+ * java plugin: Delay creating the JVM until after the daemon has
+ forked. The JVM internally creates threads that are lost when
+ forking. This means that Java-based plugins are now configured
+ during the init-phase, i. e. later than other plugins.
+ * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
+ to Alan Pevec for the patch.
+ * network plugin: Fix the handling of the “CacheFlush” option: The

+ * liboping: A patch to comply with strict aliasing rules has been
+ added.
+ * timediff match: Fix a typo: The match was registered with a wrong
+ name which prevented this match to be used as documented. Thanks to
+ Bruno Prémont for finding this problem.
+ * bind plugin: Fix collection of the cached RR sets. The number of RR
+ sets currently in the cache was collected as a counter value, which
+ is nonsense. Thanks to Bruno Prémont for implementing this.

+ primarily BSDs, don't take it well and crash.
+ * oracle plugin: Portability to 64 bit systems has been improved.
+ * postgresql plugin: The default configuration has been improved.
+ * rrdtool plugin: Fix a possible race condition: If the network plugin

+
+2009-02-22, Version 4.6.1
+ * collectd: Many documentation fixes.

+ MacEachern for the patch.
+ * curl plugin: This new plugin can be used to read web pages and parse
+ them using the same mechanism that's used in the tail plugin.
+ * dbi plugin: This new plugin allows you to connect to a variety of
+ relational databases and use SQL to gather custom statistics from
+ it. It is similar to the already existing PostgreSQL plugin but uses
+ libdbi to communicate with the database(s).

+ ignoring interfaces. This allows one to use regular expressions to
+ select interfaces, too.
+ * ipmi plugin: Handle temporary IPMI error conditions more gracefully.

+ * filecount plugin: Fix an off-by-one error. This error may cause a
+ segmentation fault.
+ * network plugin: Fix the handling of `type' in the network protocol.
+ Due to a programming mistake, only 4 or 8 bytes would be copied to a
+ much larger buffer. This caused the `type' to be transferred much
+ more often than necessary. In some cases, e. g. the `cpu' and
+ `cpufreq' plugins being used at the same time, data may be corrupted
+ in those files. Thanks to Bruno Prémont for debugging and reporting
+ this issue.
+ * processes plugin: Fix a possible segmentation fault when specifying
+ invalid configuration options.
+ * unixsock plugin: Make sure the initialization function is run only

+ Also, the poisoning of various string functions has been restricted
+ to debug builds.
+ * collectd: Fix a memory leak in the global value cache. With every
+ *missing* value a couple of bytes would be leaked. Another memory
+ leak in the configuration handling code has been fixed. Thanks to
+ Niraj Tolia for reporting these issues.
+ * collectd: Fix an off-by-one error in the ignorelist functionality.
+ When using regular expressions, the last character would be missing,
+ possibly matching differently from what one would expect.
+ * collectdmon: Don't block SIGCHLD. This fixes a potential portability
+ problem.
+ * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
+ Linzberger for reporting the bug.
+ * iptables plugin: Fix an off-by-one error. If a string was just one

+ code. Thanks to Niraj Tolia for reporting this issue.
+ * perl plugin: Log an error message if bootstrapping `Collectd' fails.
+ * postgresql plugin: Don't reopen connection during reinitialization.

+ leaks. Thanks to ``Admin'' for reporting these bugs.
+ * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
+ library.

+ source only, making it possible to configure different thresholds
+ for each data source.
+ * apache, nginx plugins: Added the possibility to disable host and/or
+ peer verification.
+ * ascent plugin: The new ascent plugin reads and parses the statistics
+ page of an Ascent server.

+ * disk plugin: The possibility to ignore certain disks or collect only
+ specific disks has been added.
+ * disk plugin: Support for the statgrab library has been added.
+ * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
+ sensor values via IPMI, the intelligent platform management
+ interface.
+ * iptables plugin: The iptc library that is used by the iptables
+ plugin has been added to the distribution, because it is not
+ provided by all distributions and removed from at least one.
+ * powerdns plugin: The new powerdns plugin reads statistics from an
+ authoritative or a recursing PowerDNS name server.
+ * rrdtool plugin: The size of the files generated with the default
+ configuration has been decreased.
+ * tail plugin: The new tail plugin can be used to gather statistics by
+ continuously reading from log files.

