* The `battery' plugin should work on many Apple computers now.
* The `traffic' plugin can now ignore certain interfaces. Also,
statistics for sent/received packets and errors have been added.
+ * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
+ to Anthony Gialluca for contributing this plugin and providing me
+ with a test environment :)
+ * A plugin for moniroting an NTP instance and the local clock drift
+ has been added.
+
+2006-06-01, Version 3.9.3
+ * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
+ operating systems also profit from the changes, but I wasn't able to
+ check that.
+ * Changed the build system to find the netinet-includes under FreeBSD
+ and therefore successfully build the `liboping' library there.
2006-05-09, Version 3.9.2
* Applied a patch to the `liboping' library. Due to a bug in the
