- yyyy-mm-dd, Version 4.0.9
 +yyyy-mm-dd, Version 4.1.2
 +      * apcups plugin: Fix reporting of the `load percent' data.
 +      * netlink plugin: Build issues under some older versions of the Linux
 +        includes (i. e. Debian Sarge) have been fixed.
 +
 +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