+ * wireless plugin: A work-around for broken wireless drivers has been
+ added.
+
+2008-04-22, Version 4.3.3
+ * build system: Improved detection of several libraries, especially if
+ they are in non-standard paths.
+ * build system: Portability fixes: Automatically define "_REENTRANT"
+ if the libc expects it.
+ * collectd: Error and warning messages have been improved.
+ * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
+ using them.
+ * apache plugin: Allocate new memory when reading a webpage instead of
+ using a buffer of static size.
+ * exec plugin: Close (almost) all filedescriptors before exec(2)ing
+ the program.
+ * hddtemp plugin: Error and warning messages have been improved.
+ * sensors plugin: Fix sensor collection for some chip types.

+ * tcpconns plugin: Portability improvements.
+
+2008-02-18, Version 4.3.0
+ * collectd: Notifications have been added to the daemon. Notifications
+ are status messages that may be associated with a data instance.
+ * collectd: Threshold checking has been added to the daemon. This
+ means that you can configure threshold values for each data
+ instance. If this threshold is exceeded a notification will be
+ created.
+ * collectd: The new `FQDNLookup' option tells the daemon to use the
+ full qualified domain name as the hostname, not just the host part
+ es returned by `gethostname(2)'.
+ * collectd: Support for more than one `TypesDB' file has been added.
+ This is useful when one such file is included in a package but one
+ wants to add custom type definitions.
+ * collectd: The `Include' config option has been expanded to handle
+ entire directories and shell wildcards.
+ * collectdmon: The new `collectdmon' binary detects when collectd
+ terminates and automatically restarts it again.

+ disable the translation from device names to major-minor-numbers.
+ * logfile plugin: Handling of notifications has been added.
+ * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
+ domain name lookups in this plugin.
+ * perl plugin: Many internal changes added support for handling multiple
+ threads making the plugin reasonably usable inside collectd. The API has
+ been extended to support notifications and export global variables to
+ Perl plugins; callbacks now have to be identified by name rather than a
+ pointer to a subroutine. The plugin is no longer experimental.
+ * uuid plugin: The new UUID plugin sets the hostname to an unique
+ identifier for this host. This is meant for setups where each client
+ may migrate to another physical host, possibly going through one or
+ more name changes in the process. Thanks to Richard Jones from
+ Red Hat's Emerging Technology group for this plugin.
+ * libvirt: The new libvirt plugin uses the `libvirt' library to query
+ CPU, disk and network statistics about guest systems on the same
+ physical server. Thanks to Richard Jones from Red Hat's Emerging
+ Technology group for this plugin.
+
+2008-04-22, Version 4.2.7
+ * build system: Improved detection of several libraries, especially if
+ they are in non-standard paths.
+ * build system: Portability fixes: Automatically define "_REENTRANT"
+ if the libc expects it.
+ * collectd: Error and warning messages have been improved.
+ * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
+ using them.
+ * apache plugin: Allocate new memory when reading a webpage instead of
+ using a buffer of static size.

