Breaking Changes

1. Default value change for CPPHTTPLIB_PAYLOAD_MAX_LENGTH

• Old: std::numeric_limits<size_t>::max() (effectively unlimited)
• New: 100 * 1024 * 1024 (100MB)
• Code that receives payloads larger than 100MB will now fail with ExceedMaxPayloadSize error

2. Introduction of the TLS Abstraction Layer (Abstract TLS API)

• Mbed TLS can now be used by defining CPPHTTPLIB_MBEDTLS_SUPPORT
• Request::ssl (SSL* type) has been removed and replaced with Request::ssl (tls::const_session_t type)
• ClientConnection::ssl has similarly been changed to tls::session_t
• Constructors and methods that directly use OpenSSL types (X509*, EVP_PKEY*, etc.) are now deprecated
