+yaSSL Release notes, version 2.3.9b (2/03/2016)
+    This release of yaSSL fixes the OpenSSL compatibility function
+    X509_NAME_get_index_by_NID() to use the actual index of the common name
+    instead of searching on the format prefix.  Thanks for the report from
+    [email protected]  .  Anyone using this function should update.
