This version includes some nice new features and fixes a lot of small issues. It also adds a new tutorial about WYSIWYG editors and the new CONTRIBUTING guide.
The most important feature is the introduction of EntityTypeConfigurator, which allows to define custom configuration options for any form field. This change doesn't affect you in any way while creating backends, but it provides us a great flexibility to tweak form types, specially those provided by third-party bundles.
The first example of EntityTypeConfigurator in action is the CKEditor provided by IvoryCKEditorBundle. When you use that editor in an EasyAdmin backend, its default configuration is better than when you use it in your own Symfony applications. Our intention is to provide great default configurations for some popular third-party bundles in order to improve their integration with EasyAdmin.
