Changes between 1.1.1 and 3.0.0 [xx XXX xxxx]
+ *) Changed DH parameters to generate the order q subgroup instead of 2q.
+ Previously generated DH parameters are still accepted by DH_check
+ but DH_generate_key works around that by clearing bit 0 of the
+ private key for those. This avoids leaking bit 0 of the private key.
+ [Bernd Edlinger]
+
+ *) Added a new FUNCerr() macro that takes a function name.
+ The macro SYSerr() is deprecated.
+ [Rich Salz]
+
+ *) Significantly reduce secure memory usage by the randomness pools.
+ [Paul Dale]
+
+ *) {CRYPTO,OPENSSL}_mem_debug_{push,pop} are now no-ops and have been
+ deprecated.
+ [Rich Salz]
+
+ *) A new type, EVP_KEYEXCH, has been introduced to represent key exchange
+ algorithms. An implementation of a key exchange algorithm can be obtained
+ by using the function EVP_KEYEXCH_fetch(). An EVP_KEYEXCH algorithm can be
+ used in a call to EVP_PKEY_derive_init_ex() which works in a similar way to
+ the older EVP_PKEY_derive_init() function. See the man pages for the new
+ functions for further details.
+ [Matt Caswell]
+
+ *) The EVP_PKEY_CTX_set_dh_pad() macro has now been converted to a function.
+ [Matt Caswell]
+
+ *) Removed the function names from error messages and deprecated the
+ xxx_F_xxx define's.
+
*) Removed NextStep support and the macro OPENSSL_UNISTD
