The SSLlabs test wordings need a thorough review, to be accurate now that TLS1.3 is supported and included.
For example, these 2 wordings are clearly out of date:-
] The server supports only older protocols, but not the current best TLS 1.2. Grade capped to C. MORE INFO »
] No support for TLS 1.2, which is the only secure protocol version. MORE »
TLS1.2 is not "the current best".
TLS1.2 is minimum expected for good security, but not "the only secure" version now...
I expect there to be more related, outdated wording in there somewhere!.
Hope that helps, --Simon
