0.13.0

This release updates to Rustls 0.23.4 and continues to use *ring* as the only cryptographic provider.

Added

• A new rustls_accepted_alert type is added. Calling rustls_accepted_alert_bytes on this type produces TLS data to write in the case where a server acceptor encountered an error accepting a client. The returned TLS data should be written to the connection before freeing the rustls_accepted_alert by calling rustls_accepted_alert_write_tls with a rustls_write_callback implementation.

Changed

• The rustls_acceptor_accept and rustls_accepted_into_connection API functions now require an extra rustls_accepted_alert out parameter. This parameter will only be set when an error occurs accepting a client connection and can be used to write any generated alerts to the connection to signal the accept error to the peer.

• The experimental cargo-c build support has been updated to use a vendored header file. This avoids the need for nightly rust or cbindgen when using this build method.