+ * unixsock plugin: Fix mixed input and output operation on streams.
+ * wireless plugin: Fix reading noise value.
+
+2008-03-04, Version 4.2.5
+ * apache plugin: Improved initialization and error messages.
+ * exec plugin: Set supplementary group IDs.
+ * network plugin:
+ + Create separate threads for reading from the socket and parsing
+ and dispatching incoming packets. Versions prior to this may have
+ problems in high-load situations, where the socket receive buffers
+ overflows, resulting in gaps in the data.
+ + Use `memcpy' when constructing/parsing a package to avoid
+ alignment problems on weird architectures, such as Sparc.
+ + Translate doubles to/from the x86 byte representation to ensure
+ cross-platform compatibility.
+ * ping plugin: Correct the handling of the `TTL' setting.
+ * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
+ * swap plugin: Reapply a patch for Solaris.
+ * tcpconns plugin: Portability improvements.
+
+2008-01-21, Version 4.2.4
+ * unixsock plugin: A bug in the unixsock plugin caused it not to set
+ the permission on the socket as documented in the manpage. Thanks to
+ Evgeny Chukreev for fixing this issue.
+ * collectd: The documentation has been improved.
+
+2007-12-28, Version 4.2.3
+ * sensors plugin: Updated the plugin to build and work with version 3
+ of the libsensors library.
+
+2007-12-15, Version 4.2.2
+ * nginx plugin: Incorrect comparison of strings lead to a segfault
+ when using the plugin. Thanks to Saulius Grigaliunas for fixing
+ this.
+ * logfile plugin: The config option `Timestamp' was handled
+ incorrectly and basically always active. Thanks to Luke Heberling
+ for fixing this.
+
+2007-11-08, Version 4.2.1
+ * tcpconns plugin: Don't complain about a missing file if IPv6 is not
+ enabled on the host.
+ * snmp plugin: Fix a memory leak.
+
+2007-10-27, Version 4.2.0
+ * collectd: The new config option `Include' lets you include other
+ configfiles and thus split up your config into smaller parts. This
+ may be especially interesting for the snmp plugin to keep the data
+ definitions separate from the host definitions.
+ * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
+ (number of connections, octets and packets for each service and
+ destination). Thanks to Sebastian Harl for this plugin.
+ * memcached plugin: The new `memcached' plugin connects to a memcached
+ daemon process and collects statistics of this distributed caching
+ system. Thanks to Antony Dovgal for contributing this plugin.
+ * nginx plugin: The new `nginx' plugin reads the status page of an
+ nginx daemon and saves the handled connections and requests.
+ * perl plugin: Many changes, including the added `EnableDebugger'
+ config option which lets you debug your Perl plugins more easily.
+ * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
+ be more thread-safe otherwise by locking calls to the library.
+ * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
+ correct the values returned by SNMP-agents. If a <data> block is
+ defined as `table' the instance is now optional. The sequence number
+ is used as the type-instance in this case. The new `InstancePrefix'
+ option allows to add arbitrary prefixes to the type-instance.
+ * tcpconns plugin: The new `tcpconns' plugin collects the number of
+ certain TCP connections and what state they're in. This can be used
+ to see how many connections your FTP server has to handle or how
+ many outgoing connections your mailserver has open.
+
+2008-01-11, Version 4.1.6
+ * unixsock plugin: A bug in the unixsock plugin caused it not to set
+ the permission on the socket as documented in the manpage. Thanks to
+ Evgeny Chukreev for fixing this issue.
+ * collectd: The documentation has been improved.
+
+2007-12-27, Version 4.1.5
+ * rrdtool plugin: Fix a memory leak that only occurred in very-low-
+ memory situations.
+ * sensors plugin: Updated the plugin to build and work with version 3
+ of the libsensors library.
+
+2007-11-08, Version 4.1.4

+ a deadlock or delay when shutting down the daemon.
+ * snmp plugin: Fix a memory leak.
+
+2007-10-24, Version 4.1.3
+ * collectd: A build issue under Solaris has been resolved by renaming
+ data types.

