+Symfony Polyfill / Php70
+========================
+
+This component provides features unavailable in releases prior to PHP 7.0:
+
+- [`intdiv`](http://php.net/intdiv)
+- [`preg_replace_callback_array`](http://php.net/preg_replace_callback_array)
+- [`error_clear_last`](http://php.net/error_clear_last)
+- `random_bytes` and `random_int` (from [paragonie/random_compat](https://github.com/paragonie/random_compat))
+- [`*Error` throwable classes](http://php.net/Error)
+- [`PHP_INT_MIN`](http://php.net/manual/en/reserved.constants.php#constant.php-int-min)
+- `SessionUpdateTimestampHandlerInterface`
+
+More information can be found in the
+[main Polyfill README](https://github.com/symfony/polyfill/blob/master/README.md).
+
+Compatibility notes
+===================
+
+To write portable code between PHP5 and PHP7, some care must be taken:
+- `\*Error` exceptions must be caught before `\Exception`;
+- after calling `error_clear_last()`, the result of `$e = error_get_last()` must be
+  verified using `isset($e['message'][0])` instead of `null !== $e`.
