+yyyy-mm-dd, 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.
+       * 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 a special
+         executable type for Nagios plugins has been implemented. Also, the
+         ability to pass arguments to the executed programs has been added.
+       * 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.

        * 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
