This hopefully will help very large setups.
2367 * openvpn plugin: This new plugin collects statistics provided by the
2368 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
2369 * oracle plugin: This new plugin allows you to connect to an Oracle
2370 database and use SQL to gather custom statistics from it. It is
2371 similar to the already existing PostgreSQL plugin.
2372 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
2374 * perl plugin: Export the newly added plugin_write() to Perl plugins.
2375 * perl plugin: Added support for `notification meta data'.
2376 * perl plugin: Added support for the `filter chain' infrastructure by
2377 allowing plugins to register `matches' and `targets'.
2378 * postgresql plugin: The preferred configuration syntax has been
2379 updated to be in line with the syntax used by the new dbi and oracle
2380 plugins. The compatibility code for the old syntax is present.
2381 Support for the new `Result' blocks and the interval parameter has
2383 * processes plugin: Stacksize and virtual memory usage statistics have
2384 been added. Portability fixes.
2385 * rrdcached plugin: This new plugin uses the (still in development)
2386 RRD accelerator daemon, rrdcached. This daemon works very similar to
2387 the original rrdtool plugin of collectd, but adds some more nice
2389 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
2392 2009-05-09, Version 4.5.4
2393 * Build system, various plugins: Many build fixes for FreeBSD,
2394 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
2395 for many fixes and providing a build system for many platforms,
2396 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
2397 providing an OpenBSD system.
2398 * collectd: Fix a potential race condition when creating directories.
2399 * battery plugin: Don't complain about a missing directory every

2403 Thorsten von Eicken for reporting this problem.
2404 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
2405 Tomasz Pala for the patch.
2406 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
2408 * rrdtool plugin: Fix a possible race condition: If the network plugin
2409 is initialized and dispatches a value before the rrdtool plugin is
2410 initialized, the daemon may crash.
2411 * memory plugin: Fix a potential problem under Solaris.
2413 2009-02-22, Version 4.5.3
2414 * build system: The check for libupsclient even when `pkg-config' is
2416 * collectd: Fix error handling in the global cache.
2417 * Collectd::Unixsock: Error handling has been improved.
2418 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
2420 * ipmi plugin: Fix an off-by-one error which could cause segmentation
2421 faults. Thanks to Peter Holik for his patch.
2422 * tcpconns plugin: An endianness problem has been fixed in the *BSD
2423 code. Thanks to "thated" for reporting this.
2425 2009-01-02, Version 4.5.2
2426 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2427 file may be in both locations, especially when the database was
2428 installed in a non-standard path. Thanks to Dusty Doris for
2430 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2431 Solaris, in the configure script automatically.
2432 * build system, tcpconns plugin: Check for `kvm_nlist' and
2433 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
2434 library with similar functions to the BSD variant, but doesn't
2435 provide these necessary functions.
2436 * collectd.conf(5): Various fixes and clarifications.
2437 * collectd: Remove a GNUism (unnamed unions), thus improving
2439 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
2440 This solves portability problems, especially for Solaris.
2441 * dns plugin: Fix a portability problem with NetBSD.
2442 * filecount plugin: Fix an off-by-one error. This error may cause a
2444 * network plugin: Fix the handling of `type' in the network protocol.
2445 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2446 much larger buffer. This caused the `type' to be transferred much
2447 more often than necessary. In some cases, e. g. the `cpu' and
2448 `cpufreq' plugins being used at the same time, data may be corrupted
2449 in those files. Thanks to Bruno Prémont for debugging and reporting
2451 * processes plugin: Fix a possible segmentation fault when specifying
2452 invalid configuration options.
2453 * unixsock plugin: Make sure the initialization function is run only
2454 once. This resolves a file descriptor leak under systems which run
2455 the initialization more than once, such as Solaris.
2457 2008-10-16, Version 4.5.1
2458 * build system: Change `--enable-<plugin>' to abort with an error if
2459 dependencies are not met. Thanks to Bruno Prémont for the patch.
2460 Also, the poisoning of various string functions has been restricted
2462 * collectd: Fix a memory leak in the global value cache. With every
2463 *missing* value a couple of bytes would be leaked. Another memory
2464 leak in the configuration handling code has been fixed. Thanks to
2465 Niraj Tolia for reporting these issues.
2466 * collectd: Fix an off-by-one error in the ignorelist functionality.
2467 When using regular expressions, the last character would be missing,
2468 possibly matching differently from what one would expect.
2469 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2471 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2472 Linzberger for reporting the bug.
2473 * iptables plugin: Fix an off-by-one error. If a string was just one
2474 character too long, it was truncated instead of reporting an error.
2475 * network plugin: Fix a memory leak in the configuration handling
2476 code. Thanks to Niraj Tolia for reporting this issue.
2477 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2478 * postgresql plugin: Don't reopen connection during reinitialization.
2479 This fixes a bug under Solaris and potentially other platforms.
2480 Missing calls to `PQclear' have been added, too. This fixes memory
2481 leaks. Thanks to ``Admin'' for reporting these bugs.
2482 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
2484 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2485 problems with some `libc's. Thanks to Matthias Lay for reporting the
2488 2008-09-04, Version 4.5.0
2489 * collectd: Added the ability to flush certain identifiers.
