How wp_ajax_nopriv since WordPress 3.1

I have a question.
When I was on WordPress 3.0, my ajax function worked. It return good things when I’m log in and log out.

add_action(‘wp_ajax_my_action’, ‘my_action_callback’);
add_action(‘wp_ajax_nopriv_my_action’, ‘my_action_callback’);

Now since WordPress 3.1, I saw wp_ajax_nopriv_my_action is deprecated. So, for a visitor, my ajax function doesn’t work.

What is the alternative ajax function for WordPress 3.1 ? Please

Site you referred to is likely being updated in automated fashion. The reason it wrongfully claims that action is deprecated is because:

• you are looking at page for wp_ajax_nopriv_{$_POST[action]}
• while in recent WP versions actual code is wp_ajax_nopriv_{$_REQUEST[action]} (also documented on that site).

So action is not deprecated, its functionality is not changed (only the way variable is accessed) and it is fully functional in current WP version.
