 I've just released gnutls 3.6.4. This release adds support for the
final TLS 1.3 protocol version, and enables it by default. The more
detailed list of changes follows.

* Version 3.6.4 (released 2018-09-24)

** libgnutls: Added the final (RFC8446) version numbering of the TLS1.3 protocol.

** libgnutls: Corrected regression since 3.6.3 in the callbacks set with
   gnutls_certificate_set_retrieve_function() which could not handle the case where
   no certificates were returned, or the callbacks were set to NULL (see #528).

** libgnutls: gnutls_handshake() on server returns early on handshake when no
   certificate is presented by client and the gnutls_init() flag GNUTLS_ENABLE_EARLY_START
   is specified.

** libgnutls: Added session ticket key rotation on server side with TOTP.
   The key set with gnutls_session_ticket_enable_server() is used as a
   master key to generate time-based keys for tickets. The rotation
   relates to the gnutls_db_set_cache_expiration() period.

** libgnutls: The 'record size limit' extension is added and preferred to the
   'max record size' extension when possible.

** libgnutls: Provide a more flexible PKCS#11 search of trust store certificates.
   This addresses the problem where the CA certificate doesn't have a subject key
   identifier whereas the end certificates have an authority key identifier (#569)

** libgnutls: gnutls_privkey_export_gost_raw2(), gnutls_privkey_import_gost_raw(),
   gnutls_pubkey_export_gost_raw2(), gnutls_pubkey_import_gost_raw() import
   and export GOST parameters in the "native" little endian format used for these
   curves. This is an intentional incompatible change with 3.6.3.

** libgnutls: Added support for seperately negotiating client and server certificate types
   as defined in RFC7250. This mechanism must be explicitly enabled via the
   GNUTLS_ENABLE_CERT_TYPE_NEG flag in gnutls_init().

** gnutls-cli: enable CRL validation on startup (#564)

** API and ABI modifications:
gnutls_ctype_target_t: New enumeration
gnutls_record_set_max_early_data_size: Added
gnutls_certificate_type_get2: Added
gnutls_priority_certificate_type_list2: Added
gnutls_ffdhe_6144_group_prime: Added
gnutls_ffdhe_6144_group_generator: Added
gnutls_ffdhe_6144_key_bits: Added
