With TYPO3 8.7 I get error messages like Medienreaktor\FormDoubleoptin\Controller\FormDoubleOptInController is not found. They disappeared after renaming the class path from FormDoubleOptIn to FormDoubleoptin in all files. The naming conventions in Extbase are IMHO that the extension directory is changed to CamelCase: form_doubleoptin -> FormDoubleoptin.
