Older Versions

allow to specify minimum used TLS version
new options: -1, --tlvs1, --tlsv1.0. --tlsv1.1, --tlsv1.2, --tlsv1.3
Note that rustls is used, when --tlsv1.3 is specified, otherwise native TLS is used.
allow HTTPS-only mode
new option: --proto
Note that --proto uses the same syntax as the respective curl option, but is used
to determine if HTTPS-only mode can be used. It does not forbit HTTPS requests, when
on HTTP is active.
