+Version 6 of the FOSElasticaBundle is compatible with Elasticsearch 7. It requires Symfony 5.4 or greater. When using
 Symfony Flex there is also a [recipe to ease the setup](https://github.com/symfony/recipes-contrib/tree/master/friendsofsymfony/elastica-bundle/5.0).
 Earlier versions of the FOSElasticaBundle are not maintained anymore and only work with older versions of the dependencies.
 The following table shows the compatibilities of different versions of the bundle.
