o Support for external crypto devices ('engine') is no longer
a separate distribution.
o New elliptic curve library section.
+ o New AES (Rijndael) library section.
+ o Change DES API to clean up the namespace (some applications link also
+ against libdes providing similar functions having the same name).
+ Provide macros for backward compatibility (will be removed in the
+ future).
+ o Unifiy handling of cryptographic algorithms (software and
+ engine) to be available via EVP routines for asymmetric and
+ symmetric ciphers.
+ o NCONF: new configuration handling routines.
+ o Change API to use more 'const' modifiers to improve error checking
+ and help optimizers.
+ o Finally remove references to RSAref.
+ o Reworked parts of the BIGNUM code.
+ o Support for new engines: Broadcom ubsec, Accelerated Encryption
+ Processing, IBM 4758.
+ o PRNG: query at more locations for a random device, automatic query for
+ EGD style random sources at several locations.
+ o SSL/TLS: allow optional cipher choice according to server's preference.
+ o SSL/TLS: allow server to explicitly set new session ids.
+ o SSL/TLS: support Kerberos cipher suites (RFC2712).
+ o SSL/TLS: allow more precise control of renegotiations and sessions.
+ o SSL/TLS: add callback to retrieve SSL/TLS messages.
+
+ Changes between OpenSSL 0.9.6c and OpenSSL 0.9.6d:
+
+ o Various SSL/TLS library bugfixes.
+ o Fix DH parameter generation for 'non-standard' generators.
