The WP AnythingSlider 3.0 has been released. This is a MAJOR update and you should proceed with caution when updating.
The plugin has been completely re-written and will NOT work as a direct upgrade from the previous plugin. It was suggested initially by CodeCanyon that because the plugin has been revamped so much that it be submitted as a new plugin altogether, but I want to provide the update to all current customers, so it has been released as an update rather than a new plugin.
