The R66/R66-TLS split migration is missing
The migration for issue #287 (closed) (the R66 / R66-TLS split) is missing. This causes all R66-TLS servers and partners created before migrating to version 0.7.0 and above to be treated as plain R66 instead of R66-TLS.
With remote partners, this will cause the connection to fail because the partner is expecting a TLS connection, and receives a plain one instead. For local servers, this is a potential security breach, since the server will accept plaintext connections, instead of TLS ones.
