v0.8.1

Fixed

• Adapters: the Express/Node and fetch-based adapters read at most 1 MiB of a request body and answer 413 for larger ones, instead of buffering bodies of any size. Change the limit with maxBodySize on toExpressHandler, toNodeHandler or toFetchHandler.
• Akbank: completeThreeDSPayment() confirms the 3D Secure result with an order history query (txnCode 1010) and rejects a callback that does not match Akbank's record for the order as INVALID_HASH. A query that gets no response returns pending with NETWORK_ERROR.
• Handler: only provider callbacks accept form bodies. Other actions answer 415 for application/x-www-form-urlencoded, multipart/form-data and text/plain, which a cross-site HTML form can send with the user's cookies and without a CORS preflight.
• HttpError.config no longer keeps the request body and headers. The error is passed to the logger, and the body carried card data and Parampos credentials, the headers the iyzico authorization.
• iyzico: a failed completeThreeDSPayment() result no longer carries paymentId or conversationId taken from the callback request or echoed by iyzico's error response. They are set only for a successful payment, from iyzico's response.
