+Subject: [PATCH] Use version in SSL_METHOD not SSL structure.
+
+When deciding whether to use TLS 1.2 PRF and record hash algorithms
+use the version number in the corresponding SSL_METHOD structure
+instead of the SSL structure. The SSL structure version is sometimes
+inaccurate. Note: OpenSSL 1.0.2 and later effectively do this already.