+ * apcups plugin: Fix reporting of the `load percent' data.
+ * wireless plugin: Correct the handling of cards returning signal and
+ noise quality as percentage.
+ * perl plugin: Fix a possible buffer overflow in get_module_name().
+ * build system: Further improve the detection of libraries.
+ * netlink plugin: Build issues under some older versions of the Linux
+ includes (i. e. Debian Sarge) have been fixed.
+ * snmp plugin: Fix a potential segfault when a host times out. Add
+ support for the `timeticks' type.
+
+2007-09-12, Version 4.1.1
+ * Build system: The detection of `libnetlink' has been improved.
+ * collectd: The documentation has been fixed in numerous places.
+ * exec plugin: Setting the group under which to run a program has been
+ fixed.
+ * collectd: The `sstrerror' function was improved to work correctly
+ with the broken GNU version of `strerror_r'.
+ * collectd: Write an error message to STDERR when loading of a plugin
+ fails.
+ * apcups plugin: Fix the `types' used to submit the values: They still
+ has an `apcups_' prefix which doesn't work anymore.
+ * rrdtool plugin: Create new RRD-files with the `begin' time set to
+ whatever the client thinks is `now'..
+
+2007-09-01, Version 4.1.0
+ * Build system: The build system has been changed to automatically
+ disable all plugins, which are missing dependencies. The dependency
+ checking has been removed from the plugins themselves to remove
+ redundancy.
+ * Flexible interval: The interval of collected data is now sent along
+ with the data itself over the network, so that the interval-settings
+ of server and clients no longer needs to match.
+ * netlink plugin: The new `netlink' plugin connects to the Linux
+ kernel using a netlink socket and uses it to query information about
+ interfaces, qdiscs and classes.
+ * rrdtool plugin: The cache is now dumped to disk in an extra thread
+ to not block data collection.
+ * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
+ network devices, such as switches, routers, thermometers, rack
+ monitoring servers, etc. The collectd-snmp(5) manpage documents this
+ plugin.
+ * unixsock plugin: Added the `LISTVAL' command.
+ * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
+ of music played with xmms.
+
+2007-09-28, Version 4.0.9
+ * apcups plugin: Fix reporting of the `load percent' data.
+ * wireless plugin: Correct the handling of cards returning signal and
+ noise quality as percentage.
+ * perl plugin: Fix a possible buffer overflow in get_module_name().
+
+2007-09-12, Version 4.0.8
+ * collectd: The `sstrerror' function was improved to work correctly
+ with the broken GNU version of `strerror_r'.
+ * collectd: Write an error message to STDERR when loading of a plugin
+ fails.
+ * apcups plugin: Fix the `types' used to submit the values: They still
+ has an `apcups_' prefix which doesn't work anymore.
+ * rrdtool plugin: Create new RRD-files with the `begin' time set to
+ whatever the client thinks is `now'..
+
+2007-08-26, Version 4.0.7
+ * documentation: Some typos have been fixed and some information has
+ been improved.
+ * build system: Many fixes for detecting libraries in unusual places,
+ such as on RedHat systems. The affected libraries are `libcurl',
+ `libmysql', and `libupsclient'.
+ * network plugin: Allow the `Port' option to be specified as a number
+ (i. e. without quotes).
+ * nut plugin: A fix allows linking the nut plugin against
+ libupsclient, version >= 2.2.0.
+ * processes plugin: Fix a potential segmentation fault.
+
+2007-07-30, Version 4.0.6
+ * sensors plugin: Fix the ignorelist functionality: Only the `type
+ instance' was used to match against the list, but the documentation
+ told otherwise. This release fixes the code, so it complies with the
+ documentation.
+ * syslog plugin: Call `openlog' right when the plugin is loaded, so
+ configuration messages will end up in the logging facility.
+ * conrtib/fedora: The contributed specfile for Fedora has been
+ updated.
+
+2007-07-05, Version 4.0.5
+ * Portability: More fixes for OpenBSD have been included.
+
+2007-06-24, Version 4.0.4