2490 * collectd: The concept of `notification meta data' has been
2492 * filecount plugin: The new filecount plugin counts the number of
2493 files in a directory and its subdirectories.
2494 * ipmi plugin: Sensor names have been changed to ensure unique names.
2495 Notifications upon added and removed sensors can now be generated.
2496 * notify_desktop plugin: This new plugin sends notifications to the
2497 X desktop using the structure defined in the `Desktop Notification
2499 * notify_email plugin: This new plugin sends out notifications via
2500 email, using the `esmtp' library.
2501 * onewire plugin: The new experimental(!) onewire plugin reads values,
2502 such as temperatures, from sensors connected to the computer via the
2504 * perl plugin: Improved synchronized access to internal data structures
2505 and fixed a possible dead-lock.
2506 * perl plugin: Added the ability to flush certain identifiers and marked
2507 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
2509 * perl plugin: Added the ability to configure Perl plugins.
2510 * postgresql plugin: The new postgresql plugin collects statistics
2511 about or from a PostgreSQL database.
2512 * processes plugin: The `ProcessMatch' option has been added.
2513 * rrdtool plugin: Implement throttling of the `update queue' to lessen
2515 * tcpconns plugin: This plugin has been ported to OpenBSD.
2516 * thermal plugin: The new thermal plugin collects system temperatures
2517 using Linux ACPI thermal zone data.
2519 2009-01-02, Version 4.4.5
2520 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2521 file may be in both locations, especially when the database was
2522 installed in a non-standard path. Thanks to Dusty Doris for
2524 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2525 Solaris, in the configure script automatically.
2526 * collectd.conf(5): Various fixes and clarifications.
2527 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
2528 portability problems, especially for Solaris.
2529 * dns plugin: Fix a portability problem with NetBSD.
2530 * network plugin: Fix the handling of `type' in the network protocol.
2531 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2532 much larger buffer. This caused the `type' to be transferred much
2533 more often than necessary. In some cases, e. g. the `cpu' and
2534 `cpufreq' plugins being used at the same time, data may be corrupted
2535 in those files. Thanks to Bruno Prémont for debugging and reporting
2537 * unixsock plugin: Make sure the initialization function is run only
2538 once. This resolves a file descriptor leak under systems which run
2539 the initialization more than once, such as Solaris.
2541 2008-10-16, Version 4.4.4
2542 * build system: Change `--enable-<plugin>' to abort with an error if
2543 dependencies are not met. Thanks to Bruno Prémont for the patch.
2544 Also, the poisoning of various string functions has been restricted
2546 * collectd: Fix a memory leak in the global value cache. With every
2547 *missing* value a couple of bytes would be leaked. Another memory
2548 leak in the configuration handling code has been fixed. Thanks to
2549 Niraj Tolia for reporting these issues.
2550 * collectd: Fix an off-by-one error in the ignorelist functionality.
2551 When using regular expressions, the last character would be missing,
2552 possibly matching differently from what one would expect.
2553 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2555 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2556 Linzberger for reporting the bug.

2558 code. Thanks to Niraj Tolia for reporting this issue.
2559 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2560 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2561 problems with some `libc's. Thanks to Matthias Lay for reporting the
2564 2008-09-01, Version 4.4.3
2565 * collectd: Fix a memory leak in the threshold checking code.
2566 * memcached plugin: Fix a too short timeout and a related file
2568 * memory plugin: A typo in the libstatgrab code has been fixed.
2569 * snmp plugin: Fix a possible memory leak.
2571 2008-07-15, Version 4.4.2
2572 * build system: Use pkg-config to detect the upsclient library.
2573 * collectd: Try even harder to determine the endianness of the
2574 architecture collectd is being built on.
2575 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
2577 * dns plugin: Fix compilation errors with BIND versions 19991001
2579 * network plugin: Bugfix in the init routine: The init function
2580 cleared a buffer regardless of its contents. This could lead to lost
2581 values under Solaris.
2582 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
2583 * vserver plugin: Remove usage of the thread-unsafe `readdir'
2585 * wireless plugin: Work around incorrect noise and power values
2586 returned by some broken drivers.
2588 2008-06-03, Version 4.4.1
2589 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
2590 to kyrone for reporting this.
2591 * collectd: Fixed min/max output in notifications generated by
2593 * collectd-nagios: Fix the protocol used to communicate with the
2595 * perl plugin: Fail noisily, but don't shutdown the daemon, if
2596 initialization has errors. An issue with Perl 5.10 has been fixed.
2597 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
2598 René Rebe and Siegmund Gorr for reporting this.
2600 2008-05-06, Version 4.4.0
2601 * collectd: Internal code cleanups.
2602 * collectd: Added support for a `Flush' command in the unixsock and
2603 exec plugins. This command can be used to force a plugin (or all) to
2604 flush its values to disk.
2605 * collectd: Thresholds can now be configured to apply to one data
2606 source only, making it possible to configure different thresholds
2607 for each data source.
