+ *) Revised BN_generate_prime_ex to not avoid factors 2..17863 in p-1
+ when primes for RSA keys are computed.
+ Since we previously always generated primes == 2 (mod 3) for RSA keys,
+ the 2-prime and 3-prime RSA modules were easy to distinguish, since
+ N = p*q = 1 (mod 3), but N = p*q*r = 2 (mod 3). Therefore fingerprinting
+ 2-prime vs. 3-prime RSA keys was possible by computing N mod 3.
+ This avoids possible fingerprinting of newly generated RSA modules.

+
+ *) Correct the extended master secret constant on EBCDIC systems. Without this
+ fix TLS connections between an EBCDIC system and a non-EBCDIC system that
+ negotiate EMS will fail. Unfortunately this also means that TLS connections
+ between EBCDIC systems with this fix, and EBCDIC systems without this
+ fix will fail if they negotiate EMS.

+
+ *) Changed the library initialisation so that the config file is now loaded
+ by default. This was already the case for libssl. It now occurs for both
+ libcrypto and libssl. Use the OPENSSL_INIT_NO_LOAD_CONFIG option to
+ OPENSSL_init_crypto() to suppress automatic loading of a config file.
+ [Matt Caswell]
+
+ *) Introduced new error raising macros, ERR_raise() and ERR_raise_data(),
+ where the former acts as a replacement for ERR_put_error(), and the
+ latter replaces the combination ERR_put_error()+ERR_add_error_data().
+ ERR_raise_data() adds more flexibility by taking a format string and
+ an arbitrary number of arguments following it, to be processed with
+ BIO_snprintf().
+ [Richard Levitte]
+
+ *) Introduced a new function, OSSL_PROVIDER_available(), which can be used
+ to check if a named provider is loaded and available. When called, it
+ will also activate all fallback providers if such are still present.
+ [Richard Levitte]
+
+ *) Enforce a minimum DH modulus size of 512 bits.
+ [Bernd Edlinger]
+
+ *) 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]
+
+ *) 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
+ [Rich Salz]
+
+ *) Removed DES_check_key. Also removed OPENSSL_IMPLEMENT_GLOBAL,
+ OPENSSL_GLOBAL_REF, OPENSSL_DECLARE_GLOBAL.
+ Also removed "export var as function" capability; we do not export
+ variables, only functions.
+ [Rich Salz]
+
+ *) RC5_32_set_key has been changed to return an int type, with 0 indicating
+ an error and 1 indicating success. In previous versions of OpenSSL this
+ was a void type. If a key was set longer than the maximum possible this
+ would crash.
