Server and command line tools now support option --tls_version to specify the TLS version between client and server. Valid values are TLSv1.0, TLSv1.1, TLSv1.2, TLSv1.3 or a combination of them. E.g. --tls_version=TLSv1.3 --tls_version=TLSv1.2,TLSv1.3 In case there is a gap between versions, the lowest version will be used: --tls_version=TLSv1.1,TLSv1.3 -> Only TLSv1.1 will be available. If the used TLS library doesn't support the specified TLS version, it will use the default configuration. Limitations: SSLv3 is not supported. The default configuration doesn't support TLSv1.0 anymore. TLSv1.3 protocol currently is only supported by OpenSSL 1.1.0 (client and server) and GnuTLS 3.6.5 (client only).