2608 * apache, nginx plugins: Added the possibility to disable host and/or
2610 * ascent plugin: The new ascent plugin reads and parses the statistics
2611 page of an Ascent server.

2617 sensor values via IPMI, the intelligent platform management
2619 * iptables plugin: The iptc library that is used by the iptables
2620 plugin has been added to the distribution, because it is not
2621 provided by all distributions and removed from at least one.
2622 * powerdns plugin: The new powerdns plugin reads statistics from an
2623 authoritative or a recursing PowerDNS name server.
2624 * rrdtool plugin: The size of the files generated with the default
2625 configuration has been decreased.
2626 * tail plugin: The new tail plugin can be used to gather statistics by
2627 continuously reading from log files.
2628 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
2629 TeamSpeak2 server and collects statistics about the number of users
2630 and number of channels.
2631 * users plugin: Support for the statgrab library has been added.
2632 * vmem plugin: The new vmem plugin collects very detailed statistics
2633 about the virtual memory subsystem of Linux.

2657 if the libc expects it.
2658 * collectd: Error and warning messages have been improved.
2659 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2661 * apache plugin: Allocate new memory when reading a webpage instead of
2662 using a buffer of static size.
2663 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2665 * hddtemp plugin: Error and warning messages have been improved.

2671 * collectd: Fix handling of missing values in the global value cache.
2672 * collectd: Improved error messages when parsing the configuration.
2673 * sensors plugin: Fix temperature collection with libsensors4.
2674 * unixsock plugin: Fix mixed input and output operation on streams.
2675 * wireless plugin: Fix reading noise value.
2677 2008-03-05, Version 4.3.1
2678 * exec plugin: Set supplementary group IDs.
2680 + Use `memcpy' when constructing/parsing a package to avoid
2681 alignment problems on weird architectures, such as Sparc.
2682 + Translate doubles to/from the x86 byte representation to ensure
2683 cross-platform compatibility.
2684 * ping plugin: Correct the handling of the `TTL' setting.
2685 * swap plugin: Reapply a patch for Solaris.
2686 * tcpconns plugin: Portability improvements.
2688 2008-02-18, Version 4.3.0
2689 * collectd: Notifications have been added to the daemon. Notifications
2690 are status messages that may be associated with a data instance.
2691 * collectd: Threshold checking has been added to the daemon. This
2692 means that you can configure threshold values for each data
2693 instance. If this threshold is exceeded a notification will be
2695 * collectd: The new `FQDNLookup' option tells the daemon to use the
2696 full qualified domain name as the hostname, not just the host part
2697 es returned by `gethostname(2)'.
2698 * collectd: Support for more than one `TypesDB' file has been added.
2699 This is useful when one such file is included in a package but one
2700 wants to add custom type definitions.
2701 * collectd: The `Include' config option has been expanded to handle
2702 entire directories and shell wildcards.
2703 * collectdmon: The new `collectdmon' binary detects when collectd
2704 terminates and automatically restarts it again.
2705 * csv plugin: The CSV plugin is now able to store counter values as a
2706 rate, using the `StoreRates' configuration option.
2707 * exec plugin: Handling of notifications has been added and the
2708 ability to pass arguments to the executed programs has been added.
2709 * hddtemp plugin: The new `TranslateDevicename' option lets you
2710 disable the translation from device names to major-minor-numbers.
2711 * logfile plugin: Handling of notifications has been added.
2712 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
2713 domain name lookups in this plugin.
2714 * perl plugin: Many internal changes added support for handling multiple
2715 threads making the plugin reasonably usable inside collectd. The API has
2716 been extended to support notifications and export global variables to
2717 Perl plugins; callbacks now have to be identified by name rather than a
2718 pointer to a subroutine. The plugin is no longer experimental.
2719 * uuid plugin: The new UUID plugin sets the hostname to an unique
2720 identifier for this host. This is meant for setups where each client
2721 may migrate to another physical host, possibly going through one or
2722 more name changes in the process. Thanks to Richard Jones from
2723 Red Hat's Emerging Technology group for this plugin.
2724 * libvirt: The new libvirt plugin uses the `libvirt' library to query
2725 CPU, disk and network statistics about guest systems on the same
2726 physical server. Thanks to Richard Jones from Red Hat's Emerging
2727 Technology group for this plugin.
2729 2008-04-22, Version 4.2.7
2730 * build system: Improved detection of several libraries, especially if
2731 they are in non-standard paths.
2732 * build system: Portability fixes: Automatically define "_REENTRANT"
2733 if the libc expects it.
2734 * collectd: Error and warning messages have been improved.
2735 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2737 * apache plugin: Allocate new memory when reading a webpage instead of
2738 using a buffer of static size.
2739 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2741 * hddtemp plugin: Error and warning messages have been improved.
2742 * sensors plugin: Fix sensor collection for some chip types.
2744 2008-03-29, Version 4.2.6

2746 * sensors plugin: Fix temperature collection with libsensors4.
2747 * unixsock plugin: Fix mixed input and output operation on streams.
2748 * wireless plugin: Fix reading noise value.
2750 2008-03-04, Version 4.2.5
2751 * apache plugin: Improved initialization and error messages.
