        * 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 :)

+         has been added.

+         and therefore successfully build the `liboping' library there.