+2007-06-19, Version 4.0.3
+ * cpu plugin: Fix the Darwin / Mac OS X code.
+ * ping plugin: Use the return value of `getpid', not its address.
+ * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
+ initialized correctly.
+ * configure: Added `--with-nan-emulation' to aid cross compilation.
+
+2007-06-12, Version 4.0.2
+ * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
+ they're given in numerically form.
+
+2007-06-07, Version 4.0.1
+ * iptables plugin: A bug in the configuration routine has been fixed.
+ Setting a comment in the configfile will no longer cause a
+ segmentation fault.
+
+2007-06-03, Version 4.0.0
+ * collectd: The plugin-infrastructure has been changed to allow for
+ more types of plugins, namely `write' and `log' plugins.
+ * collectd: The read-function has been changed to read many plugins in
+ parallel, using threads. Thus, plugins generally need to use
+ thread-safe functions from now on.
+ * collectd: The '-t' command line options allows to perform syntax tests
+ of the configuration file and exit immediately.
+ * csv plugin: The new `csv' plugin handles output to `comma separated
+ values'-files.
+ * rrdtool plugin: The new `rrdtool' plugin handles output to
+ RRD-files. Data can be cached to combine multiple updates into one
+ write to increase IO-performance.
+ * network plugin: The new `network' plugin handles IO via the network.
+ It implements a different, much more extensible protocol which can
+ combine many values in one packet, decreasing the number of UDP-
+ packets being sent. It can read from and send to the network and
+ with the appropriate configuration even forward packets to other
+ networks.
+ * unixsock plugin: The new `unixsock' plugin provides an interface to
+ communicate with the daemon while it is running. Right now the
+ commands `GETVAL' and `PUTVAL' are implemented, but more are to
+ come.
+ * perl plugin: The new `perl' plugin allows you to write extensions
+ for collectd in the scripting-language Perl.
+ * logfile plugin: The new `logfile' plugin writes logmessages to files
+ or STDOUT or STDERR.
+ * syslog plugin: The new `syslog' plugin sends logmessages to the
+ system's syslog daemon.
+ * entropy plugin: The new `entropy' plugin collects the amount of
+ entropy currently being available to the system.
+ * exec plugin: The new `exec' plugin forks child processes and reads
+ back values provided by the forked processes.
+ * iptables plugin: The new `iptables' plugin reads counters from
+ iptables rules. Thanks to Sjoerd van der Berg for contributing this
+ plugin.
+ * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
+ to Peter Holik for contributing this plugin.
+ * nut plugin: The new `nut' plugin connects the upsd of the `network
+ ups tools' and reads information about the connected UPS.
+ * apache plugin: Support for lighttpd's `BusyServers' (aka.
+ connections) field was added by Florent Monbillard.
+ * collectd-nagios: The new `collectd-nagios' binary queries values
+ from collectd, parses them and exits according to Nagios-standards.
+ * manpages: The manpages have been improved a lot.
+
+2007-09-28, Version 3.11.7
+ * wireless plugin: Correct the handling of cards returning signal and