2752 * exec plugin: Set supplementary group IDs.
2754 + Create separate threads for reading from the socket and parsing
2755 and dispatching incoming packets. Versions prior to this may have
2756 problems in high-load situations, where the socket receive buffers
2757 overflows, resulting in gaps in the data.
2758 + Use `memcpy' when constructing/parsing a package to avoid
2759 alignment problems on weird architectures, such as Sparc.
2760 + Translate doubles to/from the x86 byte representation to ensure
2761 cross-platform compatibility.
2762 * ping plugin: Correct the handling of the `TTL' setting.
2763 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
2764 * swap plugin: Reapply a patch for Solaris.
2765 * tcpconns plugin: Portability improvements.
2767 2008-01-21, Version 4.2.4
2768 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2769 the permission on the socket as documented in the manpage. Thanks to
2770 Evgeny Chukreev for fixing this issue.
2771 * collectd: The documentation has been improved.
2773 2007-12-28, Version 4.2.3
2774 * sensors plugin: Updated the plugin to build and work with version 3
2775 of the libsensors library.
2777 2007-12-15, Version 4.2.2
2778 * nginx plugin: Incorrect comparison of strings lead to a segfault
2779 when using the plugin. Thanks to Saulius Grigaliunas for fixing
2781 * logfile plugin: The config option `Timestamp' was handled
2782 incorrectly and basically always active. Thanks to Luke Heberling
2785 2007-11-08, Version 4.2.1
2786 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
2787 enabled on the host.
2788 * snmp plugin: Fix a memory leak.
2790 2007-10-27, Version 4.2.0
2791 * collectd: The new config option `Include' lets you include other
2792 configfiles and thus split up your config into smaller parts. This
2793 may be especially interesting for the snmp plugin to keep the data
2794 definitions separate from the host definitions.
2795 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
2796 (number of connections, octets and packets for each service and
2797 destination). Thanks to Sebastian Harl for this plugin.
2798 * memcached plugin: The new `memcached' plugin connects to a memcached
2799 daemon process and collects statistics of this distributed caching
2800 system. Thanks to Antony Dovgal for contributing this plugin.
2801 * nginx plugin: The new `nginx' plugin reads the status page of an
2802 nginx daemon and saves the handled connections and requests.
2803 * perl plugin: Many changes, including the added `EnableDebugger'
2804 config option which lets you debug your Perl plugins more easily.
2805 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2806 be more thread-safe otherwise by locking calls to the library.
2807 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
2808 correct the values returned by SNMP-agents. If a <data> block is
2809 defined as `table' the instance is now optional. The sequence number
2810 is used as the type-instance in this case. The new `InstancePrefix'
2811 option allows to add arbitrary prefixes to the type-instance.
2812 * tcpconns plugin: The new `tcpconns' plugin collects the number of
2813 certain TCP connections and what state they're in. This can be used
2814 to see how many connections your FTP server has to handle or how
2815 many outgoing connections your mailserver has open.
2817 2008-01-11, Version 4.1.6
2818 * unixsock plugin: A bug in the unixsock plugin caused it not to set

2821 * collectd: The documentation has been improved.
2823 2007-12-27, Version 4.1.5
2824 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
2826 * sensors plugin: Updated the plugin to build and work with version 3
2827 of the libsensors library.
2829 2007-11-08, Version 4.1.4
2830 * Build system: Improve detection of the rrd library, especially if
2831 it's in a non-standard location.
2832 * Build system: A bug when parsing the argument for
2833 `--with-libnetsnmp' has been fixed.
2834 * collectd: Implement `strerror_r' if the libc doesn't provide it.
2835 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
2836 a deadlock or delay when shutting down the daemon.
2837 * snmp plugin: Fix a memory leak.
2839 2007-10-24, Version 4.1.3
2840 * collectd: A build issue under Solaris has been resolved by renaming
2842 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2843 be more thread-safe otherwise by locking calls to the library.
2845 2007-09-28, Version 4.1.2
2846 * apcups plugin: Fix reporting of the `load percent' data.
2847 * wireless plugin: Correct the handling of cards returning signal and
2848 noise quality as percentage.
2849 * perl plugin: Fix a possible buffer overflow in get_module_name().
2850 * build system: Further improve the detection of libraries.
2851 * netlink plugin: Build issues under some older versions of the Linux
2852 includes (i. e. Debian Sarge) have been fixed.
2853 * snmp plugin: Fix a potential segfault when a host times out. Add
2854 support for the `timeticks' type.
2856 2007-09-12, Version 4.1.1
2857 * Build system: The detection of `libnetlink' has been improved.
2858 * collectd: The documentation has been fixed in numerous places.
2859 * exec plugin: Setting the group under which to run a program has been
2861 * collectd: The `sstrerror' function was improved to work correctly
2862 with the broken GNU version of `strerror_r'.
2863 * collectd: Write an error message to STDERR when loading of a plugin
2865 * apcups plugin: Fix the `types' used to submit the values: They still
2866 has an `apcups_' prefix which doesn't work anymore.
2867 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2868 whatever the client thinks is `now'..
