The admin_user_info_links filter is gone in 3.3

Version 3.3 combines the admin header and the admin bar into one toolbar in the dashboard.

As the “Howdy” dropdown menu in the admin is now part of the admin bar, we’ve dropped the admin_user_info_links filter. This filter was previously used by plugins to insert links near “Howdy, name | Logout” and eventually as items in the dropdown added in 3.2.

Now what you can do is add links to the account menu, like so:

add_action( 'admin_bar_menu', 'nacin_add_account_menu_item' );
function nacin_add_account_menu_item( $wp_admin_bar ) {
    $wp_admin_bar->add_node( array(
        'id'     => 'secondary-profile-page',
        'parent' => 'user-actions',
        'title'  => 'Personal Settings',
        'href'   => menu_page_url( ... ),
    ) );

This follows us dropping favorite actions (and specifically the favorite_actions filter) in 3.2 as the UI continues to be refined.
