+2012-01-21, Version 5.0.2
+ * curl_xml plugin: Fix handling of file:// and other URLs (which don't

+ * df plugin: Fix handling of negative "available" counts. This can
+ occur with some file systems, for example UFS. Thanks to Toni Ylenius
+ for his patch.

+ their patches.
+ * memory plugin: Account kernel and unused memory under Solaris. Thanks
+ to Fabien Wernli for his patch.
+ * network plugin: A bug in the interaction between the Network plugin

+ have ended up using the modified name rather than the original name.
+ Thanks to Sebastian Harl for identifying the problem.
+ * oracle plugin: A memory leak has been fixed in the parameter handling.
