+
+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)'.

+ * 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

+
+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

+
+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
