Implemented support for new payment method Maestro
Support for multiple languages: German, Spanish, English, French
Allow deactivation of the additional data form for direct debit, so that the corresponding intermediate (external) form is used instead (this is useful for cases where this form causes conflicts in the shop). Name of the option: Enable external form service / Externen Formularservice aktivieren. Default is off.
For giropay and eps, removed the Javascript widget and the field for entering the BIC. All transactions will now be initialized without BIC so the external form service is used. Entering the BIC within the plugin is not supported anymore.
Add separate error message if connection to GS server is not possible due to errors in parameter configuration (Merchant-ID, Project-ID, Project-Password).
Paydirekt: Support for digital carts.
Change Direct Debit, VISA/MasterCard and Sofort logos to the new ones.
Allow refunds: In order overview in the shop system, allow the user to initiate a refund for payment types: creditcard, directdebit, maestro, paydirekt.
Allow reservations and captures, where reservation is configurable in backend as default transaction type for credit card, direct debit and paydirekt. If reservation (or auth) is configured, all payments are made with that type and the capture is then made when the order state is changed to shipped.
