+
+## Introduction
+
+The v2 of this bundle is based upon the Friendly Captcha v2 version: https://developer.friendlycaptcha.com/docs/v2
+
+#### Breaking changes
+
+* Removed the form options: `lang`, `callback`, `puzzle-endpoint` and `lang` .
+
+#### Requirements
+
+* To activate the v2 a new api key is necessary: https://developer.friendlycaptcha.com/docs/v2/guides/upgrading-from-v1/backend-integration#3-replace-the-secret-field
+* For a v2 migration front guide: https://developer.friendlycaptcha.com/docs/v2/guides/upgrading-from-v1/script
