TLS Versions

Max TLS versions

This table lists the maximum supported version of connections, either from the Handshake version, or the first (non-GREASE) listed in the supported_versions extension.

Top supported_versions

This table breaks down the percent of connections that send the supported_versions extension (defined by TLS 1.3), and what version they support.
