As part of removing SSLv3 support in a future release (as mentioned in
the 1.11.11 announcement note, copied below), I'm planning on also
removing support for processing SSLv2-mapped TLS client hellos.  This
has no affect on clients, or on servers which only talk to botan TLS
clients, but may affect servers with clients running old or
misconfigured versions of openssl and company which sometimes send
SSLv2 hellos.

As with the SSLv3 removal if this change to client hellos breaks your
application now is a good time to mention it, as once the code is
removed it will not be back. :)
