+yyyy-mm-dd, Version 4.0.9
+ * apcups plugin: Fix reporting of the `load percent' data.
+
+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.
