 I've just released gnutls 3.6.9. This is a bug fix release on the
stable 3.6.x branch.

I'd like to thank everyone who contributed in this release:
Andreas Metzler, Daiki Ueno, Dmitry Eremin-Solenikov, Karsten Ohme,
Ludovic Courtès and Tim Rühsen.

The detailed list of changes follows; they can be seen in more detail
in our milestone tracker:


* Version 3.6.9 (released 2019-07-25)

** libgnutls: add gnutls_hash_copy/gnutls_hmac_copy functions that will create a copy
   of digest or MAC context. Copying contexts for externally-registered digest and MAC
   contexts is unupported (#787).

** Marked the crypto implementation override APIs as deprecated. These APIs are rarely
   used, are for a niche use case, but have significant side effects, such as preventing
   any internal re-organization and extension of the internal cipher API. The APIs remain
   functional though a compiler warning will be issued, and a future minor version update
   may transform them to a no-op while keeping ABI compatibility (#789).

** libgnutls: Added support for AES-GMAC, as a separate to GCM, MAC algorithm (#781).

** libgnutls: gnutls_privkey_sign_hash2 now accepts the GNUTLS_PRIVKEY_SIGN_FLAG_TLS1_RSA
   flag as documented. This makes it a complete replacement of gnutls_privkey_sign_hash().

** libgnutls: Added support for Generalname registeredID.

** The priority configuration was enhanced to allow more elaborate
   system-wide configuration of the library (#587).
   The following changes were included:
    - The file is read as an ini file with '#' indicating a comment.
    - The section "[priorities]" or global follows the existing semantics of
      the configuration file, and allows to specify system-wide priority strings
      which are accessed with the '@' prefix.
    - The section "[overrides]" is added with the parameters "insecure-hash",
      "insecure-sig", "insecure-sig-for-cert", "disabled-curve",
      "disabled-version", "min-verification-profile", "tls-disabled-cipher",
      "tls-disabled-mac", "tls-disabled-group", "tls-disabled-kx", which prohibit
      specific algorithms or options globally. Existing algorithms in the
      library can be marked as disabled and insecure, but no hard-coded
      insecure algorithm can be marked as secure (so that the configuration
      cannot be abused to make the system vulnerable).
    - Unknown sections or options are skipped with a debug message, unless
      the GNUTLS_SYSTEM_PRIORITY_FAIL_ON_INVALID environment parameter is
      set to 1.

** libgnutls: Added new flag for GNUTLS_CPUID_OVERRIDE
    - 0x20: Enable SHA_NI instruction set

** API and ABI modifications:
gnutls_crypto_register_cipher: Deprecated
gnutls_crypto_register_aead_cipher: Deprecated
gnutls_crypto_register_digest: Deprecated
gnutls_crypto_register_mac: Deprecated
gnutls_get_system_config_file: Added
gnutls_hash_copy: Added
gnutls_hmac_copy: Added
