+ Changes between 1.0.1 and 1.1.0 [xx XXX xxxx]
+
+ *) If a candidate issuer certificate is already part of the constructed
+ path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case.
+ [Steve Henson]
+
+ *) Improve forward-security support: add functions
+
+ void SSL_CTX_set_not_resumable_session_callback(SSL_CTX *ctx, int (*cb)(SSL *ssl, int is_forward_secure))
+ void SSL_set_not_resumable_session_callback(SSL *ssl, int (*cb)(SSL *ssl, int is_forward_secure))
+
+ for use by SSL/TLS servers; the callback function will be called whenever a
+ new session is created, and gets to decide whether the session may be
+ cached to make it resumable (return 0) or not (return 1). (As by the
+ SSL/TLS protocol specifications, the session_id sent by the server will be
+ empty to indicate that the session is not resumable; also, the server will
+ not generate RFC 4507 (RFC 5077) session tickets.)
+
+ A simple reasonable callback implementation is to return is_forward_secure.
+ This parameter will be set to 1 or 0 depending on the ciphersuite selected
+ by the SSL/TLS server library, indicating whether it can provide forward
+ security.

+
+ *) Add Next Protocol Negotiation,
+ http://tools.ietf.org/html/draft-agl-tls-nextprotoneg-00. Can be
+ disabled with a no-npn flag to config or Configure. Code donated
+ by Google.
+ [Adam Langley <agl@google.com> and Ben Laurie]
+
+ *) Use type ossl_ssize_t instad of ssize_t which isn't available on
+ all platforms. Move ssize_t definition from e_os.h to the public
+ header file e_os2.h as it now appears in public header file cms.h
+ [Steve Henson]
+
+ *) New function OPENSSL_gmtime_diff to find the difference in days
+ and seconds between two tm structures. This will be used to provide
+ additional functionality for ASN1_TIME.
+ [Steve Henson]
+
+ *) New -sigopt option to the ca, req and x509 utilities. Additional
+ signature parameters can be passed using this option and in
+ particular PSS.
+ [Steve Henson]
+
+ *) Add RSA PSS signing function. This will generate and set the
+ appropriate AlgorithmIdentifiers for PSS based on those in the
+ corresponding EVP_MD_CTX structure. No application support yet.
+ [Steve Henson]
+
+ *) Support for companion algorithm specific ASN1 signing routines.
+ New function ASN1_item_sign_ctx() signs a pre-initialised
+ EVP_MD_CTX structure and sets AlgorithmIdentifiers based on
+ the appropriate parameters.
+ [Steve Henson]
+
+ *) Add new algorithm specific ASN1 verification initialisation function
+ to EVP_PKEY_ASN1_METHOD: this is not in EVP_PKEY_METHOD since the ASN1
+ handling will be the same no matter what EVP_PKEY_METHOD is used.
+ Add a PSS handler to support verification of PSS signatures: checked
+ against a number of sample certificates.
+ [Steve Henson]
+
+ *) Add signature printing for PSS. Add PSS OIDs.
+ [Steve Henson, Martin Kaiser <lists@kaiser.cx>]
+
+ *) Add algorithm specific signature printing. An individual ASN1 method
+ can now print out signatures instead of the standard hex dump.
+
+ More complex signatures (e.g. PSS) can print out more meaningful
+ information. Include DSA version that prints out the signature
+ parameters r, s.