+ * processes plugin: Fix a potential segmentation fault.
+
+2007-05-29, Version 3.11.5
+ * configure: Added `AC_SYS_LARGEFILE' for LFS.
+ * ntpd plugin: Fix a potential buffer overflow.
+ * processes plugin: Fix a bug when run under Linux 2.4. All processes
+ were accounted as `zombies'.
+
+2007-04-10, Version 3.11.4
+ * dns plugin: Change the order of includes to make the plugin compile
+ under FreeBSD.
+
+2007-03-30, Version 3.11.3
+ * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
+ of the unused `COLLECT_KSTAT'.
+
+2007-02-11, Version 3.11.2
+ * plugin: Catch NULL-pointer and try to fix them. Otherwise the
+ NULL-pointer may have been passed to `printf' which causes a
+ segfault with some libcs.
+
+2007-02-10, Version 3.11.1
+ * df plugin: Some wrong defines have been fixed so the plugin works
+ under Solaris again.
+ * dns plugin: The usage of a struct has been fixed to work with
+ non-GNU libcs.
+ * processes plugin: Some missing defines have been added so the plugin
+ compiles cleanly under FreeBSD and presumably other UNIXes.
+
+2006-12-22, Version 3.11.0
+ * collectd: The new command line option `-P' makes it easier for
+ distributors to change the location of PID-files.
+ * collectd: The daemon shuts down faster now which makes it easier to
+ write init.d-scripts for it.
+ * apache plugin: Increase the buffersize to 16k, because the 4k buffer
+ caused problems every now and then.
+ * df plugin: New config options allow to ignore certain mountpoints,
+ filesystem types or devices.
+ * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
+ and interprets it. It collects traffic as well as qtype, opcode and
+ rcode counts.
+ * email plugin: Sebastian Harl has contributed this plugin which
+ counts received mails in categories (e. g. ham, spam, virus), spam
+ score (as given by SpamAssassin) and check types.
+ * mbmon plugin: Flavio Stanchina has contributed this plugin which
+ uses `mbmon' to gather information from sensors on the motherboard.
+ * processes plugin: Collect detailed statistics for configured
+ processes, that's process and thread count, CPU usage, resident
+ segment size and pagefaults.
+ * multimeter plugin: Peter Holik contributed a new plugin which
+ queries multimeters.
+ * sensors plugin: Lubos Stanek has put much effort into improving this
+ plugin, including `extended naming', collection of voltage values
+ and the possibility to ignore certain values.
+
+2006-12-21, Version 3.10.4
+ * Max Kellermann has identified a bug in the server routine: When
+ opening a socket fails the daemon will (re)try opening the socket in
+ an endless loop, ultimately leading to a `EMFILE' error.
+
+2006-11-04, Version 3.10.3
+ * Lubos Stanek has identified a bug in the ntpd-plugin: When the
+ ntpd's reply was sent in more than one packet, the buffer size was
+ calculated incorrectly, resulting in the reading of uninitialized or
+ freed memory.
+
+2006-11-01, Version 3.10.2
+ * The sample config file has been improved.
+ * Errors in the manpages have been corrected.
+ * The ping-plugin now adds hosts during initialization, not during
+ startup. This speeds up startup when no network connectivity is
+ available. Also, the hosts are being added later when the network is
+ available.
+ * Improved BSD-support for the df-plugin.
+ * Fixed syntax errors in the swap-plugin for Mac OS X.
+ * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
+ plugin.
+ * Don't disable the mysql-plugin if connecting to the database fails
+ during initialization. Instead, try again in increasing intervals.
+
+2006-07-19, Version 3.10.1
+ * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
+ the apcups cannot be reached, unconnected sockets will pile up and
+ eventually lead to `Too many open files' errors.
+
+2006-07-09, Version 3.10.0
+ * The `disk' plugin has been ported to Darwin.
+ * The `battery' plugin should work on many Apple computers now.
+ * The `traffic' plugin can now ignore certain interfaces. Also,
+ statistics for sent/received packets and errors have been added.
+ * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
+ to Anthony Gialluca for contributing this plugin and providing me
+ with a test environment :)
+ * A plugin for monitoring an NTP instance and the local clock drift
+ has been added.
+
+2006-06-25, Version 3.9.4
+ * The Solaris code in the `swap' plugin has been changed to reflect
+ the numbers returned by `swap -s'. Thanks to Christophe Kalt for
+ working this out.
+ * The debugging system has been fixed to work with the Sun libc.
+ * When built without librrd the variable `operating_mode' could be
+ uninitialized. Thanks to David Elliot for reporting the bug.
+
+2006-06-01, Version 3.9.3
+ * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
+ operating systems also profit from the changes, but I wasn't able to
+ check that.
+ * Changed the build system to find the netinet-includes under FreeBSD
