php-symfony-locale 2.8.7+dfsg-1ubuntu1 (amd64 binary) in ubuntu yakkety

 The Symfony Locale Component provides fallback code to handle
 cases when the PHP intl extension is missing. Since version 2.3 of
 Symfony Components it is deprecated and will be removed in Symfony 3.0.
 Additionally it only implements the English locale and thus can not be
 a full replacement of the PHP intl extension.
 .
 Symfony is a PHP framework, a set of tools and a development methodology.