2870 2007-09-01, Version 4.1.0
2871 * Build system: The build system has been changed to automatically
2872 disable all plugins, which are missing dependencies. The dependency
2873 checking has been removed from the plugins themselves to remove
2875 * Flexible interval: The interval of collected data is now sent along
2876 with the data itself over the network, so that the interval-settings
2877 of server and clients no longer needs to match.
2878 * netlink plugin: The new `netlink' plugin connects to the Linux
2879 kernel using a netlink socket and uses it to query information about
2880 interfaces, qdiscs and classes.
2881 * rrdtool plugin: The cache is now dumped to disk in an extra thread
2882 to not block data collection.
2883 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
2884 network devices, such as switches, routers, thermometers, rack
2885 monitoring servers, etc. The collectd-snmp(5) manpage documents this
2887 * unixsock plugin: Added the `LISTVAL' command.
2888 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
2889 of music played with xmms.
2891 2007-09-28, Version 4.0.9
2892 * apcups plugin: Fix reporting of the `load percent' data.
2893 * wireless plugin: Correct the handling of cards returning signal and
2894 noise quality as percentage.
2895 * perl plugin: Fix a possible buffer overflow in get_module_name().
2897 2007-09-12, Version 4.0.8
2898 * collectd: The `sstrerror' function was improved to work correctly
2899 with the broken GNU version of `strerror_r'.
2900 * collectd: Write an error message to STDERR when loading of a plugin
2902 * apcups plugin: Fix the `types' used to submit the values: They still
2903 has an `apcups_' prefix which doesn't work anymore.
2904 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2905 whatever the client thinks is `now'..
2907 2007-08-26, Version 4.0.7
2908 * documentation: Some typos have been fixed and some information has
2910 * build system: Many fixes for detecting libraries in unusual places,
2911 such as on RedHat systems. The affected libraries are `libcurl',
2912 `libmysql', and `libupsclient'.
2913 * network plugin: Allow the `Port' option to be specified as a number
2914 (i. e. without quotes).
2915 * nut plugin: A fix allows linking the nut plugin against
2916 libupsclient, version >= 2.2.0.
2917 * processes plugin: Fix a potential segmentation fault.
2919 2007-07-30, Version 4.0.6
2920 * sensors plugin: Fix the ignorelist functionality: Only the `type
2921 instance' was used to match against the list, but the documentation
2922 told otherwise. This release fixes the code, so it complies with the
2924 * syslog plugin: Call `openlog' right when the plugin is loaded, so
2925 configuration messages will end up in the logging facility.
2926 * conrtib/fedora: The contributed specfile for Fedora has been
2929 2007-07-05, Version 4.0.5
2930 * Portability: More fixes for OpenBSD have been included.
2932 2007-06-24, Version 4.0.4
2933 * cpu plugin: Fixed the Solaris code.
2934 * dns plugin: Fixed a build issue for OpenBSD.
2935 * interface plugin: Fixed the Solaris code.
2936 * load plugin: Fixed the alternative `/proc' Linux code.
2937 * memory plugin: Fixed the Solaris code.
2938 * oconfig: Don't require `-lfl' anymore.
2940 2007-06-19, Version 4.0.3
2941 * cpu plugin: Fix the Darwin / Mac OS X code.
2942 * ping plugin: Use the return value of `getpid', not its address.
2943 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
2944 initialized correctly.
2945 * configure: Added `--with-nan-emulation' to aid cross compilation.
2947 2007-06-12, Version 4.0.2
2948 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
2949 they're given in numerically form.
2951 2007-06-07, Version 4.0.1
2952 * iptables plugin: A bug in the configuration routine has been fixed.
2953 Setting a comment in the configfile will no longer cause a
2956 2007-06-03, Version 4.0.0
2957 * collectd: The plugin-infrastructure has been changed to allow for
2958 more types of plugins, namely `write' and `log' plugins.
2959 * collectd: The read-function has been changed to read many plugins in
2960 parallel, using threads. Thus, plugins generally need to use
2961 thread-safe functions from now on.
2962 * collectd: The '-t' command line options allows to perform syntax tests
2963 of the configuration file and exit immediately.
2964 * csv plugin: The new `csv' plugin handles output to `comma separated
2966 * rrdtool plugin: The new `rrdtool' plugin handles output to
2967 RRD-files. Data can be cached to combine multiple updates into one
2968 write to increase IO-performance.
2969 * network plugin: The new `network' plugin handles IO via the network.
2970 It implements a different, much more extensible protocol which can
2971 combine many values in one packet, decreasing the number of UDP-
2972 packets being sent. It can read from and send to the network and
2973 with the appropriate configuration even forward packets to other
2975 * unixsock plugin: The new `unixsock' plugin provides an interface to
2976 communicate with the daemon while it is running. Right now the
2977 commands `GETVAL' and `PUTVAL' are implemented, but more are to
2979 * perl plugin: The new `perl' plugin allows you to write extensions
2980 for collectd in the scripting-language Perl.
2981 * logfile plugin: The new `logfile' plugin writes logmessages to files
2982 or STDOUT or STDERR.
