Free version 3.12 is available for download. It is security and vulnerability fix release generally:

• Critical update: persistent cross-site scripting vulnerability is fixed.
• WordPress built-in constants, like WP_PLUGIN_URL are not used in order to provide compatibility with sites which use SSL. plugin_dir_url(), plugin_dir_path() functions are used to define paths to the plugin’s files instead.
• “Greetings” section is removed from the plugin’s main page. All that content is still available at (plugin page)[http://shinephp.com/user-role-editor-wordpress-plugin].

Yes, Hello Word! This is the 1st my post here, at role-editor.com, thus, as any 1st example on a new programming language, traditionally, 1st greetings at new blog from a programmer to public would be the same – Hello World!
This site is dedicated to User Role Editor WordPress plugin and this plugin users support.
