Besides an easy-to-use semantic configuration, the
ContentfulBundle integrates with Symfony Web Profiler, allowing you to debug bugs and performance issues on the integration point between your application and Contentful.
The ContentfulBundle requires at least PHP 5.5.9 and Symfony 2.7. PHP 7 and Symfony 3 are supported, too.
Just like the underlying PHP SDK the ContentfulBundle is currently in beta, and its API still might change.
