A bug fix has been added to allow deny-spawn as a default flag for regions to work.

Also to note, metrics have now been enabled in the plugin (bStats). This makes no performance difference, and is used by major plugins (WorldEdit, WorldGuard, etc.) to help plugin developers to have a better idea of plugin usage. If you would like to turn off all metrics on your server, you can go to the folder bStats in your plugins folder (note: this turns off metrics for all plugins using it).