2983 * syslog plugin: The new `syslog' plugin sends logmessages to the
2984 system's syslog daemon.
2985 * entropy plugin: The new `entropy' plugin collects the amount of
2986 entropy currently being available to the system.
2987 * exec plugin: The new `exec' plugin forks child processes and reads
2988 back values provided by the forked processes.
2989 * iptables plugin: The new `iptables' plugin reads counters from
2990 iptables rules. Thanks to Sjoerd van der Berg for contributing this
2992 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
2993 to Peter Holik for contributing this plugin.
2994 * nut plugin: The new `nut' plugin connects the upsd of the `network
2995 ups tools' and reads information about the connected UPS.
2996 * apache plugin: Support for lighttpd's `BusyServers' (aka.
2997 connections) field was added by Florent Monbillard.
2998 * collectd-nagios: The new `collectd-nagios' binary queries values
2999 from collectd, parses them and exits according to Nagios-standards.
3000 * manpages: The manpages have been improved a lot.
3002 2007-09-28, Version 3.11.7
3003 * wireless plugin: Correct the handling of cards returning signal and
3004 noise quality as percentage.
3006 2007-08-31, Version 3.11.6
3007 * processes plugin: Fix a potential segmentation fault.
3009 2007-05-29, Version 3.11.5
3010 * configure: Added `AC_SYS_LARGEFILE' for LFS.
3011 * ntpd plugin: Fix a potential buffer overflow.
3012 * processes plugin: Fix a bug when run under Linux 2.4. All processes
3013 were accounted as `zombies'.
3015 2007-04-10, Version 3.11.4
3016 * dns plugin: Change the order of includes to make the plugin compile
3019 2007-03-30, Version 3.11.3
3020 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
3021 of the unused `COLLECT_KSTAT'.
3023 2007-02-11, Version 3.11.2
3024 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
3025 NULL-pointer may have been passed to `printf' which causes a
3026 segfault with some libcs.
3028 2007-02-10, Version 3.11.1
3029 * df plugin: Some wrong defines have been fixed so the plugin works
3030 under Solaris again.
3031 * dns plugin: The usage of a struct has been fixed to work with
3033 * processes plugin: Some missing defines have been added so the plugin
3034 compiles cleanly under FreeBSD and presumably other UNIXes.
3036 2006-12-22, Version 3.11.0
3037 * collectd: The new command line option `-P' makes it easier for
3038 distributors to change the location of PID-files.
3039 * collectd: The daemon shuts down faster now which makes it easier to
3040 write init.d-scripts for it.
3041 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
3042 caused problems every now and then.
3043 * df plugin: New config options allow to ignore certain mountpoints,
3044 filesystem types or devices.
3045 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
3046 and interprets it. It collects traffic as well as qtype, opcode and
3048 * email plugin: Sebastian Harl has contributed this plugin which
3049 counts received mails in categories (e. g. ham, spam, virus), spam
3050 score (as given by SpamAssassin) and check types.
3051 * mbmon plugin: Flavio Stanchina has contributed this plugin which
3052 uses `mbmon' to gather information from sensors on the motherboard.
3053 * processes plugin: Collect detailed statistics for configured
3054 processes, that's process and thread count, CPU usage, resident
3055 segment size and pagefaults.
3056 * multimeter plugin: Peter Holik contributed a new plugin which
3057 queries multimeters.
3058 * sensors plugin: Lubos Stanek has put much effort into improving this
3059 plugin, including `extended naming', collection of voltage values
3060 and the possibility to ignore certain values.
3062 2006-12-21, Version 3.10.4
3063 * Max Kellermann has identified a bug in the server routine: When
3064 opening a socket fails the daemon will (re)try opening the socket in
3065 an endless loop, ultimately leading to a `EMFILE' error.
3067 2006-11-04, Version 3.10.3
3068 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
3069 ntpd's reply was sent in more than one packet, the buffer size was
3070 calculated incorrectly, resulting in the reading of uninitialized or
3073 2006-11-01, Version 3.10.2
3074 * The sample config file has been improved.
3075 * Errors in the manpages have been corrected.
3076 * The ping-plugin now adds hosts during initialization, not during
3077 startup. This speeds up startup when no network connectivity is
3078 available. Also, the hosts are being added later when the network is
3080 * Improved BSD-support for the df-plugin.
3081 * Fixed syntax errors in the swap-plugin for Mac OS X.
3082 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
3084 * Don't disable the mysql-plugin if connecting to the database fails
3085 during initialization. Instead, try again in increasing intervals.
3087 2006-07-19, Version 3.10.1
3088 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
3089 the apcups cannot be reached, unconnected sockets will pile up and
3090 eventually lead to `Too many open files' errors.
3092 2006-07-09, Version 3.10.0
3093 * The `disk' plugin has been ported to Darwin.
3094 * The `battery' plugin should work on many Apple computers now.
3095 * The `traffic' plugin can now ignore certain interfaces. Also,
3096 statistics for sent/received packets and errors have been added.
