  Changes between 1.0.1a and 1.0.1b [xx XXX xxxx]
 
+  *) OpenSSL 1.0.0 sets SSL_OP_ALL to 0x80000FFFL and OpenSSL 1.0.1 and
+     1.0.1a set SSL_OP_NO_TLSv1_1 to 0x00000400L which would unfortunately
+     mean any application compiled against OpenSSL 1.0.0 headers setting
+     SSL_OP_ALL would also set SSL_OP_NO_TLSv1_1, unintentionally disablng
+     TLS 1.1 also. Fix this by changing the value of SSL_OP_NO_TLSv1_1 to
+     0x10000000L Any application which was previously compiled against
+     OpenSSL 1.0.1 or 1.0.1a headers and which cares about SSL_OP_NO_TLSv1_1
+     will need to be recompiled as a result. Letting be results in
+     inability to disable specifically TLS 1.1 and in client context,
+     in unlike event, limit maximum offered version to TLS 1.0 [see below].
