 Version 1.02.78 - 
 ===================================
+  Validate passed params to dm_get_status_raid/thin/thin_pool(). 
   Fix 'dmsetup splitname -o' to not fail if used without '-c' switch (1.02.68).
   Add dm_config_write_{node_out/one_node_out} for enhanced config output.
   Add dm_config_value_is_bool to check for boolean value in supported formats.