3097 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
3098 to Anthony Gialluca for contributing this plugin and providing me
3099 with a test environment :)
3100 * A plugin for monitoring an NTP instance and the local clock drift
3103 2006-06-25, Version 3.9.4
3104 * The Solaris code in the `swap' plugin has been changed to reflect
3105 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
3107 * The debugging system has been fixed to work with the Sun libc.
3108 * When built without librrd the variable `operating_mode' could be
3109 uninitialized. Thanks to David Elliot for reporting the bug.
3111 2006-06-01, Version 3.9.3
3112 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
3113 operating systems also profit from the changes, but I wasn't able to
3115 * Changed the build system to find the netinet-includes under FreeBSD
3116 and therefore successfully build the `liboping' library there.
3118 2006-05-09, Version 3.9.2
3119 * Applied a patch to the `liboping' library. Due to a bug in the
3120 sequence checking the `ping' plugin stopped working after
3121 approximately 7.6 days.
3123 2006-05-09, Version 3.8.5
3124 * Applied a patch to the `liboping' library. Due to a bug in the
3125 sequence checking the `ping' plugin stopped working after
3126 approximately 7.6 days.
3128 2006-04-21, Version 3.9.1
3129 * Build issues with Solaris and possible other architectures have been
3131 * Problems when building the `apache'-plugin without `libcurl' have
3133 * A bug in the `ping' plugin has been fixed. Sorry folks.
3135 2006-04-02, Version 3.9.0
3136 * A plugin to monitor the Apache webserver has been added.
3137 <http://httpd.apache.org/>
3138 * A plugin to collect statistics about virtual servers using VServer.
3139 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
3141 * A plugin for wireless LAN cards has been added. It monitors signal
3142 strength, link quality and noise ratio..
3143 * A plugin for Apple hardware sensors has been added.
3144 * An option to compile collectd with different `step' and `heartbeat'
3145 settings has been added. The size of RRAs is no longer static but
3146 calculated based on the settings for `step' and `width'.
3147 * The `ping' plugin can now be configured to use a certain TTL.
3148 * A plugin to monitor the hardware sensors of Apple computers has been
3150 * The plugins `cpu', `memory', `processes' and `traffic' have been
3151 ported to Mach/Darwin (Mac OS X).
3152 * The `log mode' has been contributed by Christophe Kalt. It writes
3153 the data into text files rather than RRD files.
3155 2006-04-09, Version 3.8.4
3156 * Applied patch by Vincent Stehlé which improves the disk-name
3157 resolution in the `hddtemp' plugin for Linux systems.
3159 2006-04-02, Version 3.8.3
3160 * Applied a patch by James Byers: The MySQL plugin was not working
3161 with MySQL 5.0.2 or later.
3163 2006-03-14, Version 3.8.2
3164 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
3165 the GNU libc, because it points to `/etc/fstab' rather than
3168 2006-03-13, Version 3.8.1
3169 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
3170 * Fixes in the debian `postinst' and `init.d' scripts.
3172 2006-03-09, Version 3.8.0
3173 * The `ping' plugin no longer uses `libping' but a self written
3174 library named `liboping'. With this library it's possible to ping
3175 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
3177 2006-02-18, Version 3.7.2
3178 * A simple bug in the `battery' plugin has been fixed. It should now
3179 work with ACPI based batteries as well. Thanks to Sebastian for
3181 * Fixing a bug that prevented collectd to be built without librrd.
3182 Thanks to Werner Heuser for reporting it.
3184 2006-02-04, Version 3.7.1
3185 * The new network code has been improved to build with older versions
3187 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
3188 to Tommie Gannert for this patch.
3190 2006-01-30, Version 3.7.0
3191 * The `battery' plugin has been added. It collects information about
3193 * The MySQL plugin has been improved: It now writes two more RRD
3194 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
3195 * The `cpufreq' plugin now reads another file since the file it did
3196 read so far causes much overhead in the kernel. Also, you need root
3197 to read the old file, but not to read the new one.
3198 * The `hddtemp' plugin can now be configured to connect to another
3199 address and/or port than localhost.
3200 * The `df' plugin now prefers `statvfs' over `statfs'.
3201 * The network code has been rewritten. collectd now supports unicast
3202 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
3203 be set in the configfile.
3205 2006-01-24, Version 3.6.2
3206 * Due to a bug in the configfile handling collectd wouldn't start in
3207 client mode. This released fixes this.
3209 2006-01-20, Version 3.6.1
3210 * Due to a bug in `configure.in' all modules and the binary were
3211 linked against `libmysqlclient'. This issue is solved by this
3214 2006-01-17, Version 3.6.0
3215 * A config file has been added. This allows for loading only specific
3217 * A `df' plugin has been added.
3218 * A `mysql' plugin has been added.
3219 * The `ping' plugin doesn't entirely give up hope when a socket error
3220 occurred, but will back of and increase the intervals between tries.
3222 2006-01-21, Version 3.5.2
3223 * Fixed yet another bug in the signal handling.. Stupid typo..
3224 * Improved the ping plugin to not give up on socket errors (backport
3227 2005-12-18, Version 3.5.1
3228 * The PID-file is now deleted correctly when shutting down the daemon.
3229 * SIGINT and SIGTERM are now handled correctly.
