    $response seems to be an object, not an array here.

    I used this hook to be able to display an upgrade notice message just after the new version message, like so:

    function wpdocs_plugin_update_message( $plugin_data, $new_data ) {
    	if ( isset( $plugin_data['update'] ) && $plugin_data['update'] && isset( $new_data->upgrade_notice ) ) {
    			'<div class="update-message"><p><strong>%s</strong>: %s</p></div>',
    			$new_data -> new_version,
    			wpautop( $new_data -> upgrade_notice )
    add_action( 'in_plugin_update_message-my-plugin-name/my-plugin-name.php', 'wpdocs_plugin_update_message', 10, 2 );

    But it seems like upgrade_notice isn’t available anymore. This code is still a good way to warn user for important upgrades. :)
