+ *) Version negotiation has been rewritten. In particular SSLv23_method(),
+ SSLv23_client_method() and SSLv23_server_method() have been deprecated,
+ and turned into macros which simply call the new preferred function names
+ TLS_method(), TLS_client_method() and TLS_server_method(). All new code
+ should use the new names instead. Also as part of this change the ssl23.h
+ header file has been removed.

+
*) Support for Kerberos ciphersuites in TLS (RFC2712) has been removed. This
code and the associated standard is no longer considered fit-for-purpose.
