The admin_user_info_links filter is gone in 3.3

Version 3.3 combines the adminadmin (and super admin) headerHeader The header of your site is typically the first thing people will experience. The masthead or header art located across the top of your page is part of the look and feel of your website. It can influence a visitor’s opinion about your content and you/ your organization’s brand. It may also look different on different screen sizes. 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 filterFilter Filters are one of the two types of Hooks They provide a way for functions to modify data of other functions. They are the counterpart to Actions. Unlike Actions, filters are meant to work in an isolated manner, and should never have side effects such as affecting global variables and output.. 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 UIUI User interface continues to be refined.
