+  *) 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 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").

+     Sort table on each new add. This effectively makes the table read only
+     after all algorithms are added and subsequent calls to PKCS12_pbe_add
+     etc are non-op.
