Since the introduction of WordPress 3.2, the ‘Search Engines Blocked’ notification has been moved to the ‘Right Now’ Box. In a development environment it is preferred to have this notification in clear view, so you cannot overlook it when you have moved the website to a production environment. SO, this plugin places the ‘Search Engines Blocked’ message in the WordPress Toolbar.

See the WordPress.org plugin page for the changelog.