+ and therefore successfully build the `liboping' library there.
+
+2006-05-09, Version 3.9.2
+ * Applied a patch to the `liboping' library. Due to a bug in the
+ sequence checking the `ping' plugin stopped working after
+ approximately 7.6 days.
+
+2006-05-09, Version 3.8.5
+ * Applied a patch to the `liboping' library. Due to a bug in the
+ sequence checking the `ping' plugin stopped working after
+ approximately 7.6 days.
+
+2006-04-21, Version 3.9.1
+ * Build issues with Solaris and possible other architectures have been
+ resolved.
+ * Problems when building the `apache'-plugin without `libcurl' have
+ been resolved.
+ * A bug in the `ping' plugin has been fixed. Sorry folks.
+
+2006-04-02, Version 3.9.0
+ * A plugin to monitor the Apache webserver has been added.
+ <http://httpd.apache.org/>
+ * A plugin to collect statistics about virtual servers using VServer.
+ <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
+ this plugin :)
+ * A plugin for wireless LAN cards has been added. It monitors signal
+ strength, link quality and noise ratio..
+ * A plugin for Apple hardware sensors has been added.
+ * An option to compile collectd with different `step' and `heartbeat'
+ settings has been added. The size of RRAs is no longer static but
+ calculated based on the settings for `step' and `width'.
+ * The `ping' plugin can now be configured to use a certain TTL.
+ * A plugin to monitor the hardware sensors of Apple computers has been
+ added.
+ * The plugins `cpu', `memory', `processes' and `traffic' have been
+ ported to Mach/Darwin (Mac OS X).
+ * The `log mode' has been contributed by Christophe Kalt. It writes
+ the data into text files rather than RRD files.
+
+2006-04-09, Version 3.8.4
+ * Applied patch by Vincent Stehlé which improves the disk-name
+ resolution in the `hddtemp' plugin for Linux systems.
+
+2006-04-02, Version 3.8.3
+ * Applied a patch by James Byers: The MySQL plugin was not working
+ with MySQL 5.0.2 or later.
+
+2006-03-14, Version 3.8.2
+ * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
+ the GNU libc, because it points to `/etc/fstab' rather than
+ `/etc/mtab'.
+
+2006-03-13, Version 3.8.1
+ * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
+ * Fixes in the debian `postinst' and `init.d' scripts.
+
+2006-03-09, Version 3.8.0
+ * The `ping' plugin no longer uses `libping' but a self written
+ library named `liboping'. With this library it's possible to ping
+ multiple IPv4 and IPv6 addresses and hostnames - in parallel.
+
+2006-02-18, Version 3.7.2
+ * A simple bug in the `battery' plugin has been fixed. It should now
+ work with ACPI based batteries as well. Thanks to Sebastian for
+ fixing this.
+ * Fixing a bug that prevented collectd to be built without librrd.
+ Thanks to Werner Heuser for reporting it.
+
+2006-02-04, Version 3.7.1
+ * The new network code has been improved to build with older versions
+ of glibc.
+ * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
+ to Tommie Gannert for this patch.
+
+2006-01-30, Version 3.7.0
+ * The `battery' plugin has been added. It collects information about
+ laptop batteries..
+ * The MySQL plugin has been improved: It now writes two more RRD
+ files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
+ * The `cpufreq' plugin now reads another file since the file it did
+ read so far causes much overhead in the kernel. Also, you need root
+ to read the old file, but not to read the new one.
+ * The `hddtemp' plugin can now be configured to connect to another
+ address and/or port than localhost.
+ * The `df' plugin now prefers `statvfs' over `statfs'.
+ * The network code has been rewritten. collectd now supports unicast
+ and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
+ be set in the configfile.
+
+2006-01-24, Version 3.6.2
+ * Due to a bug in the configfile handling collectd wouldn't start in
+ client mode. This released fixes this.
+
+2006-01-20, Version 3.6.1
+ * Due to a bug in `configure.in' all modules and the binary were
+ linked against `libmysqlclient'. This issue is solved by this
+ release.
+
+2006-01-17, Version 3.6.0
+ * A config file has been added. This allows for loading only specific
+ plugins.
+ * A `df' plugin has been added.
+ * A `mysql' plugin has been added.
+ * The `ping' plugin doesn't entirely give up hope when a socket error
+ occurred, but will back of and increase the intervals between tries.
+
+2006-01-21, Version 3.5.2
+ * Fixed yet another bug in the signal handling.. Stupid typo..
+ * Improved the ping plugin to not give up on socket errors (backport
+ from 3.6.0).
+
+2005-12-18, Version 3.5.1
+ * The PID-file is now deleted correctly when shutting down the daemon.
+ * SIGINT and SIGTERM are now handled correctly.
+
+2005-12-16, Version 3.5.0 (Revision 326)
+ * A bug in the `load' module under Solaris has been fixed.
+ * The `users' module has been contributed by Sebastian Harl. It counts
+ currently logged in users.
