-A TLS/SSL connection established with these methods will understand the SSLv2,

+If the cipher list does not contain any SSLv2 ciphersuites (the default
+cipher list does not) or extensions are required (for example server name)
+a client will send out TLSv1 client hello messages including extensions and
+will indicate that it also understands TLSv1.1, TLSv1.2 and permits a
+fallback to SSLv3. A server will support SSLv3, TLSv1, TLSv1.1 and TLSv1.2
+protocols. This is the best choice when compatibility is a concern.
+
+If any SSLv2 ciphersuites are included in the cipher list and no extensions
+are required then SSLv2 compatible client hellos will be used by clients and
+SSLv2 will be accepted by servers. This is B<not> recommended due to the
+insecurity of SSLv2 and the limited nature of the SSLv2 client hello
+prohibiting the use of extensions.

 The list of protocols available can later be limited using the SSL_OP_NO_SSLv2,
-SSL_OP_NO_SSLv3, SSL_OP_NO_TLSv1 options of the B<SSL_CTX_set_options()> or
-B<SSL_set_options()> functions. Using these options it is possible to choose
-e.g. SSLv23_server_method() and be able to negotiate with all possible
-clients, but to only allow newer protocols like SSLv3 or TLSv1.
