OpenSSL CHANGES
_______________
- Changes between 1.0.0 and 1.1.0 [xx XXX xxxx]
+ Changes between 1.0.1 and 1.1.0 [xx XXX xxxx]
+
+ *) 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
whose return value is often ignored.

- Changes between 1.0.0a and 1.0.1 [xx XXX xxxx]
+ Changes between 1.0.0b and 1.0.1 [xx XXX xxxx]
+
+ *) Add EC_GFp_nistp224_method(), a 64-bit optimized implementation for
+ elliptic curve NIST-P224 with constant-time single point multiplication on
+ typical inputs. EC_GROUP_new_by_curve_name() will automatically use this
+ (while EC_GROUP_new_curve_GFp() currently won't and prefers the more
+ flexible implementations).
+
+ The implementation requires support for the nonstandard type __uint128_t,
+ and so is disabled by default. To include this in your build of OpenSSL,
+ use -DEC_NISTP224_64_GCC_128 on the Configure (or config) command line,
+ and run "make depend" (or "make update").

*) Permit abbreviated handshakes when renegotiating using the function
SSL_renegotiate_abbreviated().
Changes between 0.9.8o and 0.9.8p [xx XXX xxxx]
+ *) Fix for double free bug in ssl/s3_clnt.c CVE-2010-2939
+ [Steve Henson]
+
+ *) Don't reencode certificate when calculating signature: cache and use
+ the original encoding instead. This makes signature verification of
+ some broken encodings work correctly.
+ [Steve Henson]
+
*) ec2_GF2m_simple_mul bugfix: compute correct result if the output EC_POINT
is also one of the inputs.
