- updated to 3.4.0 (released 2015-04-08)
** libgnutls: Added support for AES-CCM and AES-CCM-8 (RFC6655 and RFC7251)
ciphersuites. The former are enabled by default, the latter need to be
explicitly enabled, since they reduce the overall security level.
** libgnutls: Added support for Chacha20-Poly1305 ciphersuites following
draft-mavrogiannopoulos-chacha-tls-05 and draft-irtf-cfrg-chacha20-poly1305-10.
That is currently provided as technology preview and is not enabled by
default, since there are no assigned ciphersuite points by IETF and there
is no guarrantee of compatibility between draft versions. The ciphersuite
priority string to enable it is "+CHACHA20-POLY1305".
** libgnutls: Added support for encrypt-then-authenticate in CBC
ciphersuites (RFC7366 -taking into account its errata text). This is
enabled by default and can be disabled using the %NO_ETM priority
string.
** libgnutls: Added support for the extended master secret
(triple-handshake fix) following draft-ietf-tls-session-hash-02.
** libgnutls: Added a new simple and hard to misuse AEAD API (crypto.h).
** libgnutls: SSL 3.0 is no longer included in the default priorities
list. It has to be explicitly enabled, e.g., with a string like
"NORMAL:+VERS-SSL3.0".
** libgnutls: ARCFOUR (RC4) is no longer included in the default priorities
list. It has to be explicitly enabled, e.g., with a string like
"NORMAL:+ARCFOUR-128".
** libgnutls: DSA signatures and DHE-DSS are no longer included in the
default priorities list. They have to be explicitly enabled, e.g., with
a string like "NORMAL:+DHE-DSS:+SIGN-DSA-SHA256:+SIGN-DSA-SHA1". The
DSA ciphersuites were dropped because they had no deployment at all
on the internet, to justify their inclusion.
** libgnutls: The priority string EXPORT was completely removed. The string (forwarded request 295652 from msmeissn)