3231 2005-12-16, Version 3.5.0 (Revision 326)
3232 * A bug in the `load' module under Solaris has been fixed.
3233 * The `users' module has been contributed by Sebastian Harl. It counts
3234 currently logged in users.
3235 * The CPU module now works under FreeBSD without the use of
3236 `libstatgrab', however SMP support is missing.
3237 * The default directories for the RRD files and the PID file now
3238 depend on the compile time setting of `localstatedir'.
3240 2005-11-15, Version 3.4.0 (Revision 236)
3241 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
3242 from gentoo's bugzilla for writing the patch.
3243 * The build dependency for librrd has been removed. Binaries built
3244 without librrd are client-only and will multicast their value as
3245 with the `-c' argument.
3246 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
3247 * The newly introduced `-f' switch prevents daemon initialization
3248 (forking, closing standard filehandles, etc.) Thanks to Alvaro
3249 Barcellos for this patch.
3251 2005-11-04, Version 3.3.0 (Revision 216)
3252 * New modules have been added:
3253 - `serial', for monitoring traffic on the serial interfaces
3254 - `nfs', for graphing NFS procedure calls
3255 - `tape', traffic from/to tape devices
3256 * The memory.rrd now accepts more than 4Gig of memory.
3258 2005-10-26, Version 3.2.0 (Revision 200)
3259 * Support for graphing the processes has been added (thanks to Lyonel
3261 * If reading from hddtemp fails collectd will increase the time
3262 between polls up to one day.
3263 * The init.d files have been improved.
3264 * Problems with the spec file have been fixed.
3266 2005-10-16, Version 3.1.0 (Revision 194)
3267 * Added the `setsid' syscall to the startup code.
3268 * Support for hddtemp has been added (thanks to Vincent Stehlé)
3270 2005-09-30, Version 3.0.0 (Revision 184)
3271 * The ability to send/receive data to/from the network (think
3272 multicast) has been added.
3273 * Modules have been split up into shared libraries can be loaded at
3274 runtime. The biggest advantage is that the core program doesn't need
3275 to be linked against an external library.
3276 * A patch by George Kargiotakis has been applied: It fixes the sensors
3277 behaviour then more than one sensor is being queried.
3279 2005-09-16, Version 2.1.0 (Revision 172)
3280 * A module for swap statistics has been added.
3282 2005-09-09, Version 2.0.0 (Revision 135)
3283 * Filenames can no longer be configured at program startup. The only
3284 options as of this version are the directory and ping hosts.
3285 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
3286 Soft-IRQ statistics are added to `System'.
3287 * Diskstats now collect read and write bytes, not sectors.
3288 * Ping statistics can now be collected for more than one host. There
3289 is no default any more: If no host is given no host will be pinged.
3290 * A self-written patch for libping has been applied so it builds
3293 2005-09-01, Version 1.8.1 (Revision 123)
3294 * Much improved configure-script: libraries and features may now be
3296 * More detailed warnings/error messages when RRD update fails.
3298 2005-08-29, Version 1.8.0:
3299 * Support for collecting disk statistics under Solaris.
3301 2005-08-25, Version 1.7.0:
3302 * Support for libstatgrab[1] for load, memory usage and network
3303 traffic. CPU- and disk-usage are not (yet) supported, since
3304 libstatgrab returns insufficient information. I will contact the
3306 * Improved the CPU-initialization code for Solaris. Apparently CPUs
3307 aren't necessarily counted linear which is now handled correctly.
3308 [1]: http://www.i-scream.org/libstatgrab/
3310 2005-08-21, Version 1.6.0:
3311 * Basic support for Solaris: System load and cpu-usage can be
3312 collected under Solaris, too. Other stats will follow later.
3313 * Many fixes in the autoconf-script
3314 * Collection/Museum scripts have been added under contrib/museum
3315 * collectd may now be started in unprivileged mode, though ping
3316 statistics will not work.
3318 2005-07-17, Version 1.5.1:
3319 * Diskstats-RRDs now use major/minor for naming. Some systems have
3320 weird strings as disk-names..
3322 2005-07-17, Version 1.5:
3323 * A new module, diskstats, has been added. It collects information
3324 about the disks and partitions.
3326 2005-07-11, Version 1.4.2:
3327 * The meminfo module has been changed to work with more platforms
3328 and/or kernel versions.
3330 2005-07-10, Version 1.4.1: Correct traffic stats
3331 * The traffic rrd-file is now created with DS-type `COUNTER' which I
3332 forgot to correct when I changed that module.
3334 2005-07-09, Version 1.4: More traffic stats
3335 * Traffic is now collected for all interfaces that can be found
3336 * Temperature-statistics are read from lm-sensors if available
3338 2005-07-08, Version 1.3: CPU stats
3339 * Collecting CPU statistics now
3341 2005-07-12, Version 1.2: Using syslog
3342 * collectd is now using the syslog facility to report errors, warnings
3344 * The default directory is now /var/db/collectd
3346 2005-07-10, Version 1.1: Minor changes
3347 * Nothing really useful to say ;)
3349 2005-07-09, Version 1.0: Initial Version
