   I find it annoying when the admin footer tells you that a new Wordpress version is available (for example “Get Version 4.6.1”) but does not tell you what your current version is.
   Here is a patch:

   
   // Improve Admin footer update notice.
   if (!function_exists('smarter_update_footer')){
   	function smarter_update_footer( $msg = '' ) {
   		if ( !current_user_can('update_core') )
   			return sprintf( __( 'Version %s' ), get_bloginfo( 'version', 'display' ) );
   
   		$cur = get_preferred_from_update_core();
   		if ( ! is_object( $cur ) )
   			$cur = new stdClass;
   
   		if ( ! isset( $cur->current ) )
   			$cur->current = '';
   
   		if ( ! isset( $cur->url ) )
   			$cur->url = '';
   
   		if ( ! isset( $cur->response ) )
   			$cur->response = '';
   
   		switch ( $cur->response ) {
   		case 'development' :
   			return sprintf( __( 'You are using a development version (%1$s). Cool! Please <a href="%2$s">stay updated</a>.' ), get_bloginfo( 'version', 'display' ), network_admin_url( 'update-core.php' ) );
   
   		case 'upgrade' :
   			return '<strong>'.sprintf( __( 'Version %s' ), get_bloginfo( 'version', 'display' ) ).' - <a href="' . network_admin_url( 'update-core.php' ) . '">' . sprintf( __( 'Get Version %s' ), $cur->current ) . '</a></strong>';
   
   		case 'latest' :
   		default :
   			return sprintf( __( 'Version %s' ), get_bloginfo( 'version', 'display' ) );
   		}
   	}
   	add_filter( 'update_footer', 'smarter_update_footer', 9999);
   }
