 -------------
+* Version **2.0.0** supports now Symfony 4! Symfony 2.x support was dropped. You can also configure now a file extension validation whitelist (PR [#289](https://github.com/1up-lab/OneupUploaderBundle/pull/289))
 * Version **1.5.0** supports now [Flysystem](https://github.com/1up-lab/OneupFlysystemBundle) (Thank you @[lsv](https://github.com/lsv)! PR [#213](https://github.com/1up-lab/OneupUploaderBundle/pull/213)) and is no longer compatible with PHP 5.3 (it's [EOL](http://php.net/eol.php) since August 2014 anyway).
