- 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
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.
