+2008-03-29, Version 4.3.2
+ * collectd: Fix configuration of the `FailureMax', `WarningMax', and
+ `Persist' threshold options.
+ * collectd: Fix handling of missing values in the global value cache.
+ * collectd: Improved error messages when parsing the configuration.
+ * sensors plugin: Fix temperature collection with libsensors4.
+ * unixsock plugin: Fix mixed input and output operation on streams.
+ * wireless plugin: Fix reading noise value.
+
+2008-03-05, Version 4.3.1
+ * exec plugin: Set supplementary group IDs.
+ * network plugin:
+ + 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.
+ * swap plugin: Reapply a patch for Solaris.
+ * 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.
+ * csv plugin: The CSV plugin is now able to store counter values as a
+ rate, using the `StoreRates' configuration option.
+ * exec plugin: Handling of notifications has been added and the
+ ability to pass arguments to the executed programs has been added.
+ * hddtemp plugin: The new `TranslateDevicename' option lets you
+ 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.
+
+2008-03-29, Version 4.2.6
+ * collectd: Improved error messages when parsing the configuration.
+ * sensors plugin: Fix temperature collection with libsensors4.
+ * 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
+ * Build system: Improve detection of the rrd library, especially if
+ it's in a non-standard location.
+ * Build system: A bug when parsing the argument for
+ `--with-libnetsnmp' has been fixed.
+ * collectd: Implement `strerror_r' if the libc doesn't provide it.
+ * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
+ 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.
+ * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
+ be more thread-safe otherwise by locking calls to the library.
+
+2007-09-28, Version 4.1.2
+ * 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
+ * cpu plugin: Fixed the Solaris code.
+ * dns plugin: Fixed a build issue for OpenBSD.
+ * interface plugin: Fixed the Solaris code.
+ * load plugin: Fixed the alternative `/proc' Linux code.
+ * memory plugin: Fixed the Solaris code.
+ * oconfig: Don't require `-lfl' anymore.
+
+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
+ noise quality as percentage.
+
+2007-08-31, Version 3.11.6
+ * 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
