Changes between 0.9.5 and 0.9.5a [XX XXX 2000]
+ *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
+ is set; it will be thrown away anyway because each handshake creates
+ its own key.
+ ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
+ to parameters -- in previous versions (since OpenSSL 0.9.3) the
+ 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
+ you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
+ [Bodo Moeller]
+
*) New s_client option -ign_eof: EOF at stdin is ignored, and
'Q' and 'R' lose their special meanings (quit/renegotiate).
This is part of what -quiet does; unlike -quiet, -ign_eof
