Below you can find the life cycle for each version of protocol TLS, like TLS 1.3, including release dates and end of life (EOL) dates.

Transport Layer Security (TLS) is a cryptographic protocol that provides communications security over a computer network. Several versions of the protocols find widespread use in applications such as web browsing, email, instant messaging, and voice over IP (VoIP). Websites are able to use TLS to secure all communications between their servers and web browsers.
