 +2014-01-26, Version 5.4.1
 +      * amqp plugin: Add support for RabbitMQ 0.4.x to avoid compiler
 +        warnings. Thanks to Sebastian Harl for implementing this.
 +      * apache / network plugins: Improved initialization order hopefully
 +        resolved gcrypt initialization problems.
 +      * aquaero plugin: The type used to submit fan utilization was fixed.
 +        Thanks to Alex Deymo for the patch.
 +      * cgroups plugin: A small memory leak was fixed. Checking the existence
 +        of a mount option without a value was fixed. More permissive parsing
 +        of the cpuacct.stats file fixes support for some versions of Linux.
 +        Thanks to Marc Fournier for bug reports and patches.
 +      * curl plugin: Fix <Match> blocks without an instance. Thanks to
 +        Alexander Golovko for reporting and Sebastian Harl for fixing this.
 +      * curl_json plugin: Potentially invalid memory access has been
 +        sanitized. Thanks to Jim Radford for his patch.
 +      * interface plugin: Fix behavior under FreeBSD 10: Reporting of
 +        per-address statistics caused duplicate updates to the same metric.
 +        Thanks to demon / @trtrmitya for the patch.
 +      * write_graphite plugin: Use TCP to connect to Graphite by default. The
 +        default changed from TCP to UDP between 5.3.1 and 5.4.0, which is a
 +        regression. Thanks to Marc Fournier for fixing this. Reconnect
 +        behavior was improved. Thanks to Michael Hart for his patch.
 +      * zfs_arc plugin: Collect "allocated" and "stolen" on FreeBSD only.
 +
 +2013-08-18, Version 5.4.0
 +      * collectd: The "LoadPlugin" config option no longer attempts to load
 +        plugins twice. If more than one "LoadPlugin" statement or block is
 +        encountered, only the first will have any effect.
 +      * collectd: The "AutoLoadPlugin" option allows to automatically load
 +        plugins for which a configuration is found.
 +      * collectd: The "WriteQueueLimitHigh" and "WriteQueueLimitLow" options
 +        allow collectd to drop values when under stress, to avoid running out
 +        of memory. Thanks to Yves Mettier for his patch.
 +      * amqp plugin: The "GraphiteSeparateInstances" and
 +        "GraphiteAlwaysAppendDS" options have been added. Thanks to Laurent
 +        for the patch.
 +      * aquaero plugin: This new plugin reads various metrics, e.g. fan
 +        speeds and temperatures, from Aquaero 5, a fan and water cooling
 +        control panel. Thanks to Alex Deymo for his patch.
 +      * curl plugin: The "MeasureResponseCode" option has been added. Thanks
 +        to Jan Matějka for his patch.
 +      * curl_json plugin: Support for UNIX domain sockets and array wildcards
 +        has been added. Thanks to Jim Radford for his patch.
 +      * curl_xml plugin: Support for long URLs has been improved.
 +      * cgroups plugin: This new plugin collects CPU accounting information
 +        for processes in a cgroup. Thanks to Michael Stapelberg for his patch.
 +      * df plugin: The "ValuesAbsolute" and "ValuesPercentage" options have
 +        been added. Thanks to Vedran Bartonicek for the patch.
 +      * exec plugin: Do UID / GID lookups before forking. This should prevent
 +        a race condition in the NSS library. Thanks to Ceri Storey for the
 +        patch.
 +      * lvm plugin: This new plugin collects size information from Linux'
 +        Logical Volume Manager (LVM). Thanks to Chad Malfait for his work.
 +      * memcached plugin: Support for increment and decrement counts has been
 +        added. Thanks to Blake Matheny for the patch.
 +      * mic plugin: This new plugin collects CPU and memory usage, power
 +        consumption and temperatures of Intel's Many-Integrated-Core (MIC)
 +        architecture, such as Xeon Phi cards. Thanks to Evan Felix for his
 +        work.
 +      * netlink plugin: This plugin has been converted to use the supported
 +        "libmnl" library. Thanks to Andreas Henriksson for his patch.
 +      * nginx plugin: Collection of accepted and handled connections has been
 +        added. Thanks to Patrick Shan for his patch.
 +      * sigrok plugin: This new plugin collects metrics from sigrok, a signal
 +        processing framework reading various hardware devices, from light
 +        meters to spectrum analyzers. Thanks to Bert Vermeulen for his patch.
 +      * statsd plugin: This new plugin listens to a UDP socket and reads
 +        metrics in the StatsD format.
 +      * varnish plugin: Many additional metrics have been added. Thanks to
 +        Nick Stenning for his patch.
 +      * write_graphite plugin: Support for "UDP" has been added. Thanks to
 +        Javier Maestro for his patch.
 +      * write_riemann plugin: The "TTLFactor" option has been added.
 +      * zfs_arc plugin: Support for FreeBSD has been added. Thanks to Xin Li