+ * The CPU module now works under FreeBSD without the use of
+ `libstatgrab', however SMP support is missing.
+ * The default directories for the RRD files and the PID file now
+ depend on the compile time setting of `localstatedir'.
+
+2005-11-15, Version 3.4.0 (Revision 236)
+ * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
+ from gentoo's bugzilla for writing the patch.
+ * The build dependency for librrd has been removed. Binaries built
+ without librrd are client-only and will multicast their value as
+ with the `-c' argument.
+ * A patch by Peter Holik adds a module for monitoring CPU frequencies.
+ * The newly introduced `-f' switch prevents daemon initialization
+ (forking, closing standard filehandles, etc.) Thanks to Alvaro
+ Barcellos for this patch.
+
+2005-11-04, Version 3.3.0 (Revision 216)
+ * New modules have been added:
+ - `serial', for monitoring traffic on the serial interfaces
+ - `nfs', for graphing NFS procedure calls
+ - `tape', traffic from/to tape devices
+ * The memory.rrd now accepts more than 4Gig of memory.
+
+2005-10-26, Version 3.2.0 (Revision 200)
+ * Support for graphing the processes has been added (thanks to Lyonel
+ Vincent)
+ * If reading from hddtemp fails collectd will increase the time
+ between polls up to one day.
+ * The init.d files have been improved.
+ * Problems with the spec file have been fixed.
+
+2005-10-16, Version 3.1.0 (Revision 194)
+ * Added the `setsid' syscall to the startup code.
+ * Support for hddtemp has been added (thanks to Vincent Stehlé)
+
+2005-09-30, Version 3.0.0 (Revision 184)
+ * The ability to send/receive data to/from the network (think
+ multicast) has been added.
+ * Modules have been split up into shared libraries can be loaded at
+ runtime. The biggest advantage is that the core program doesn't need
+ to be linked against an external library.
+ * A patch by George Kargiotakis has been applied: It fixes the sensors
+ behaviour then more than one sensor is being queried.
+
+2005-09-16, Version 2.1.0 (Revision 172)
+ * A module for swap statistics has been added.
+
+2005-09-09, Version 2.0.0 (Revision 135)
+ * Filenames can no longer be configured at program startup. The only
+ options as of this version are the directory and ping hosts.
+ * CPU statistics now include Wait-IO. If provided under Linux IRQ and
+ Soft-IRQ statistics are added to `System'.
+ * Diskstats now collect read and write bytes, not sectors.
+ * Ping statistics can now be collected for more than one host. There
+ is no default any more: If no host is given no host will be pinged.
+ * A self-written patch for libping has been applied so it builds
+ cleanly.
+
+2005-09-01, Version 1.8.1 (Revision 123)
+ * Much improved configure-script: libraries and features may now be
+ disabled.
+ * More detailed warnings/error messages when RRD update fails.
+
+2005-08-29, Version 1.8.0:
+ * Support for collecting disk statistics under Solaris.
+
+2005-08-25, Version 1.7.0:
+ * Support for libstatgrab[1] for load, memory usage and network
+ traffic. CPU- and disk-usage are not (yet) supported, since
+ libstatgrab returns insufficient information. I will contact the
+ authors.
+ * Improved the CPU-initialization code for Solaris. Apparently CPUs
+ aren't necessarily counted linear which is now handled correctly.
+ [1]: http://www.i-scream.org/libstatgrab/
+
+2005-08-21, Version 1.6.0:
+ * Basic support for Solaris: System load and cpu-usage can be
+ collected under Solaris, too. Other stats will follow later.
+ * Many fixes in the autoconf-script
+ * Collection/Museum scripts have been added under contrib/museum
+ * collectd may now be started in unprivileged mode, though ping
+ statistics will not work.
+
+2005-07-17, Version 1.5.1:
+ * Diskstats-RRDs now use major/minor for naming. Some systems have
+ weird strings as disk-names..
+
+2005-07-17, Version 1.5:
+ * A new module, diskstats, has been added. It collects information
+ about the disks and partitions.
+
+2005-07-11, Version 1.4.2:
+ * The meminfo module has been changed to work with more platforms
+ and/or kernel versions.
+
+2005-07-10, Version 1.4.1: Correct traffic stats
+ * The traffic rrd-file is now created with DS-type `COUNTER' which I
+ forgot to correct when I changed that module.
+
+2005-07-09, Version 1.4: More traffic stats
+ * Traffic is now collected for all interfaces that can be found
+ * Temperature-statistics are read from lm-sensors if available
+
+2005-07-08, Version 1.3: CPU stats
+ * Collecting CPU statistics now
+
+2005-07-12, Version 1.2: Using syslog
+ * collectd is now using the syslog facility to report errors, warnings
+ and the like..
+ * The default directory is now /var/db/collectd
+
+2005-07-10, Version 1.1: Minor changes
+ * Nothing really useful to say ;)
+
+2005-07-09, Version 1.0: Initial Version
+ * The following modules are provided:
+ * Load average
+ * Ping time
+ * Traffic
+ * Memory info
