+ Major changes between OpenSSL 0.9.3 and OpenSSL 0.9.4:
+
+ o Transparent support for PKCS#8 format private keys: these are used
+ by several software packages and are more secure than the standard
+ form
+ o PKCS#5 v2.0 implementation
+ o Password callbacks have a new void * argument for application data
+ o Avoid various memory leaks
+ o New pipe-like BIO that allows using the SSL library when actual I/O
+ must be handled by the application (BIO pair)
